  英語, 研究論文（学術雑誌）, Deltanthura Shiraki, Shimomura & Kakui, 2022 is a monotypic paranthurid genus established for Deltanthura palpus Shiraki, Shimomura & Kakui, 2022, which was described from a single female lacking oostegites. It was concluded from the original description that D. palpus is neotenous, because the specimen lacked pereopod 7. Recently collected material revealed that the specimen originally described was a manca-stage individual, and that the condition of pereopod 7 differed among the ontogenetic stages: it is absent in smaller specimens (6.84–10.92 mm; mancae); it has only a few setae and a tiny unguis in middle-sized specimens (12.87–13.67 mm; smaller female-like specimens and a subadult male); and it is generally similar in shape to a pereopod 6 with many setae and a normal-sized unguis, but shorter and narrower (less than 0.7 times pereopod-6 length) in larger specimens (16.56–21.14 mm; a larger female-like specimen and adult males). We present an amended diagnosis for the genus and the amended key to the genera in Paranthuridae, suggest that primary males may be present in D. palpus, and briefly discuss the possibility that this species may be undergoing an evolutionary process toward the loss of pereopod 7 (true neoteny).

  英語, 研究論文（学術雑誌）, Abstract
  
  We describe the marine horsehair worm Nectonema shimadai sp. nov. , which was parasitic in a snapping shrimp ( Alpheus sp.) collected at 4 m depth from the coastal water of Kikaijima Island, Japan, northwestern Pacific. The nematomorph was a female, 49 mm in length and 340 μm in width, salmon-pink when alive, with a translucent anterior body region and a distinct anterior chamber. The 18S sequence from N. shimadai sp. nov. was 12.8%, 9.8%, 9.6%, and 9.3% divergent in Kimura 2-parametar (K2P) distance from Nectonema sp. parasitic in the isopod Natatolana japonensis , Nectonema sp. parasitic in the crab Chionoecetes bairdi , N. munidae , and N. agile , respectively. In an 18S tree, N. shimadai sp. nov. was the sister taxon to a clade comprising three decapod-parasitic species, and species sharing the same host group or ocean were not monophyletic. The tree may reflect genetically distant warm- and cold-water lineages within decapod-parasitic nematomorphs., 51027794

In this study, we examine gnathiid specimens obtained from the continental shelf area of western Japan from 1995 to 2023. As a result, we report the following findings. (1) Two new species of Caecognathia: C. tida sp. nov., C. inferoculus sp. nov. (2) Three new species of Gnathia: G. hayashiae sp. nov., G. toyoshiomaruae sp. nov., and G. tajirana sp. nov. (3) Redescription of G. consobrina (Monod, 1926) comb. nov. since the original description. (4) First record of G. koreana Song and Ming, 2018 from Japan. Most descriptions are based on male specimens but female and third stage praniza larva are described in G. hayashiae sp. nov. New distributional records are given for G. camuripenis Tanaka, 2004, G. kumejimensis Ota, 2012 and Thaumastognathia tanseimaruae Shimomura and Tanaka, 2008. Keys to genera of Gnathiidae and the Japanese species of Caecognathia and Gnathia are provided., 10432430

• A new genus and species of the spring-endemic Ostracoda (Cypricercinae, Cyprididae) and its genetic population structure among rheocrenic springs in Japan
  Mizuho Munakata; Hayato Tanaka; Keiichi Kakui
  Zoological Studies, 63, 51, 2024年12月31日, ［査読有り］, ［最終著者］, ［国際誌］
  英語, 研究論文（学術雑誌）, We describe the ostracod Lissostrandesia fonticola gen. et sp. nov. in the subfamily Cypricercinae McKenzie, 1971, collected from six rheocrenic springs in Japan. The populations sampled were separated by up to 1000 km, and some of them by one or two marine straits, which comprise significant barriers for freshwater animals. Lissostrandesia differs from the other 13 cypricercine genera in (1) lacking a groove and inner list on the anterior inner margin of the left valve; (2) having b and d setae on the fifth limb; (3) having d1 and d2 setae on the sixth limb; (4) having a stout attachment of the caudal ramus; (5) having a Triebel’s loop on the dorsal branch of the attachment; and (6) having a long free ventral branch, its length more than twice its width, and (7) having a free dorsal branch contributing to a tip on Triebel’s loop. These differences were enough to warrant establishment of a new tribe, Lissostrandesiini, to accommodate the new genus. We present a key to the genera in Cypricercinae. The maximum p-distance for the mitochondrial cytochrome c oxidase subunit I (COI) gene among six local populations was 0.662%, a low value indicative of conspecificity. In addition, four populations with sample sizes of 13–21 individuals shared two main COI haplotypes, indicating high apparent connectivity. A trend of decreasing genetic diversity from south to north suggests L. fonticola has had a longer history on Honshu Island and dispersed northward from there. Using the 16S rRNA gene as a marker, we detected the endosymbiotic bacterium Cardinium, a group of “reproduction-manipulating” bacteria, in five populations, suggesting that L. fonticola is parthenogenetic. Passive dispersal is the most likely explanation for the broad distribution of this species across strong geographic barriers.

