| Abstract: | The phylogeny of the Elateridae subfamily Thylacosterninae was studied using morphological characters and mitochondrial 16S rDNA sequences. Five monophyletic groups were recovered: the Asian Cussolenis , the American Pterotarsus , Balgus and Thylacosternus , and the African " Cussolenis ", which is described here as Lumumbaia new genus Muona & Vahtera (type-species Cussolenis attenuatus Fleutiaux, 1925). The following new combinations are made: Lumumbaia africanus (Fleutiaux, 1897) Soleniscus ], Lumumbaia praeustus (Fleutiaux, 1926) Cussolenis ], Lumumbaia nigripes (Fleutiaux, 1926) Cussolenis ], Lumumbaia robustus (Fleutiaux, 1925) Cussolenis ], Lumumbaia attenuatus (Fleutiaux, 1925) Cussolenis ] and Lumumbaia notabilis (Fleutiaux, 1926) Cussolenis ]. A key to the genera of the subfamily is provided. The data were efficient in recovering generic limits within the group. At species level the mitochondrial 16S rDNA data seemed to work unpredictably, either agreeing or not with traditional species-level limits based on male genitalia and body structure. The evolution of bioluminescence is optimized as a feature originating in the ancestors of clicking elateroids. © The Willi Hennig Society 2009. |
