Re-defined Aparopionella from Afrotropical forest floors comprises 20 poorly known nominal species (Coleoptera, Curculionidae, Molytinae)

摘要

The presumed monophyletic molytine genus Aparopionella Hustache, 1939 is re-defined to embrace 20 Afrotropical nominal species distributed between Kenya and the Republic of South Africa. No new species are here described, although dozens of candidatespecies have been sampled, mainly from Tanzania. Three genus-group names are synonymized under Aparopionella: Adichotrachelus Hoffmann, 1965 syn. n., Merunymus Hoffmann, 1965 n. syn. and Orinanchonus Voss, 1965 n. syn. Two subspecies are raised to full species status under Aparopionella: hanangensis Voss, 1965, n. stat. (from a subspecies of Orinanchonus lugens) and varicolor Voss, 1965, n. stat. (from a subspecies of Anchonidium sylvestre). One Aparopionella species-group name is a new junior synonym (Hoffmann's name having priority): ellipticus Hoffmann, 1965 (Merunymus) = lugens Voss, 1965 (Orinanchonus), n. syn. Ten new combinations are proposed: Aparopionella angulicollis (Voss, 1965) n. comb, (from Anchonidium), A. elliptica (Hoffmann, 1965) n. comb, (from Merunymus), A. esau (Voss, 1965) n. comb, (from Orinanchonus), A. hanangensis (Voss, 1965) n. comb, (from Orinanchonus), A. kenyae (Hoffmann, 1965) n. comb, (from Adichotrachelus), A. subcostata (Voss, 1965) n. comb, (from Orinanchonus), A. sylvestre (Voss, 1965) n. comb, (from Anchonidium), A. sylvicola (Voss, 1965) n. comb, (from Tosolophus), A. uniformis (Voss, 1974) n. comb, (from Anchonidium), and A. varicolor (Voss, 1965) n. comb, (from Anchonidium).