• Nectonema horsehair worms (Nematomorpha) parasitic in the Tanner crab Chionoecetes bairdi, with a note on the relationship between host and parasite phylogeny

  Diseases of Aquatic Organisms, 159, 153, 157, Inter-Research Science Center, 2024年09月12日, ［査読有り］, ［筆頭著者, 責任著者］, ［国際誌］
  英語, 研究論文（学術雑誌）, Nectonema nematomorphs utilize marine crustacean hosts in their life cycle; 16 decapod and 1 isopod genera have been reported to date as host genera. This study reports the first case of Nectonema parasitic in the Tanner crab Chionoecetes bairdi, adding another known host genus. A single nematomorph juvenile was recovered from the body cavity of each of 2 ovigerous female crabs. A nucleotide sequence for the 18S rRNA gene (1854 bp) was determined from 1 Nectonema individual. The 18S sequence showed Kimura 2-parameter (K2P) distances of 10.0, 2.0, and 1.7% from 18S sequences from Nectonema sp. from an isopod host, N. agile, and N. munidae, respectively. In an 18S-based tree, the unknown species was the sister taxon to a clade comprising N. agile and N. munidae, both of which also utilize decapod hosts. The phylogenetic relationships among the 3 Nectonema species parasitic in decapods were not congruent with the phylogeny of the hosts, not supporting a hypothesis of nematomorph-host co-evolution.

  英語, 研究論文（学術雑誌）, Abstract
  
  The fundamental value of universal nomenclatural systems in biology is that they enable unambiguous scientific communication. However, the stability of these systems is threatened by recent discussions asking for a fairer nomenclature, raising the possibility of bulk revision processes for “inappropriate” names. It is evident that such proposals come from very deep feelings, but we show how they can irreparably damage the foundation of biological communication and, in turn, the sciences that depend on it. There are four essential consequences of objective codes of nomenclature: universality, stability, neutrality, and transculturality. These codes provide fair and impartial guides to the principles governing biological nomenclature and allow unambiguous universal communication in biology. Accordingly, no subjective proposals should be allowed to undermine them.

• Apseudes ranma sp. nov. (Tanaidacea: Apseudidae) found in a public aquarium, with notes on phylogeny and a presumptive stridulatory organ

  英語, 研究論文（学術雑誌）, We describe Apseudes ranma sp. nov. from the Port of Nagoya Public Aquarium, Nagoya, Japan. It resembles two congeners, Apseudes curtiramus (Guţu, 2007) and Apseudes orghidani Guţu and Iliffe, 1989, in having the rostrum triangular, wider than long, the carapace without lateral spines, distinct and round eye lobes, pereonites 3–6 with a pair of tongue-shaped anterolateral projections, and the pleotelson with two pairs of lateral projections, but differs from them in having lateral setae on the anterolateral margin of the carapace and a ventro-subproximal spine on the pereopod-1 basis, and in the number of spiniform setae on articles of pereopods 2–4. We determined partial nucleotide sequences for the cytochrome c oxidase subunit I (COI) and 18S rRNA (18S) genes in A. ranma sp. nov. for future DNA barcoding and phylogeny reconstruction. In an 18S tree, A. ranma sp. nov. was the sister taxon to Apseudes nipponicus Shiino, 1937, and this clade was the sister group to moderately supported Carpoapseudes clade. We discovered a presumptive stridulatory organ in A. ranma sp. nov. consisting of a cylindrical protrusion and knobbly area on the inner surface of each of the left and right chelipedal bases. The location of the protrusion and knobbly area suggests that these may be a plectrum and pars stridens, respectively., 13264296;11341431;10432430

