Abstract

A new species of Cetopsorhamdia is described from material collected on rapid inventories and ichthyological expeditions in the Amazon region of Peru, Ecuador and Colombia. The new species can be differentiated from all other species of Cetopsorhamdia by the colouration pattern on fins, number of vertebrae, number of ribs, level insertion of dorsal fin, number of rays on dorsal and pectoral fin, osteological characters and several other morphometric characters. The new species is distributed along tributaries of the upper Amazon River basin in Peru, Colombia and Ecuador.

摘要

一种新的 Cetopsorhamdia 物种是根据在秘鲁、厄瓜多尔和哥伦比亚亚马逊地区的快速清查和鱼类学考察中收集的材料描述的。新物种可以通过鳍的颜色模式、椎骨数量、肋骨数量、背鳍的插入水平、背鳍和胸鳍的射线数量、骨骼特征和其他几个形态特征与 Cetopsorhamdia 的所有其他物种区分开来。新物种分布在秘鲁、哥伦比亚和厄瓜多尔的亚马逊河流域上游的支流中。
