English, Scientific journal, Abstract

A new flathead Rogadius azizahae (Platycephalidae) is described on the basis of five specimens [102.5–107.8 mm standard length (SL)] collected off the east coast of the Malay Peninsula, southern South China Sea. The new species is morphologically similar to Rogadius mcgroutheri Imamura, 2007, known from the Coral Sea off eastern Australia and New Caledonia, the two species sharing most diagnostic characters, including a minute, weakly developed antrorse spine on the preopercle [vs. a long, stout antrorse spine present in Rogadius asper (Cuvier in Cuvier & Valenciennes, 1829), Rogadius fehlmanni Knapp, 2012, and Rogadius pristiger (Cuvier in Cuvier & Valenciennes, 1829)]; usually a single preocular spine [vs. 2–4 in R. fehlmanni and 2–5 in Rogadius welanderi (Schultz in Schultz et al., 1966)]; no accessory spines along the preocular spine base [vs. present in R. fehlmanni and Rogadius serratus (Cuvier in Cuvier & Valenciennes, 1829)]; and no longitudinal black band on the caudal fin (vs. present in Rogadius patriciae Knapp, 1987). The new species can also be distinguished from R. mcgroutheri by having 11 dorsal‐fin soft rays [vs. 11 or 12, modally 12 (25 of 30 specimens) in the latter]; 7 lower gill rakers [vs. 5–7, modally 6 (21 of 30)]; the caudal fin brown basally, broadly whitish (semitranslucent) anteriorly and almost entirely brown on the posterior half (vs. ca. 4 irregular variously sized vertical rows of black blotches); the pelvic fin with ca. 6–8 rows of narrow, wavy black bands or dotted lines (vs. largely brownish, with no defined bands or spots); a relatively large orbit, its diameter 12.4–12.8 (mean 12.6)% SL [vs. 11.4–12.3 (11.7)% SL in 100–110 mm SL specimens]; and relatively narrow interorbital region, its width 1.3–1.5 (mean 1.4)% SL [vs. 1.7–2.2 (1.9)% SL]. DNA barcoding also indicated distinct divergence (14.3–14.4% uncorrected p‐distance) between the new species and R. mcgroutheri. A revised key to species of Rogadius is provided.

English, Scientific journal, The smallknob flathead, Thysanophrys papillaris Imamura et Knapp, 1999, is redescribed based on six specimens collected from southern Taiwan, which constitutes a northward range extension of the species [previously recorded from the Andaman, Timor, and Arafura seas (eastern Indian Ocean), and Nha Trang, Vietnam (western Pacific Ocean)]. Thysanophrys papillaris is distinguished from all congeneric species in having a combination of 11 second dorsal-fin rays, 12 anal-fin rays, 58–75 scale rows below the lateral line (slanting downward and forward), a longer snout (snout length / orbital diameter ratio 1.1–1.3), 1 or 2 small papillae on the eye, the upper iris lappet with short branches, a single preorbital spine and 3–5 suborbital spines. Previously suggested intraspecific variation in the number of eye papillae is confirmed.

