摘要
为了容纳来自南非共和国和刚果民主共和国的Cercyon (Acycreon) pulsatus d 'Orchymont, 1937，本文描述了一种新属，Evanesternum gen. n.(亲水科:球形甲虫科:Megasternini)。详细的描述提供了相关诊断特征的习性照片、线条图和扫描电镜显微照片。新属具有Megasternini的部落近亲，但具有几个独特的形态特征，并对其进行了详细讨论。本文对1942年被分类为Acycreon d’orchymont亚属的其余三个物种(即C. punctiger Knisch, 1921, C. collarti d’orchymont, 1942和C. apiciflavus Hebauer, 2002)的形态进行了说明，以证明Acycreon是一个形态不同且可能不相关的物种组合。一个鉴定钥匙的Megasternini属和亚属已知从南非共和国提出。
A new genus of coprophagous water scavenger beetle from Africa (Coleoptera, Hydrophilidae, Sphaeridiinae, Megasternini) with a discussion on the Cercyon subgenus Acycreon
A new genus of coprophagous beetle, Evanesternum gen. n. (Hydrophilidae: Sphaeridiinae: Megasternini), is described in order to accommodate Cercyon (Acycreon) pulsatus d’Orchymont, 1937 from the Republic of South Africa and the Democratic Republic of Congo. A detailed description is provided along with habitus photographs, line drawings and SEM micrographs of relevant diagnostic characters. The new genus possesses the tribal synapomorphies of Megasternini but bears several unique morphological characters which are discussed in detail. The morphology of the remaining three species classified in the subgenus Acycreon d’Orchymont, 1942 (i.e. C. punctiger Knisch, 1921, C. collarti d’Orchymont, 1942 and C. apiciflavus Hebauer, 2002), is illustrated in order to provide evidence that Acycreon is an assemblage of morphologically dissimilar and likely not related species. An identification key to the Megasternini genera and subgenera known from the Republic of South Africa is presented.
期刊介绍：
African Invertebrates is an international peer-reviewed, open-access journal that focuses primarily on the taxonomy, systematics, biogeography, and palaeontology of Afrotropical invertebrates, whether terrestrial, freshwater or marine. Aspects concerning biology, ecology, and conservation may also be considered where these relate to the primary focus areas. Papers dealing solely with biology, ecology, physiology, pests and pest control should be submitted elsewhere.
