摘要

描述了巴西帕拉州圭亚那地盾区下游亚马逊盆地Rio Paru do Oeste（Rio Trombetas盆地）支流Hyphessobrycon的一个新种。新物种呈现出一种独特的组合，包括不规则形状的肱骨斑点、宽的弥漫性中侧条纹和大致三角形的尾柄斑点。本文将该新物种纳入Hyphessobrycon agulha物种群，并将其与属于该群的物种以及长相相似的非同源物种——贝洛蒂半球赤眼蜂进行了比较。

A New Hyphessobrycon (Characiformes: Characidae) from the Guiana Shield in Northern Brazil

A new species of Hyphessobrycon from a tributary of the Rio Paru do Oeste (Rio Trombetas basin), at the lower Amazon basin draining the Guiana Shield region in Pará State, Brazil, is described. The new species presents a unique combination of an irregularly-shaped humeral blotch, a broad diffuse midlateral stripe, and a roughly triangular caudal peduncle blotch. The new species is herein included in the Hyphessobrycon agulha species-group, and comparisons with species belonging to this group and to a similar-looking non-congener, Hemigrammus bellottii, are presented.

期刊介绍： Founded in 1913, Copeia is a highly respected international journal dedicated to the publication of high quality, original research papers on the behavior, conservation, ecology, genetics, morphology, evolution, physiology, systematics and taxonomy of extant and extinct fishes, amphibians, and reptiles. Copeia is published electronically and is available through BioOne. Articles are published online first, and print issues appear four times per year. In addition to research articles, Copeia publishes invited review papers, book reviews, and compiles virtual issues on topics of interest drawn from papers previously published in the journal.