First northwestern Pacific record of Thysanophrys randalli (Teleostei: Platycephalidae) from Kochi Prefecture, Japan and morphological comparisons with T. chiltonae
Motomura Hiroyuki; Taguchi Jumpei; Imamura Hisashi; Matsunuma Mizuki
Japanese Journal of Ichthyology, 一般社団法人 日本魚類学会, 2020, [Peer-reviewed]
Japanese, <p>During an ichthyofaunal survey of southern Japan, a single specimen (74.9 mm standard length; SL), collected at a depth of 8 m off Kashiwa-jima Island, Kochi Prefecture in June 1992, was found in the fish collection of the National Museum of Nature and Science, Tsukuba, Japan. The specimen was subsequently identified as a species of <i>Thysanophyrys</i> Ogilby, 1898, having the following combination of characters: dorsal surface of head lacking tubercles, suborbital ridge with six distinct spines (including one preorbital spine), lateral-line scales with two exterior openings posteriorly, ocular papillae absent, interopercular flap absent, and well developed sensory tubes on upper cheek region. The specific identification as <i>T. randalli</i> Knapp, 2013 was based on the short snout (length 10.1% of SL), a single preocular spine, no supraocular tentacles, the iris lappet without branches, interopercle expanded posteroventrally, and six scale rows between the second dorsal-fin origin and lateral line. <i>Thysanophyrys randalli</i> having been recorded previously only from the western Indian Ocean and Pacific Ocean north to Kiribati, the Kochi specimen represents the first northwestern Pacific (including Japanese waters) and northernmost records of the species. The species is compared in detail with the closely related congener <i>Thysanophyrys chiltonae</i> Schultz, 1966. In Japanese waters, both species occur around the southern oceanic islands. The new standard Japanese name "Kokuchikuroshimagochi" is proposed for <i>T. randalli</i> ("Kuroshimagochi" applied to <i>T. chiltonae</i>).</p>

English, Scientific journal, The validity of the platycephalid species Platycephalus clavulatus Cantor, 1849, described from a single specimen collected in the sea of Pinang (=Penang), Malaysia, is evaluated. Although it has been suggested that the holotype of the species is a specimen registered as BMNH 1860.3.19.270 in the Natural History Museum, London (BMNH), which is identifiable as Cociella punctata (Cuvier, 1829), the total length (TL) of the holotype reported by Cantor is 5 7/8 inches (=149 mm), significantly longer than the damaged BMNH specimen, which is estimated to have had a TL of 121 mm. According to the original description of P. clavulatus, the holotype has 11 second dorsal and anal fin rays, one preorbital spine, and two suborbital spines, values which agree with those of C. punctata, a species widely distributed in the western Pacific and the Indian Ocean, including Penang. Although these characters are also present in Cociella crocodila (Cuvier, 1829), that species is known only from Japan, Korea, China, and Taiwan. We conclude that P. clavulatus is conspecific with C. punctata and is a junior synonym of that species.

Validity of Platycephalus grandispinis Cuvier, 1829, with priority over Platycephalus longispinis Macleay, 1884 (Actinopterygii: Scorpaeniformes: Platycephalidae)
IMAMURA Hisashi
Species Diversity, 18, 2, 183, 192, Japanese Society of Systematic Zoology, Nov. 2013, [Peer-reviewed]
English, Scientific journal, The taxonomic status of Platycephalus grandispinis Cuvier, 1829 was investigated. Although the holotypes of P. grandispinis and Platycephalus longispinis Macleay, 1884 closely resemble each other, having several characters in common (e.g., 14 second dorsal and anal fin rays, ca. 80 lateral line scales, the interorbit much narrower than the orbital diameter, no distinct interopercular flap, the supraoccipital with a ridge, and the lower preopercular spine much longer than the upper), they differ in the development of the skinny sensory tubes of the preopercle, which are more numerous and better developed in the former. After a detailed examination of the two holotypes and specimens referable to P. grandispinis and P. longispinis from southwestern to southeastern Australia, it was determined that these two nominal species are synonyms. Furthermore, the skinny sensory tubes tend to become more well developed with growth and to show a geographic cline, such a cline in any feature being recognized in the Platycephalidae for the first time. A cline was also recognized in the suborbital width, with a tendency for a greater width in the western population than the eastern. This study provides a detailed redescription of P. grandispinis, which has priority over P. longispinis.