• A new parasitic barnacle (Crustacea, Cirripedia, Rhizocephala, Mycetomorpha) from the abyssal zone in the northwestern Pacific

  英語, 研究論文（学術雑誌）, I describe the parasitic barnacle Mycetomorpha abyssalissp. nov. from the crangonid shrimp Sclerocrangon zenkevitchi collected from 3893–3890 m depth off the eastern coast of Iwate, Japan, northwestern Pacific. This is the first Mycetomorpha rhizocephalan from the abyssal zone and the third species in Mycetomorpha. Mycetomorpha abyssalissp. nov. differs from its congeners M. vancouverensis and M. albatrossi in (1) triangular shield lacking, (2) stalk one-quarter of length from posterior end of externa, (3) mantle opening clearly anterior to stalk, (4) different host genus, and (5) depth range much deeper. I determined partial sequences for the mitochondrial cytochrome c oxidase subunit I (COI) and 16S rRNA genes and nuclear 18S rRNA and 28S rRNA genes from M. abyssalissp. nov. for future DNA barcoding and phylogeny. Kimura 2-parameter distances between M. abyssalissp. nov. and M. vancouverensis were 21.2% (16S), 0.6% (18S), and 1.5% (28S)., 39595807;13264296

  英語, 研究論文（学術雑誌）, We compared the body size (carapace width, CW) of the first free-living instar individuals, or mancae 2, and of the smallest ovigerous individuals, between two simultaneously hermaphroditic tanaidacean species, Apseudes nipponicus Shiino, 1937 and Apseudes sp. The former species is 2.2 times larger, with a CW of 2.61 mm in the smallest ovigerous individual, compared to 1.17 mm in the latter. Average CWs of manca 2 individuals were 0.51 mm (A. nipponicus, n = 3, 0.50-0.51 mm) and 0.38 mm (Apseudes sp.: n = 9, 0.38-0.39 mm), meaning that A. nipponicus mancae 2 were 20% as large as the smallest ovigerous individuals, whereas those of Apseudes sp. were 32% as large. The proportionally larger juveniles in the smaller species are consistent with the progenetic hypothesis that Apseudes sp. is achieving earlier maturation as females., 13264296

  日本語, 研究論文（学術雑誌）, Fotolaimus cavussp. nov. was described from a submarine anchialine cave called Akuma-no-yakata on the Shimoji Island, Miyako Island Group, Ryukyu Islands, southwestern Japan. This is the first free-living marine nematode isolated from a submarine cave in Japan, and the third species of the genus Fotolaimus. This new species differs from its congeners by its small body size, wide amphids, long buccal cavity, long conico-cylindrical tail, and proximally curved gubernaculum. We provide amended dichotomous keys to genera in the subfamily Oncholaiminae and species in Fotolaimus. We also analyzed partial DNA sequences encoding ribosomal small subunit RNA and cytochrome c oxidase subunit I from Fotolaimus cavussp. nov. and six other species of Oncholaimidae collected from Japanese waters. The phylogenetic tree based on the ribosomal small subunit RNA sequences using maximum likelihood analysis suggested a close relationship between Fotolaimus and Wiesoncholaimus as well as Oncholaimus. The topology of the tree was similar to those from previous studies; however, it suggested a new phylogenetic position of Adoncholaimus as a sister clade for Viscosia and Oncholaimus., 31062673

  英語, 研究論文（学術雑誌）, We establish the new podocerid genus Capropodocerus gen. nov. for the two new species Capropodocerus tagamaru gen. et sp. nov. (collected from 775–800 m depth in the Kumano Sea, Japan) and Capropodocerus kamaitachi gen. et sp. nov. (collected from 840–873 m depth off the eastern coast of Miyagi, Japan). Capropodocerus shares elongate pereonites 1–3 with Neoxenodice but differs from the latter in lacking uropod 2 and in having pereonite 3 at least twice as long as pereonite 4. Capropodocerus is also similar to Laetmatophilus and Leipsuropus in having only two pairs of uropods but differs from them in having i) pereonite 1 longer than the head and ii) pereonite 3 at least twice as long as pereonite 4; Capropodocerus has three urosomes and Laetmatophilus has two urosomes. The two species in Capropodocerus differ in i) the length ratio of the antenna 1 peduncle to the flagellum, ii) the shape of the gnathopod 2 palm, iii) the presence or absence of a mid-posterior triangular projection on the gnathopod 2 dactylus, and iv) the length ratio of the basis to the merus of pereopod 3. A key to all genera in Podoceridae is provided., 10432431;11341431

