Abstract
A highly differentiated group of Ethiopian species of the subfamilia Meligethinae (Coleoptera: Nitidulidae) is revised. The species are selected on the basis of common characters such as extreme development of secondary sexual dimorphism and a three-segmented antennal club in ♂♂. From the extensive material of more than 2000 specimens, nine species are identified. Five of these are new and described here. - The kinship-relations between the nine species are elucidated using the methods of cladistic systematics as formulated by Hennig (1966). Eight characters are arranged in transformation series and the direction of reading is determined for each of them. These characters are: length, and symmetry of antenna, mandibula, clypeus, aedoeagus, pygidium, mentum and apex of elytra. As a result six monophyletic genera are realized. The revised genus-group itself is regarded as the terminal end of one of the lineages in the genera of Meligethini, related to the genus Pria Stephens 1830. - Four new genera are described: Microporellus n. gen., Cornutopria n. gen., Microporodes n. gen., and Palmopria n. gen. A new name, due to preoccupation, is proposed: Lechanteuria (= Prianella Lechanteur 1955), and Microporum Waterhouse 1876 is re-described in its original concept.