Phylogenetic relationships of the suborder Notacanthoidei (Teleostei: Albuliformes) reassessed from osteological characters, with a proposed new classification

Mem Fac Fish Sci Hokkaido Univ, 54, 1/2, 1, 28, Faculty of Fisheries Sciences, Hokkaido University, Dec. 2012
English, Research institution, The phylogenetic relationships of Notacanthoidei were reassessed on the basis of osteological characters and the classification of the suborder reconstructed on the basis of inferred relationships. The monophyly of the suborder is supported by two synapomorphies commonly recognized in all included genera. The phylogenetic analysis also revealed support for the suborder by five synapomorphies characterized by reversals or character transformations. In addition, notacanthoids share five apomorphies, present also in Anguilliformes, which may prove to be valid synapomorphies for the former. A phylogenetic analysis based on characters in 30 transformation series resulted in a single most parsimonious tree, which indicated that Aldrovandia branched off initially from other notacanthoids, followed by Lipogenys, and Polyacanthonotus and Notacanthus, which share a sister relationship with each other. Based on the reconstructed relationships, Notacanthoidei is classified into two families, Holasauridae and Notacanthidae, the latter being separated into subfamilies Lipogenyinae and Notacanthinae. Such a classification of Notacanthoidei, recognizing Lipogeninae as a subfamily of Notacanthidae, has not been previously proposed.

Record of a Rare Ophidiid Fish, Barathrites iris (Actinopterygii: Teleostei: Ophidiiformes), from off Southern Japan
OHASHI SHINPEI; IMAMURA HISASHI; YABE MAMORU
Species Divers, 17, 2, 169, 172, Japanese Society of Systematic Zoology, Nov. 2012, [Peer-reviewed]
English, Scientific journal, Two specimens of a rare ophidiid fish, Barathrites iris Zugmayer, 1911, were collected from the abyssal Pacific Ocean, off Kagoshima Prefecture, southern Japan. They agree with the diagnosis of Barathrites in having two pelvic-fin rays, five to six long gill rakers on the anterior gill arch, and a small head (33.5-33.8% of pre-anal-fin length) and eye (1.6-1.8% standard length, SL). Additionally, they can be separated from B. parri Nybelin, 1957, the only other known species of the genus, by their lack of basibranchial tooth patches, smaller eye (10.7-12.3% head length), and shorter pre-dorsal-fin region (17.1-18.9% SL). Previously B. iris was said to differ from B. parri in the number of branchiostegal rays (six versus seven, respectively), but one of the present specimens of B. iris (413mm SL) has seven branchiostegal rays on the left side and six on the right. Earlier workers have suggested the occurrence of Barathrites in the Pacific Ocean, but no documented records from this ocean appear to exist. This study confirms the occurrence of Barathrites and its type species B. iris in the Pacific Ocean.

Species Divers, 17, 2, 145, 150, Japanese Society of Systematic Zoology, Nov. 2012, [Peer-reviewed]
English, Scientific journal, A poorly known scorpionfish (Scorpaenidae), Phenacoscorpius eschmeyeri Parin and Mandrytsa, 1992, has been known only from the holotype from the Sala y Gomez Ridge, southeastern Pacific Ocean. Two new specimens of the species, collected from the Nazca Ridge, near the type locality, and found in the fish collection of the Hokkaido University Museum, are described in detail. The holotype was also reexamined. The two diagnostic characters of the species given in the original description to separate it from a related congener, Phenacoscorpius adenensis Norman, 1939, were found to be invalid, but a new series of diagnostic characters was found. A revised diagnosis of the species is thereupon provided. A color photograph of P. eschmeyeri when fresh is published for the first time.