• Protogynous hermaphroditism in Crustacea: a new example from Tanaidacea

  Canadian Journal of Zoology, 100, 8, 481, 487, Canadian Science Publishing, 2022年08月, ［査読有り］, ［筆頭著者, 責任著者］
  英語, 研究論文（学術雑誌）, Hermaphroditism has been widely reported in the Crustacea, but protogyny, in which females change to males, is apparently rare and restricted to the peracarid orders Isopoda and Tanaidacea. In the latter, protogyny has been demonstrated in only seven species representing six genera by rearing experiments and indicated for several other genera and species through morphology. Here, we show through rearing experiment and histological observations, protogynous hermaphroditism in the tanaidacean species Nesotanais sp. aff. ryukyuensis Kakui, Kajihara and Mawatari, 2010. Our rearing experiment and size distribution data for wild individuals showed that females can change sex at various sizes (= ages). We found one individual identified externally as a female containing both ovaries and testes, indicating that overt female individuals undergo a short transitional phase as simultaneous hermaphrodites before the sex-change molt. We discuss the relationship among the wide size distribution of sex-changing females, the short life span of males, and the tube-dwelling mode of life., 13264296;11341431;10905851

  Journal of Helminthology, 96, Cambridge University Press (CUP), 2022年05月, ［査読有り］, ［筆頭著者, 責任著者］
  英語, 研究論文（学術雑誌）, Abstract
  
  We report the first mermithid nematode found to be parasitic in a marine tanaidacean crustacean. Ten host tanaidaceans were collected from a depth of 52 m in Otsuchi Bay, Iwate, Japan, north-western Pacific, and identified as a species in the tanaidid genus Zeuxo Templeton, 1840. Nematodes occurred in the host's body cavity; in one case, at least two individuals inhabited a single host. We provide a brief description and illustrations of the morphology of the nematode. In a phylogenetic reconstruction based on the 18S ribosomal RNA gene, the nematode nested in a clade otherwise containing mermithids from terrestrial or freshwater hosts, showing an expansion in host utilization in Mermithidae Braun, 1883 from terrestrial/freshwater hosts to a marine organism.
• Taxonomy and natural history of Cavernocypris hokkaiensis sp. nov., the first ostracod reported from alpine streams in Japan

  英語, 研究論文（学術雑誌）, We describe the cypridoidean ostracod Cavernocypris hokkaiensis sp. nov. from riverbed sediments in an alpine stream at an elevation of ca. 1850 m in the Taisetsu Mountains, Hokkaido, Japan. This species differs from congeners in having (1) the outer surface of the carapace smooth, with sparse, tiny setae, but without shallow pits; (2) the carapace elongate rather than triangular in lateral view; (3) the antennula consisting of seven podomeres; (4) first palpal podomere of maxillula with five dorsodistal and one ventro-subdistal setae; (5) the fifth limb lacking setae b and d; and (6) the fifth limb lacking a vibratory plate. We provided the key to the Cavernocypris species. We determined partial sequences for the cytochrome c oxidase subunit I (COI; cox1) and 18S rRNA (18S) genes in C. hokkaiensis. Our sample contained only females, and we obtained a partial 16S rRNA sequence for the endosymbiotic bacterium Cardinium from C. hokkaiensis, indicating the possibility that this ostracod species reproduces parthenogenetically. Our field survey and observations of captive individuals suggested that C. hokkaiensis may be endemic to the Taisetsu Mountains, with a low population density, narrow distributional range, and slow maturation to sexual maturity.

  英語, 研究論文（学術雑誌）, We describe a new paranthurid isopod genus and species, Deltanthura palpusgen. et sp. nov., collected from a depth of 805–852 m off the southern coast of Mie prefecture, Japan. Deltanthura is similar to Pseudanthura Richardson, 1911 in having a triangular pleotelson, acute mandible with a 3-articulate palp, a maxillipedal endite, and a tapering uropodal exopod, but differs in having eyes and neotenous characters (reduced pereonite 7 and pereopods 7 lacking). Deltanthura and four paranthurid genera (Califanthura Schultz, 1977, Colanthura Richardson, 1902, Cruranthura Thomson, 1946, and Cruregens Chilton, 1882) share neotenous characters, but in Deltanthura the mandible is acute, with a 3-articulate palp and maxillipedal endites are present. Califanthura minuta Kensley & Heard, 1991 may belong in Deltanthura as they share the triangular pleotelson and tapering uropodal exopod, but we refrain from transferring it to Deltanthura as its description lacks the other diagnostic characters of Deltanthura. We provide a revised key to all genera in Paranthuridae Menzies & Glynn, 1968.

