Abstract

A new species of Knodus is described from the rio Cupari drainage, a tributary from the right margin of the lower rio Tapajós, Pará State, Brazil. The new species differs from its congeners, except K. geryi, by having a dark basal blotch on each caudal fin lobe (vs. caudal fin lobes with sparse chromatophores, lacking basal blotches) and, with the exception of K. borki, K. heteresthes, and K. pasco, by having 10-12 scales around the caudal peduncle (vs. 13-15).

摘要

一种新的克诺德氏鱼（Knodus）被描述于巴西帕拉州下塔帕若斯河右岸支流库帕里河排水区。该新物种与其同属物种不同，除了格雷氏克诺德氏鱼（K. geryi）外，其尾鳍各叶上有一个深色基部斑点（与之相比，其他同属物种尾鳍叶上色素细胞稀疏，无基部斑点）；并且，除了博尔基克诺德氏鱼（K. borki）、赫特斯氏克诺德氏鱼（K. heteresthes）和帕斯科克诺德氏鱼（K. pasco）外，其尾柄周围有10 - 12枚鳞片（与之相比，其他同属物种为13 - 15枚）。