New Phylogenetic Proposal for the Family Leptoscopidae (Perciformes: Trachinoidei)
ODANI KENJI; IMAMURA HISASHI
北海道大学水産科学研究い報, 61, 2/3, 49, 63, 北海道大学大学院水産科学研究院, Dec. 2011
English, Research institution, Examination of taxa closely related to the family Leptoscopidae resulted in 61 apomorphic characters recognized within the family, based on morphological comparisons with the suborder Percoidei, the following being determined as autapomorphic for the former: U-shaped arrangement of infraorbitals; dermosphenotic fused with sphenotic; laminar process present on dorsalsurface of ethmoid; medially-directed palatine process; and adductor mandibulae section A1 with two tendons inserted laterally and medially onto maxilla. In addition, presence of the rectus dorsalis 3 muscle (rare among Perciformes), is also considered tosupport leptoscopid monophyly. The trachinoid family Creediidae was the inferred sister group of Leptoscopidae, based on the sharing of 43 apomorphies, including two rare perciform characters (absence of pterosphenoid and presence of rectus dorsalis 2). It was also inferred that Leptoscopidae plus Creediidae form a monophyletic group with Trichonotidae and the percophid subfamily Hemerocoetinae, an inference supported by 17 apomorphies, including four rare characters found in only several perciform taxa (ligament present between lower jaw and hyoid arch, ectopterygoid rod-like, ligament present between posttemporal and epiotic, and pelvic bone anterior cartilages fused), although the taxa most closely-related to the group have not yet been determined.

Japanese, Scientific journal, Ninety-nine synaphobranchid specimens, collected from Japanese waters between Hokkaido and Fukushima Prefectures, were identified as Ilyophisnigeli Shcherbachev and Sulak in Sulak and Shcherbachev, 1997 on the basis of the following combination of characters: body scaled; 5 or 6 supraorbital pores; 1or 2 frontal pores; 140-152 total vertebrae; 80-113 total lateral line pores, lateral line ending well anterior to tip of tail; and gill slits horizontal or slightly oblique. Originally described from nine specimens collected from the Pacific slope off Japan, the species, which has been overlooked by Japanese ichthyologists, is redescribed on the basis of the newly-collected specimens. A new standard Japanese name, "Yuki-hora-anago" is proposed for the species.

Japanese, Scientific journal, Twenty specimens of an eelpout, Lycodes uschakovi, were collected from off Monbetsu, north-eastern Hokkaido on the coast of the Okhotsk Sea, and four specimens of Lycodes concolor from around Kitami-Yamato Bank in the Okhotsk Sea. Lycodes uschakovi is characterized by a scaleless belly, submental crests ill-developed and united anteriorly, lateral line mid-lateral in position, and body grey or greyish pink with 8-11 distinct or indistinct transverse white bars extending onto dorsal fin. Lycodes concolor is characterized by 22 pectoral fin rays, scaleless predorsal area, submental crests moderately developed and not united anteriorly, lateral line ventral, distantly spaced neuromasts on the mid-lateral part of the body, body and head uniformly blackish brown, and nostril tube brown. These two species are described in detail and reported as the first records from Japan.

Rediagnosis of the Marbled Flathead, Platycephalus marmoratus (Actinopterygii: Teleostei: Platycephalidae), with Comments on the Composition of the Type Series
IMAMURA HISASHI
Species Divers, 11, 4, 295, 306, Japanese Society of Systematic Zoology, Nov. 2006, [Peer-reviewed]
English, Scientific journal, The taxonomic characters of the marbled flathead, Platycephalus marmoratus Stead, 1908, are described and evaluated. In addition to the marbled body and dark brown to black caudal fin, the following combination of characters separates it from the other 14 species of the genus Platycephalus: 13 second dorsal and anal fin rays; 63-70 scales in the lateral line, with all pored scales lacking spines; snout and interorbit naked; no strong canine teeth on the jaws, palatines, and vomer; interopercular flap absent; and skinny sensory tubes on the suborbitals and preopercle partially covering the cheek region. It has been confirmed that the type series of the species was composed of the holotype and one paratype, although the paratype is presumably no longer extant.