  英語, 研究論文（学術雑誌）, We describe a new typhlotanaid species, Hamatipeda kohtsukai sp. nov., collected from between 167 and 488 m depth in the Sagami Sea, Japan. This is the first record of Hamatipeda from the northern hemisphere. Hamatipeda kohtsukai resembles Hamatipeda trapezoida from the Subantarctic region in having pereonites 1-3 widest anteriorly (not rectangular), but differs from it in the length ratio of antennal articles 4/5; the number of setae on the dactyli of pereopods 1-3, ischia of pereopods 4-6, and carpi of pereopods 4-6; the shape of the unguis of pereopods 4-6; and the shape of the uropodal endopod. We determined partial sequences for the cytochrome c oxidase subunit I (COI; cox1) and 18S rRNA (18S) genes in H. kohtsukai. A phylogenetic reconstruction based on the 18S sequences recovered a highly supported Typhlotanaidae clade containing H. kohtsukai and Typhlotanais mixtus, with Paranarthrura sp.

  英語, 研究論文（学術雑誌）,
  Tanaidaceans are small benthic crustaceans that mainly inhabit diverse marine environments, and they comprise one of the most diverse and abundant macrofaunal groups in the deep sea. Tanaidacea is one of the most thread-dependent taxa in the Crustacea, constructing tubes, spun with their silk, for shelter. In this work, we sequenced and assembled the comprehensive transcriptome of 23 tanaidaceans encompassing 14 families and 4 superfamilies of Tanaidacea, and performed silk proteomics of Zeuxo ezoensis to search for its silk genes. As a result, we identified two families of silk proteins that are conserved across the four superfamilies. The long and repetitive nature of these silk genes resembles that of other silk-producing organisms, and the two families of proteins are similar in composition to silkworm and caddisworm fibroins, respectively. Moreover, the amino acid composition of the repetitive motifs of tanaidacean silk tends to be more hydrophilic, and therefore could be a useful resource in studying their unique adaptation of silk use in a marine environment. The availability of comprehensive transcriptome data in these taxa, coupled with proteomic evidence of their silk genes, will facilitate evolutionary and ecological studies., 10432430;11341431;13264296;10432431

  英語, 研究論文（学術雑誌）, Two species of dirivultid copepod (Siphonostomatoida), Stygiopontius senckenbergi Ivanenko & Ferrari, 2013 and Dirivultus kaiko sp. nov., were discovered from hydrothermal vent fields in the Okinawa Trough, the western North Pacific. Since S. senckenbergi was originally described based on two adult males from the New Ireland Fore-Arc system, Papua New Guinea, the discovery here represents the second record. This species was attached on ventral setae covered with filamentous bacteria of the deep-sea squat lobster Shinkaia crosnieri (Decapoda: Munidopsidae). The female of S. senckenbergi is described for the first time as well as the nauplius I and the copepodid IV. Sexual dimorphism is shown on several appendages (i.e. antennule, leg 2 and leg 5). The nauplius I shows typical lethithotrophic characteristics. Dirivultus kaiko sp. nov., which was found on the tentacular crown of the siboglinid tubeworm Lamellibrachia columna, differs from its two congeners by the antennule, maxilliped and leg 5 of both sexes. These are the second and third dirivultid species to be reported from Japan., 11341431

