Abstract

In the present communication a new glyptosternine catfish Creteuchiloglanis nuthemuensis, is described from the Duphlokho River in West Kameng district, Arunachal Pradesh, India, which is a headwater of the Kameng River in the Brahmaputra basin. The new species is eminent from all closely related species of the genus by a distinct combination of the subsequent characteristics: presence of long pectoral fin extending over the pelvic fin origin and its reaching posterior end of dorsal fin base, body depth at anus 12–15.8% SL, predorsal length 34.5–35.9% SL, pelvic fin length 16–19.8% SL, adipose fin base length 28.3–33.3% SL, caudal peduncle depth 6.6–7.6% SL, absence of pinnate-like rays on the first branching ray’s anterior margin and second simple ray of anal fin, head depth 9.9–11.3% SL, and eye diameter 5.3–7.5% HL. This is the sixth Creteuchiloglanis species described from the Brahmaputra River basin.

摘要

在本通报中，描述了一种新的光胸鲶鱼Creteuchiloglanis nuthemuensis，产自印度阿鲁纳恰尔邦西卡门县的杜弗洛科河，该河是雅鲁藏布江盆地卡门河的源头。该新物种通过以下特征的独特组合而从该属所有密切相关的物种中脱颖而出：长胸鳍延伸超过腹鳍起点并到达背鳍基部的后端，肛门处的体深为12-15.8 % SL，前背长度 34.5–35.9% SL，腹鳍长度 16–19.8% SL，脂鳍基部长度 28.3–33.3% SL，尾柄深度 6.6–7.6% SL，第一条分支鳍条上没有羽状鳍条臀鳍前缘和第二单鳍条，头部深度 9.9–11.3% SL，眼直径 5.3–7.5% HL。这是雅鲁藏布江流域描述的第六个Creteuchiloglanis物种。