Osteological Description of the Brazilian Flathead, Percophis brasiliensis (Actinopterygii: Perciformes: Percophidae), with Comments on Its Phylogenetic Position
ODANI KENJI; IMAMURA HISASHI; NAKAYA KAZUHIRO
Species Divers, 11, 4, 277, 294, Japanese Society of Systematic Zoology, Nov. 2006, [Peer-reviewed]
English, Scientific journal, Osteological characters of the percophid fish, Percophis brasiliensis Quoy and Gaimard, 1825, the sole member of the subfamily Percophinae, are described in detail. Fifteen apomorphic characters are recognized in this species through morphological comparison with the Percoidei. Of them, the following five characters are determined to be autapomorphic for this species and its subfamily among the Percophidae: urohyal greatly depressed, complex in shape; first pharyngobranchial reduced and completely ossified; Baudelot's ligament branched distally; five supraneurals or ray-less proximal-middle pterygiophores present; and body cavity extending far posteriorly. Percophis brasiliensis is considered to be closely related to the percophid subfamily Bembropinae, because they share three apomorphic characters (presence of a lower backwardly directed opercular spine crossing the subopercle, absence of a tooth plate on the second epibranchial, and absence of supernumerary rays on the ventral portion of the first anal proximal-middle pterygiophore). Although the monophyly of the Percophidae is unconfirmed, because of the lack of plausible synapomorphies, the family is provisionally defined here by the following five apomorphic characters: exoccipital condyles separated in the midline; parasphenoid and pterosphenoid connected; anteroventral portion of second anal proximal pterygiophore with a soft ray; uroneural single; and fewer than 15 branched caudal fin rays present.

Record of the flathead fishes (Perciformes: Platycephalidae) collected from Nha Trang, Vietnam

English, Research institution, The platycephalids collected from Nha Trang, Vietnam were studied taxonomically to record seven species, Elates ransonnetii (Steindachner 1876), Inegocia japonica (Tilesius 1812), Onigocia macrolepis (Bleeker 1854), Platycephalus cultellatus Richardson 1846, Rogadius asper (Cuvier 1829), R. serratus (Cuvier 1829) and R. tuberculatus (Cuvier 1829). Elates ransonnetii and R. serratus are newly recorded from Nha Trang. Platycephalus cultellatus and R. asper have been confused with P. indicus (Linnaeus 1758) and R. pristiger (Cuvier 1829) respectively by many authors and the specimens of P. cultellatus and R. asper represent the reliable first record of these species from Nha Trang. The key characters separating R. asper and R. pristiger are given for the first time. Although the maximum total length of R. tuberculatus was reported to be ca. 14cm, our largest specimen of the species attains ca.18cm.

Phylogenetic Studies of the "Scorpaeniform" Fishes-New Information Since 1998
SHINOHARA GENTO; IMAMURA HISASHI
タクサ, 18, 20, 29, Japanese Society of Systematic Zoology, Feb. 2005, [Peer-reviewed]
Japanese, Scientific journal, An overview of "scorpaeniform" fish phylogenetic studies is presented. Imamura and Shinohara (1998) reviewed previous phylogenetic studies of the "Scorpaeniformes" and stated that monophyly was unlikely. Since 1998, 4 papers (1 morphological and 3 molecular) have been published, which independently show the polyphyletic origins of this group. The present paper provides an outline of Imamura and Shinohara's (1998) paper, and gives summaries of the 4 subsequent papers. Evidence for polyphyly presented in the 4 papers is discussed. Suggestions for future areas of "scorpaeniform" taxonomic and evolutionary research are presented.

A taxonomic examination of 3,108 specimens of mesopelagic fishes, collected around the Ogasawara Islands in December 2010 by a beam trawl net operated from the T/S Oshoro-maru, Hokkaido University, Japan, resulted in the recognition of 99 species representing 34 families and 65 genera. Descriptions are provided for all species, two of them〔 a stomiid Eustomias braueri Zugmayer, 1911 and linophrynid Haplophryne mollis (Brauer, 1902)〕 being new records for Japan. Three species, a stomiid Eustomias sp., trachipterid Desmodema sp. and oneirodid Oneirodes sp., could not be identified at the species level., Faculty of Fisheries Sciences, Hokkaido University, English, Introduction research institution