• Unexpected low genetic differentiation between Japan and Bering Sea populations of a deep-sea benthic crustacean lacking a planktonic larval stage (Peracarida: Tanaidacea)
  Keiichi Kakui; Hidetaka Nomaki; Hironori Komatsu; Yoshihiro Fujiwara
  Biological Journal of the Linnean Society, 131, 3, 566, 574, Oxford University Press ({OUP}), 2020年11月06日, ［査読有り］, ［筆頭著者, 責任著者］
  英語, 研究論文（学術雑誌）, Information on the extent, diversity and connectivity of populations is lacking for most deep-sea invertebrates. Species of the order Tanaidacea (Crustacea), one of the most diverse and abundant macrofaunal groups in the deep sea, are benthic, lack a planktonic larval stage, and thus would be expected to have narrow distributional ranges. However, with molecular evidence from the COI gene, we show here that the deep-sea tanaidacean Carpoapseudes spinigena has a distributional range spanning at least 3700 km, from off northern Japan to the south-eastern Bering Sea. Living individuals found in a sediment core indicated that the species is a sedentary burrower. COI analyses revealed a low level of genetic diversity overall, and low differentiation (p-distance, 0.2–0.8%) between the Japan and Bering Sea populations. One hypothesis to explain the low genetic diversity over a broad region is that the Japan population was founded by individuals transported by ocean currents from the Bering Sea. However, due to limited data, other explanations cannot be ruled out. Our results indicate that continued sampling is of fundamental importance to understanding how genetic and taxonomic diversity originate and are maintained in the deep sea., 11341431

• New replacement name for a homonym in Lepeophtheirus (Crustacea: Copepoda: Caligidae)

  英語, 研究論文（学術雑誌）, Markevich (1940) established Pseudolepeophtheirus Markevich, 1940 for Pseudolepeophtheirus longicauda Markevich, 1940 based on copepods collected from the pleuronectid fish Platichthys stellatus (Pallas, 1787). Dojiri & Ho (2013) synonymized the genus and the species with Lepeophtheirus Nordmann, 1832 and Lepeophtheirus parvicruris Fraser, 1920, respectively. Later, Homma et al. (2020) resurrected Markevich’s species as a member of Lepeophtheirus, i.e., as L. longicauda (Markevich, 1940). The last component of the names of both genera is ‘phtheirus’ (transliterated from the Greek φθειρ; Nordmann 1832: 30), a masculine noun, and thus under Article 30.1.2 of the International Code of Zoological Nomenclature (hereinafter, Code; International Commission on Zoological Nomenclature 1999), both generic names are also masculine. The species-group name longicauda might be regarded as either a noun in apposition or as an adjective in the feminine gender, and Markevich (1940) did not specify his intention in this regard. Bearing in mind that ‘cauda’, meaning ‘tail’, actually is a feminine Latin noun and that Markevich did not change the final ‘-a’ to ‘-us’ to match the masculine gender of the genus, we deem that longicauda Markevich, 1940 is a noun in apposition, a position supported by Article 31.2.2 of the Code.

• First in situ observations of behavior in deep-sea tanaidacean crustaceans
  Kakui K; Fujiwara Y
  Zoological Science, 37, 4, 303, 306, 2020年08月03日, ［査読有り］, ［筆頭著者, 責任著者］, ［国内誌］
  英語, 研究論文（学術雑誌）, We report on the behavior of a deep-sea tanaidacean, Gigantapseudes sp. (Apseudomorpha: Gigantapseudidae), recorded at the depths of 6446-6447 m by the manned submersible Shinkai 6500. From recordings of at least three individuals walking on the sea floor, we confirm that Gigantapseudes sp. is epibenthic, as previously inferred from leg shape. One individual was recorded entering a hole. All individuals in the videos kept pereopods 4 raised from the seafloor while walking, implying that those legs have a function other than for walking, such as mechano- or chemoreception, or posture control. Our in situ observations of behavior are the first for any deep-sea tanaidacean and illustrate the importance of recording high-resolution videos in the deep sea and archiving them for future use. Our identification of Gigantapseudes sp. from video footage provides the first record of this genus from Japanese waters and extends the northern limit of the known generic distribution.

