Revision of the southern African genera Nemopterella Banks and Nemia Navás (Neuroptera: Nemopteridae: Nemopterinae), with descriptions of new genera and species.

The southern African genera Nemopterella Banks, 1910 and Nemia Navás, 1915 (Neuroptera: Nemopteridae: Nemopterinae) are revised. Nemopterella is split into three genera: Nemopterella sensu stricto with type species Nemopteryx africana Leach, 1815 (= Nemopterella africana), Afroptera gen. nov., with type species Nemopterella munroi Tjeder, 1967, and the monotypic genus Siccanda gen. nov., with type species Nemopterella arenaria Tjeder, 1967. Eight new species are described in Afroptera gen. nov.: A. acuta Abdalla Mansell sp. nov., A. alba Mansell Abdalla sp. nov., A. brinkmani Abdalla Mansell sp. nov., A. balli Abdalla Mansell sp. nov., A. cylindrata Abdalla Mansell sp. nov., A. folia Abdalla Mansell sp. nov., A. koranna Mansell Abdalla sp. nov., A. maraisi Abdalla Mansell sp. nov., as well as two new species in the genus Nemopterella: N. kabas Mansell Abdalla sp. nov., and N.cedrus Mansell Abdalla sp. nov.

An update to the taxonomy of the genus Macroderes Westwood 1842 (Coleoptera: Scarabaeidae: Scarabaeinae) with descriptions of new species from South Africa.

The genus Macroderes Westwood, 1842 (Scarabaeidae: Scarabaeinae, tribe incertae sedis) is practically endemic to South Africa with only one species that is found little north in southern Namibia. The ranges of the species are limited to the winter-fall and bimodal biomes of South Africa comprising the regions of Richtersveld as extreme points of its northerly distribution, and extending to the south through Namaqualand to Cape Agulhas. The taxonomy of the genus is revised. Fourteen valid species are recognised and three others are of doubtful validity. Seven new species are described, these are: M. cederbergensis Abdalla Deschodt, new species, M. tortuosus Abdalla Scholtz, new species, M. gifboomi Abdalla Scholtz, new species, M. leipoldti Abdalla Deschodt, new species, M. oreatus Abdalla Deschodt, new species, M. porselinus Abdalla, new species, and M. soleiana Abdalla Deschodt, new species. Macroderes nitidus Harold, 1877 is redescribed and its lectotype is designated. The diagnostic characters as well as an updated geographic distribution of each species are summarised. An updated key of the genus, photographs of habitus, sclerites of internal sac, pronotum, pronotal punctures and elytra also are provided.
