Abstract

A new genus, Coleotestudus gen. nov., is proposed for the North American species currently placed in the genus Niptus Boieldieu and are transferred herein. Those species with this new combination include Coleotestudus ventriculus (LeConte), Coleotestudus guiliani (Aalbu and Andrews), Coleotestudus sleeperi (Aalbu and Andrews), Coleotestudus abditus (Brown), Coleotestudus arcanus (Aalbu and Andrews), Coleotestudus neotomae (Aalbu and Andrews), Coleotestudus absconditus (Spilman), and Coleotestudus abstrusus (Spilman). Two new species from Mexico are also described as Coleotestudus potosi sp. nov. and Coleotestudus nahuas sp. nov. Distinguishing morphological characteristics to separate the North American Coleotestudus species from Niptus hololeucus are given. Morphological evidence presented herein along with DNA sequence data and a Western USA and Mexican distribution strongly support the hypothesis that Coleotestudus does not share a recent common ancestor with N. hololeucus and both represent independent clades of spider beetles that are not closely related.

Coleotestudus:北美Niptus属新属(鞘翅目:虻科)和墨西哥两新种描述

一个新的属，Coleotestudus gen. nov.，提出了目前在Niptus Boieldieu属的北美物种，并转移到这里。具有这种新组合的物种包括:脑室Coleotestudus (LeConte)、吉利Coleotestudus (Aalbu和Andrews)、睡眠Coleotestudus (Aalbu和Andrews)、abditus (Brown)、arcanus (Aalbu和Andrews)、neotomae Coleotestudus (Aalbu和Andrews)、潜行Coleotestudus (Spilman)和精深Coleotestudus abstrusus (Spilman)。本文还给出了两个墨西哥新种Coleotestudus potosi sp. 11和Coleotestudus nahuas sp. 11，并给出了北美Coleotestudus种与Niptus hololeucus的区分形态学特征。本文提出的形态学证据、DNA序列数据以及美国西部和墨西哥的分布都有力地支持了Coleotestudus与N. hololeucus没有共同祖先的假设，它们都代表了蜘蛛甲虫的独立分支，但并不密切相关。
