Abstract

Olixon Cameron, 1887 is a genus of solitary wasps belonging to Rhopalosomatidae with 28 species worldwide, all of which are distinct being brachypterous and having the inner eye margins straight. In this paper, we describe Olixon pantanensis Bulbol, Bartholomay & Somavilla sp. nov., based on a male from the Brazilian Pantanal biome and provide new distribution records for O. testaceum Cameron, 1887 in the country. We also provide the first descriptions and illustrations of the male genitalia for both species.

摘要

奥利克森黄蜂属（Olixon）于1887年被确立，是胡蜂科（Rhopalosomatidae）的一类独居黄蜂，全球共有28个物种，它们均有短翅，内眼缘笔直，形态各异。在本文中，我们基于一只来自巴西潘塔纳尔生物群落的雄性黄蜂，描述了新物种潘塔纳尔奥利克森黄蜂（Olixon pantanensis Bulbol, Bartholomay & Somavilla sp. nov.），并给出了1887年描述的黄褐奥利克森黄蜂（O. testaceum Cameron）在该国的新分布记录。我们还首次描述并绘制了这两个物种雄性生殖器的图谱。
