Abstract

Oligosarcus amome is described from tributaries of the arroyo Yabotí-Guazú, río Uruguay basin, Misiones Province, Argentina. This new species can be distinguished from all its congeners by the following combination of characters: presence of two conspicuous series of teeth on premaxilla bearing pentacuspidate teeth in the outer series. Oligosarcus amome is the sister taxon of all remaining analyzed species of the genus excepting O. itau.

摘要

奥氏寡脂鲤（Oligosarcus amome）是在阿根廷米西奥内斯省乌拉圭河流域亚博蒂 - 瓜苏河（arroyo Yabotí-Guazú）支流中被描述的。这个新物种可以通过以下特征组合与所有同属物种区分开来：前上颌骨上有两排明显的牙齿，外侧一排为五尖齿。奥氏寡脂鲤是该属所有其余分析物种（除伊塔乌寡脂鲤（O. itau）外）的姐妹分类单元。
