摘要

本文报道了新世界链翅目，1793年蛛属(蛛科)两新种。两者都是Mischocyttarus Saussure, 1853(寄生蜂科:Mischocyttarini)的社会黄蜂的内寄生虫。双色Xenos Benda & Straka, sp. nov寄生于Mischocyttarus navajo Bequaert, 1933, Mischocyttarus flavitarsis (Saussure, 1854)和Mischocyttarus pallidipectus (Smith, 1857)，而淡色Xenos Benda & Straka, sp. nov是Mischocyttarus costaricensis Richards, 1945 (Vespidae: Polistinae: Mischocyttarini)的寄生虫。本文介绍了寄生于Mischocyttarus物种的所有三种雌性头胸的诊断和描述。本文介绍了双色和淡色异头蝇的雄性头蝇科的诊断和描述，并根据雌性头胸和雄性头蝇的特征，给出了寄生在Mischocyttarus上的异头蝇属的关键。讨论了基于外部形态的Xenos物种鉴定。

Two new species of Xenos (Strepsiptera: Xenidae), parasites of social wasps of the genus Mischocyttarus (Hymenoptera: Vespidae) in the New World

Two new species of Strepsiptera of the genus Xenos Rossi, 1793 (Xenidae) from the New World are described. Both are endoparasites of social wasps of the genus Mischocyttarus Saussure, 1853 (Vespidae: Mischocyttarini). Xenos bicolor Benda & Straka, sp. nov., parasitizes Mischocyttarus navajo Bequaert, 1933, Mischocyttarus flavitarsis (Saussure, 1854), and Mischocyttarus pallidipectus (Smith, 1857), whereas Xenos pallens Benda & Straka, sp. nov., is a parasite of Mischocyttarus costaricensis Richards, 1945 (Vespidae: Polistinae: Mischocyttarini). Diagnoses and descriptions of female cephalothoraces are presented for all three species that parasitize species of Mischocyttarus. Diagnoses and descriptions of male cephalothecae are presented for Xenos bicolor sp. nov. and Xenos pallens sp. nov. Additionally, a key for Xenos species parasitic on Mischocyttarus is provided based on characters of the female cephalothorax and male cephalotheca. Identification of Xenos species based on external morphology is discussed.
