Abstract

Calotheca Heyden, 1887 is a flea beetle genus that occurs predominantly in sub-Saharan Africa, comprising 29 species. The examination of new material is revealing a significantly higher species richness and high intraspecific variability. A group of five species, occurring in the southernmost portion of the distribution range for the genus, is here attributed to the C. parvula species group: C. parvula (Weise, 1908), C. pallida (Bryant, 1945), C. danielssoni sp. nov., C. oberprieleri sp. nov., and C. prinslooi sp. nov. Species in the C. parvula group have strong similarities in body shape and sculpture on the integument, spermathecal shape, and for most species the morphology of the median lobe of the aedeagus. A key to species of the Calotheca parvula group is provided along with photographs of the habitus, main diagnostic characters, median lobe of the aedeagus and spermatheca. In addition to the geographic distribution, the available information on the habitat, host plants, and phenology are provided for the five species analysed.

南部非洲小花蝉(Calotheca parvula)种群的分类学修订，附三新种记述(鞘翅目，金蝶科)

Calotheca Heyden, 1887是一种跳蚤甲虫属，主要分布在撒哈拉以南非洲，由29种组成。对新材料的研究显示出明显更高的物种丰富度和高种内变异性。出现在该属分布范围最南端的一组五种被归为C. parvula种组:C. parvula (Weise, 1908)， C. pallida (Bryant, 1945)， C. danielssoni sp. nov.， C. oberprieleri sp. nov.和C. prinslooi sp. nov.。C. parvula组中的物种在身体形状和被盖上的雕塑，精囊形状，以及大多数物种的aedeagus中间叶的形态上具有很强的相似性。本文还提供了一份小孔蝶群的物种分类表，并附有其习性、主要诊断特征、翅正中叶和精囊的照片。除了地理分布外，还提供了所分析的五个物种的栖息地、寄主植物和物候的现有信息。

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.
