Revision of the <em>Calotheca nigrotessellata</em> species group from southern Africa, with description of two new species (Coleoptera: Chrysomelidae, Galerucinae, Alticini)
Calotheca Heyden is a mostly sub-Saharan flea beetle genus, comprising twenty-seven species previously included in Blepharida Chevrolat. The examination of new material is revealing a high species richness, as there is high intraspecific variability. Calotheca luteomaculata sp. nov. from Zimbabwe a...
