Abstract

A taxonomic revision of the Afrotropical genus Zetheumenidion Bequaert, 1926 is presented. Four new species (Zetheumenidion abruptum sp. nov., Zetheumenidion concinnoide sp. nov., Zetheumenidion latum sp. nov. and Zetheumenidion minimum sp. nov.) are described; Zetheumenidion paeneplanum (Bequaert, 1926) stat. rev. is resurrected from synonymy with Z. pulchripenne (Cameron, 1910); Zetheumenidion femoratum flavissimum Giordani Soika, 1987 is raised to species level (Zetheumenidion flavissimum stat. nov.). A key to all known species is provided and the taxonomic placement of the genus is discussed.

摘要

本文对 1926 年由 Bequaert 建立的非洲球甲属 Zetheumenidion 进行了分类修订。描述了 4 个新种（Zetheumenidion abruptum sp. nov.，Zetheumenidion concinnoide sp. nov.，Zetheumenidion latum sp. nov. 和 Zetheumenidion minimum sp. nov.）；将 Zetheumenidion paeneplanum (Bequaert, 1926) stat. rev. 从 Z. pulchripenne (Cameron, 1910) 的同物异名中恢复；将 Giordani Soika, 1987 建立的 Zetheumenidion femoratum flavissimum 提升为种级（Zetheumenidion flavissimum stat. nov.）。提供了所有已知种的关键特征，并讨论了该属的分类位置。