  日本語, 研究論文（学術雑誌）, Preliminary results of the deep-sea faunal survey conducted from the TR/V Seisui-maru of Mie University in April 2019 are presented. A total of 20 taxonomists and ecologists working on a wide variety of animal taxa participated in this survey. Surveyed areas included the Kumano Sea（off Mie Prefecture）and south of the Kii Strait（off Tanabe Bay, Wakayama Prefecture）， at depths of 112－775 m. Sampling gears employed were beam trawl and biological dredge. The collection is represented by macrobenthos and meiobenthos from nine animal phyla, including echinoderms, arthropods, molluscans and annelids. The number of phyla occurring in each station varied from seven to eight. The station with most diverse fauna at the phylum level was St. 3B（south of the Kii Strait, 775－661 m depth, mud bottom）．Meiofauna includes priapulids, nematodes and small arthropods such as copepods, tanaidaceans, amphipods, isopods and cumaceans. In addition to freeliving species, cnidarians symbiotic on a gastropod and an antipatharian, and crustaceans parasitic on a fi sh and sea urchins were also collected. Preliminary identifi cations are given for Asteroidea, Ophiuroidea, Holothuroidea, Crinoidea, Cyclopoida, Siphonostomatoida, Tanaidacea, Isopoda, Decapoda, Mollusca, polychaetes, Bryozoa, Cnidaria and Nemertea., 13264296

  英語, 研究論文（学術雑誌）, We describe Hexapleomera sasuke sp. nov. and provide a supplemental redescription of Hexapleomera urashima Tanabe et al., both of which are based on specimens collected in Japan. Hexapleomera sasuke closely resembles H. urashima, sharing a uropod with four articles, maxillipedal endites with two tiny dorso-subdistal and two distal spiniform setae, a labium with the palp fused to the outer lobe, and the pereopod-1 propodus with an inner subdistal plumose seta. The new species differs from H. urashima in having the basal article of pleopod 3 with three outer plumose setae, the chelipedal carpus with three or four dorsodistal simple setae, the region between the bases of the chelipedal dactylus and fixed finger with three or four simple setae, and deeply pigmented pleopodal rami. We determined partial sequences of the cytochrome c oxidase subunit I (COI) gene (655 nt) from H. sasuke, which proved to be 15.0–15.3% divergent from H. urashima in Kimura 2-parameter (K2P) distance; also in partial sequences of 18S rRNA gene (1888 nt after alignment), 0.8% divergent (K2P distance) was detected between two species. Based on morphology and molecular data, we discuss phylogenetic relationships within Hexapleomera, and propose two morphologically distinct groups, the robusta group and the wombat group., 11341431
• Two new and one known species of Phanodermatidae (Nematoda: Enoplida) from Sagami Bay, Japan

  英語, 研究論文（学術雑誌）, Two new and one known species of free-living marine nematode belonging to the family Phanodermatidae are described. They were collected during the 12th Japanese Association for Marine Biology (JAMBIO) Coastal Organism Joint Survey off Jogashima, Japan in Sagami Bay, North Pacific Ocean. Phanodermopsis kohtsukai sp. nov. differs from the congeners by the shape of the tail, the longer spicules, and the absence of the gubernaculum. Micoletzkyia nakanoi sp. nov. differs from the congeners by the absence of a circle of cervical setae, the proportion of the tail, the cylindrical gubernaculum without projection, and the position of the vulva. Crenopharynx caudata (Filipjev, 1927) comb. nov. is transferred from the genus Phanodermopsis based on the presence of the long spicules. The morphological characters of the newly collected specimens of C. caudata comb. nov. are in excellent agreement with those shown in the original description of the specimens from Arctic Russia and the previous redescription of the specimens from Skagerrak. The new diagnoses and species lists for these three genera and two dichotomous keys to the males of Micoletzkyia and Crenopharynx are provided.

  英語, The solitary entoproct Loxosoma axisadversum Konno, 1972 was found on the body surface of the maldanid polychaete Nicomache personata Johnson, 1901 obtained among roots of the seagrass Phyllospadix iwatensis Makino collected at a depth of about 1m in Oshoro Bay, Hokkaido, Japan. The species had previously been known from elsewhere in northern Japan, attached to another maldanid, Nicomache minor Arwidsson, 1907. The morphology of the new material is briefly described with photographs taken in life. A preliminary phylogenetic analysis using concatenated partial sequences of the mitochondrial cytochrome c oxidase subunit I (COI) gene, as well as the nuclear 18S and 28S rRNA genes, placed L. axisadversum as the sister taxon to all the rest of Solitaria included in the analysis, indicating non-monophyly of the genus Loxosoma Keferstein, 1862.

• Two new shallow-water species of Agathotanais (Crustacea: Tanaidacea) from Japan.

