Schistura paraxena, new species, is described from the Pearl River drainage in Laibin, Guangxi Province, China. The new species is easily distinguished from its congeners in having conspicuous peduncular crests along its dorsal and ventral extremities and a plain beige body coloration with crests brownish gray and a pale spot medially at caudal-fin base. Further characters useful to diagnose the species, but not unique to it, are: 8½ branched dorsal-fin rays; 11-12 pectoral-fin and 9 pelvic-fin rays; modally 38 vertebrae; predorsal length 50-52% SL; caudal-peduncle length 17-18% SL (88-92% HL; 5.6-5.8 times SL); lateral line complete; breast naked; predorsal area scaled; and upper lip not notched.
拟近原吸鳅,新物种,采自中国广西来宾珠江水系。该新物种易于与其同属物种区分,其背、腹缘具明显的柄部嵴,体色呈浅米色,嵴为褐灰色,尾鳍基部中央有一浅色斑点。其他有助于鉴别该物种但并非其独有的特征包括:背鳍分枝鳍条8½;胸鳍鳍条11 - 12,腹鳍鳍条9;脊椎骨通常为38枚;背前长为标准体长的50 - 52%;尾柄长为标准体长的17 - 18%(为头长的88 - 92%;为标准体长的5.6 - 5.8倍);侧线完整;胸部裸露;背前部被鳞;上唇无缺刻。