IMAMURA Hisashi, Species Diversity, 8, 3, 301, 306, 31 Aug. 2003
The genus Sunagocia is established as a replacement name for the platycephalid fish genus Eurycephalus Imamura, 1996, which is preoccupied by the cerambycid beetle genus Eurycephalus Gray in Cuvier and Griffith, 1832. The genus currently contains three valid species : S. arenicola (Schultz, 1966), comb, nov., S. carbunculus (Valenciennes in Cuvier and Valenciennes, 1833), comb, nov., and S. otaitensis (Cuvier in Cuvier and Valenciennes, 1829), comb. nov. It is confirmed that Cuvier satisfied the nomenclatural requirements for availability of this last species, although several investigators have attributed the name to Parkinson, who made the unpublished drawing of S. otaitensis used in its original description and named the species. Two measurements, of head length and especially interorbital width, are helpful in distinguishing S. carbunculus, S. arenicola, and S. otaitensis from each other., Japanese Society of Systematic Zoology, English

Record of a sandperch, Parapercis xanthozona (Actinopterygii: Pinguipedidae), from Japan, with Comments on its Synonymy
IMAMURA Hisashi; MATSUURA Keiichi, Species Diversity, 8, 1, 27, 33, 01 Feb. 2003
Six specimens of the pinguipedid fish Parapercis xanthozona (Bleeker, 1849) were collected from Amami-Oshima Island of the Ryukyu Islands in 1991 and 1994. This represents the first reliable record of the species from Japan. It is concluded that Percis pleurostigma Sauvage, 1891, which had been considered conspecific with P. xanthozona, is a junior synonym of Parapercis punctulata (Cuvier in Cuvier and Valenciennes, 1829). We concur with synonymizing Parapercis dorsonebulosa Martin and Montalban, 1935 with P. xanthozona ; this synonymy has been overlooked since 1951., Japanese Society of Systematic Zoology, English

魚類の中で最も多様に種分化したのは鰭に棘をもつグループであるが、棘の役割については十分に調べられてはこなかった。本研究では、国内外の研究機関から多くの標本を集め、解剖やエックス線撮影から臀鰭の棘の形状を調べ、一部の種でこれまで考慮されたことのないセンサーの役割の可能性があることを示した。異なった魚種間で鰭の構成要素の並び方や数を簡単に比較できる方法を開発し、分類や進化の研究を推進する基礎を作った。

Ecological Studies on Crossbreeding among Hexagrammos Species
Grants-in-Aid for Scientific Research
2004 - 2006

In hexagramids, one boreal species (Hexagrammos octogrammus) and two temperate species (H.otakii and H.agrammus) are distributed in the coast of Japan, and crossbreeding among the three species is known to occur. This study was conducted to clarify what ecological factors involve in the crossbreeding.
1.The preference of spawning substratum differed among the three species. In natural habitats, H.otakii occurred deeper than the other two species which preferred to seaweed. On the other hand, the three species established concurrently their breeding territory in the artificial area.
2.H.octogrammus females were observed in the spawning area of H.otakii on breaker zone, and hybrids were often observed near the artificial fish reefs. It was possible to discriminate visually the eggs of H.otakii from the other two species because of difference of egg-coloration. Several egg masses of H.octogrammus or H.agrammus were often deposited in the H.otakii terrirories.
3.Polymorphism of mtDNA enables to discriminate what species deposited the egg masses in the territory of H.otakii. 40% of the egg masses deposited in H.otakii territories was crossbreeding, and mother of all of them was H.octogrammus. 1.9% of the egg masses in H.agrammus territories were deposited by H.octogrammus. No eggs of H.otakii were observed in the other species territory. This uni-direction hybridization showed that gene introgression from H.octogrammus into H.otakii is proceeding through crossbreeding.
4.80 individuals of hybrid and backcross were collected during this study. Sex of all the fishes was female. To clarify this sexual bias FISH method and survival experiments of embryos were conducted. FISH method denied a possible of gynogenesis of hybrid, and there was no significant difference the survival rates of between purebred embryos and crossbred ones. These results suggested that genetic males exist at least just after hatching.