  英語, 研究論文（学術雑誌）, We describe two shallow-water species of Agathotanais, A. misakiensis sp. nov. and A. toyoshioae sp. nov., from Japan. Agathotanais misakiensis was collected from 211-493m depth in the Sagami Sea, North Pacific Ocean. It closely resembles A. ghilarovi Kudinova-Pasternak, 1989, but differs in having shorter pereonites 3 and 4, all pleonites narrower than pereonite 6, and a shorter article 3 in the antennule. Agathotanais toyoshioae, collected from 95m depth in the Genkai Sea, Sea of Japan, is very similar to A. spinipoda Larsen, 1999. The former can be distinguished from the latter by its narrower pleonites, the presence of a ventral keel on pleonites 1 and 2, and the presence on the basis and absence on the carpus and propodus of small spines on pereopods 4-6.

  本研究では、１）洞窟水圏性動物の種多様性、２）洞窟水圏性動物の分子系統・適応進化、３）洞窟水圏における動物群集の構造と個体群維持機構の3つの主要研究テーマに注力した調査研究を実施し、当該地域の洞窟水圏における生物多様性の全容を解明することを目的としている。
  2021年度は、沖縄島と伊江島の海底洞窟における合同野外調査を実施し、さらに徳之島・与論島・与那国島における陸域の洞窟での予備的な野外調査を実施し、2022年度以降の合同調査に備える予定であったが、新型コロナウイルス感染症の影響で調査対象の島々への渡航が厳しく制限される状況に陥り、予定を変更することになった。
  実際、海底洞窟の合同調査は規模を縮小して沖縄島のみで実施し、陸域の洞窟調査は沖永良部島、与論島、多良間島の３カ所に変更した。しかし、初年度（2020年度）及び2021年度にて得られたデータをもとに、以下のような実績を挙げることができた。
  「１）洞窟水圏性動物の種多様性」と「２）洞窟水圏性動物の分子系統・適応進化」については、対象洞窟にて採集された生物の種同定を進め、DNAバーコーディング作業を予定通り進めることができた。
  一方、「３）洞窟水圏における動物群集の構造と個体群維持機構」については、共同研究者が考案した海底洞窟の3D測量手法を沖縄島の海底洞窟にて試験実施した。3D測量図は洞窟形態の特性を可視化するものであり、生物研究を劇的に進展させることが予想されることから、次年度（2022年度）に早急な完成を目指す予定である。また、多良間島において、同島固有の地下水性甲殻類（タラマメアミ）を保護・保全するための生態研究を開始した。
  これらの研究成果（の一部）として、3編の研究論文の出版と、１題の学会発表を実施することができた。また、さらに複数（3編）の論文投稿も行い、これらは2022年度に出版を予定している。

  角井敬知
  本研究はタナイス目甲殻類の多様化に関係する第1歩脚の機能・形態("脚型")の進化史解明を目指すもので,本年度は以下の成果を挙げた.
  タナイス目の分子系統解析の論文を公表した.亜目・上科間の系統関係を初めて明らかにし,得られた系統関係と形態的特徴に基づき分類体系を現行の3亜目3上科から2亜目4上科に変更した.
  所属上科に議論のあったArctotanais alascensisの系統位置を決定,論文として公表した.詳細な形態観察および分子系統解析により,本種がタナイス上科に属することを明らかにした.また,本種に鋏脚座節という,同上科のTanais属と近縁とされるネオタナイス上科のみで報告されていた構造を確認し,2上科の近縁性についてより強い支持を得た.
  アプセウデス亜目の側系統性を示唆する結果を得た.Longiflagrum属とカリアプセウデス科は現在アプセウデス亜目に属しているが,進行中の分子系統解析の結果には,2分類群がタナイス亜目と姉妹群を形成するという結果も含まれた.なお,カリアプセウデス科はタナイス亜目のみで知られる「出糸型」生活も行う可能性が示唆されている科であるため,「出糸型」がアプセウデス亜目に起源するという仮説を立て,組織学的手法も導入した研究を計画中である.
  アプセウデス亜目内で祖先的な脚型と考えられている「俳徊型」を呈する2科のDNAサンプルを作成した.パグラプセウドプシス科は,タイでDr.Angsupanichと共同調査を行い採集した.ギガンタプセウデス科は,琉球海溝から得られた1個体を貸借できた.現在解析を進めているところであるが,前者は貝棲型のグループと姉妹群を形成する派生的なグループであるという結果が得られている.
  なお本年度は上記研究以外に,採集調査中に得た標本に基づき2報の記載論文を共同で執筆し,成果を学会大会で発表した.
