宽鳃鮟鱇属一新种

A NEW SPECIES OF THE GENUS SLADENIA (PISCES, LOPHIIDAE)FROM THE EAST CHINA SEA AND THE SOUTH CHINA SEA

20世纪70年代以前,全世界已知宽鳃鮟鱇属Sladenia Regan(1908)鱼类仅有3种。1980～1982年期间,东海水产研究所"东方"号和南海水产研究所"南锋"号调查船分别在东海和南海的大陆架渔场调查时,共采集到4尾珍稀的深海鮟鱇鱼类。经研究,认为这4尾标本是1新种,定名为朱氏宽鳃鮟鱇Sladenia zhui sp.nov.。

A new lophiid anglerfish of the deep water genus Sladenia is described based on four specimens collected from the East China Sea and the South China Sea during the period from 1980 to 1982. Sladenia Regan （1908） is a genus of lophiid anglerfish with rounded rather than depressed head, and compressed rather than depressed tail; nasal sacs not constricted at the base; very long pseudobranchia; humeral, subopercular, quadrate, parietal and articular spines absent; epiotic and interopercular spines low and rounded; vomerine teeth larger than palatine teeth; illicial bone and second dorsal spine inserting very close together on illicial pterygiophore; third or third and fourth dorsal spines invisible, hiding under the skin of post-cephalic portion; and smooth ridge on frontal bones anterior to eyes and lateral to illicial pterygiophore. There were only four specimens, identified as 3 species, i. e., S. gardineri Regan, 1908, S. remiger Smith et Radcliffe, 1912 and S. shaefersi Caruso et Bullis 1976, belonging to the genus Sladenia in the world before 1976. During the period from 1980 to 1982, the RV ＂Dongfang＂ and the RV ＂Nanfeng＂ of the East China Sea Fisheries Institute and the South China Sea Fisheries Research Institute respectively, completed a survey of the deep water fish fauna of the East and South China Seas. Four separate Chinese specimens of the rare lophiid anglerfish genus Sladenia were collected. With detailed analysis of the four rare specimens, it was recognized that they should belong to the same species, and also a new species named as Sladenia zhui.
