Taxonomic revision of the genus Casphalia Walker, 1866 (Lepidoptera, Limacodidae: Limacodinae)

This paper presents the first comprehensive revision of the Afrotropical genus Casphalia Walker, 1866. Through the utilisation of integrative taxonomic methods (external morphology, dissections of genitalia and DNA barcoding), we distinguish two species groups—C. flavicollis species group and the C. nigerrima species group—within the genus and herein describe 7 new species: C. tabererae sp. nov., C. kerkhofi sp. nov., C. hanoti sp. nov., C. fredpricei sp. nov., C. kambama sp. nov., C. inlenis sp. nov. and C. clara sp. nov. Erotomania Hering, 1930 is synonymezid with Casphalia and several new taxonomic combinations are proposed: Erotomania schoutedeni Hering, 1930 is transferred to Casphalia (Casphalia schoutedeni (Hering, 1930) comb. nov.) and Casphalia citrimaculata Aurivillius, 1905 is synonymised with Eccopa oculita Karsch, 1899 syn. n. The adults and genitalia of all taxa, their habitats and distribution are illustrated in 180 colour figures and three distribution maps.
