Fissarcturus bathyweddellensis sp. nov. and Fissarcturus sandwichi sp. nov. are described from the abyssal Southern Ocean near the Antarctic Peninsula and Fissarcturus rossi sp. nov. is described from the shallow Ross Sea. A list of all described species of Fissarcturus is given. The new species differ from recognized species of the genus in the following respects: F. bathyweddellensis can be distinguished based on spination on the dorsum of the body, which is described in detail herein. It is most similar to F. emarginatus Brandt, 1990, but this has, for example, a shorter and less stout second cephalic spine. F. rossi can also be distinguished from F. bathyweddellensis based on spine pattern. Whereas all dorsal spines of F. bathyweddellensis are smooth, those of F. rossi are covered with spinules. F. sandwichi can be distinguished from the other species of the genus by the strong frontally bent supraocular spines (females with second cephalic spines) and dorsal body surface, which is covered with flat, cauliflower-like elevations in submedial, lateral and coxal rows.  © 2007 The Linnean Society of London, Zoological Journal of the Linnean Society , 2007, 149 , 263–290.  相似文献

A new genus Dimorphacanthella is established for Tetracanthella anommatos Chen and Yin, 1984 and Dimorphacanthella mediasetasp. n. from China. The new genus exhibits an unusual metamorphosis: small juveniles, previously called Uzelia anommatos Yue & Yin, 1999 get the second pair of anal spines resulted from moulting and become "Tetracanthella". Species identity of forms with two and four anal spines is proved by barcoding analysis. The derivation of anal spines is compared among genera having four anal spines.  相似文献

A new cottid species,Icelus ecornis, is described on the basis of 31 specimens collected from 159–226 m in the southwestern Okhotsk Sea off Hokkaido, Japan. It is distinguished from all other members of the genusIcelus by the following combination of characters: no supraocular and parietal spines; short blunt nuchal spine; cirri absent from head and body, except for supraocular, parietal and nuchal regions; platelike scales of dorsal row bearing 6–10 long uniform spinules; tubular lateral line scales bearing small spines on dorsal and posterior margins; large oval black spot on first dorsal fin; 16–20 anal fin rays.  相似文献

A rare platycephalid,Onigocia grandisquama (Regan), is redescribed in detail from the holotype and an additional specimen collected from the Gulf of Thailand, western Pacific. The species is characterized by the following combination of characters: 11 anal fin rays, 32–34 lateral line scales, anteriormost 3–5 or 3–6 lateral line scales with a distinct spine, 1–2 preocular spines, broad and flat ocular flap, and long head (42.4–44.7% of standard length).  相似文献

Alectrias mutsuensis sp. nov. is described on specimens collected from Mutsu Bay, Aomori Pref. This new species is rather deep dweller compared to other species of the genus, living on muddy bottoms, about 20 to 40 meters deep, and is diagnosed by the following characters: dermal crest on head reaching to occipital region; distance between end of dermal crest and dorsal fin origin less than eye diameter; end of anal fin separated from caudal fin; anterior dorsal spines before anal origin, slender and flexible; epaxial hypurals mostly fused into a single plate. A key to all nine species belonging to the subfamily Alectriinae is presented.  相似文献

Neolumpenus unocellatus gen. et sp. nov., a stichaeid fish (subfamily Lumpeninae,sensu Makushok, 1958) is described on the basis of a single specimen found in the stomach of the Pacific cod,Gadus macrocephalus Tilesius, caught off Akkeshi, Hokkaido, Japan. The new genus and species is distinguished from all other lumpenines in having the following combination of characters: 1) 51 dorsal spines, 33 anal fin rays, 57 total vertebrae; 2) broad pelvic fin with deeply-branched soft rays; 3) lower rays of pectoral fin branched and not prolonged backward; 4) prevomerine and palatine teeth present; 5) pungent spines present in pelvic and anal fins; 6) upper lip fused to snout anteriorly; 7) gill openings not extending forward beyond a vertical through posterior margin of eye; 8) minimal (fifth) hypural present; 9) first interneural spine inserted between first and second neural spines; 10) extremely large cephalic sensory pores present; 11) high, steep snout; 12) ocellus on dorsal base of caudal fin.  相似文献

在对分布于中国的蝴蝶鱼科鱼类进行系统分类时,通过形态特征的比较分析,发现了蝴蝶鱼科的一个中国新记录种——多棘马夫鱼(Heniochus diphreutes Jordan)。新记录种与近缘种马夫鱼[H.acuminatus (Linnaeus)]的主要区别为:背鳍鳍棘Ⅻ对Ⅺ;上下颌齿2~3排对5~7排;头部腹侧较圆钝对较平直;臀鳍较尖锐对较圆钝;臀鳍后部黑色横带向前延伸至最长鳍条,对未向前延伸至最长鳍条;吻长较短且小于眼径,对吻长较长且大于眼径。  相似文献

记比耶鱼(Birgeria)在中国的首次发现   总被引:4,自引:0,他引:4

记述了采自云南罗平晚三叠世法郎组竹杆坡段的比耶鱼一新种──刘氏比耶鱼(Birgeria liui sp. nov.),这是比耶鱼化石在中国的首次发现。刘氏比耶鱼与产自瑞士圣乔治山中三叠世边境沥青层的史氏比耶鱼最为相近,两者仅在尾柄长高之比、尾鳍长短与上下叶外缘交角、背鳍和臀鳍辐状支鳍骨的数目、臀鳍辐状骨骨板的大小、以及侧线管骨化与否等特征上略有差异。比耶鱼与软骨硬鳞鱼超目的鲟形目最为接近,两者共有一系列特征,如除尾上叶外体侧裸露,副蝶骨末端伸达头后,鳃盖骨退化;但比耶鱼同时也具有不少的特有特征,代表了软骨硬鳞鱼超目的另一类群──比耶鱼目(Birgeriiformes ord. nov.)。刘氏比耶鱼的发现进一步表明华南扬子区中、晚三叠世鱼类化石与特提斯西部的鱼群具有密切的动物地理关系。  相似文献
