Abstract

Twelve new species of Bibrax Fletcher, 1927 (Coleoptera: Staphylinidae: Pselaphinae: Euplectitae: Metopiasini) from Ecuador are described: B. chullachaqui sp. nov., B. chocoensis sp. nov., B. onorei sp. nov., B. aratrifer sp. nov., B. longiventer sp. nov., B. cerroblanco sp. nov., B. canelazo sp. nov., B. pectinifer sp. nov., B. arachnoides sp. nov., B. amasanga sp. nov., B. yasuni sp. nov., and B. grandis sp. nov. A key for all species of Bibrax is provided. These are the first records of the genus for the country, and we report species from most major environments in the country, from seasonal coastal forests to cloud forests and the Amazonian Basin. The new species expand the scope of morphological variability in the genus, with discovery of numerous microphthalmous and wingless species, and a range of previously unreported secondary sexual characters. Most of the species are only known from single localities, suggesting a large fauna remaining to be discovered from a large portion of South America.

First厄瓜多尔Bibrax Fletcher记录，1927（鞘翅目，棘蝇科，棘蝇科），附12新种描述。

本文描述了厄瓜多尔Bibrax Fletcher， 1927年的12个新种（鞘翅目：葡萄球菌科：棘蚜科：蠓科：拟蠓科：Metopiasini）： B. chullachaqui sp. nov、B. chocoensis sp. nov、B. onorei sp. nov、B. aratrifer sp. nov、B. longiventer sp. nov、B. cerroblanco sp. nov、B. canelazo sp. nov、B. pectinifer sp. nov、B. arachnoides sp. nov、B. amasanga sp. nov、B. yasuni sp. nov和B. grandis sp. nov。这是该属在该国的第一次记录，我们报告了该国大多数主要环境中的物种，从季节性沿海森林到云雾林和亚马逊盆地。新物种扩大了该属的形态变异范围，发现了许多小眼和无翅物种，以及一系列以前未报道的第二性征。大多数物种只在一个地方被发现，这表明在南美洲的大部分地区仍有大量的动物群有待发现。
