Revision of the Afrotropical flea beetle genus Serraphula Jacoby and description of Bechynella, a new genus from Western and Central Africa (Coleoptera: Chrysomelidae: Alticinae)

In this paper a revision of the Afrotropical flea beetle genus Serraphula Jacoby, 1897 is reported. Three species previously attributed to this genus are transferred to the new genus Bechynella gen. n. and the following new combinations are established: Bechynella bohumilae (Bechyne, 1955) comb. n.; Bechynella pallens (Bechyne, 1955) comb. n.; Bechynella sesengensis (Bechyne, 1959) comb. n. The genus Serraphula includes currently 19 species, 16 of which are new to science: Serraphula aenea Jacoby, 1897; S. elongata Jacoby, 1900; S. puncticollis Bryant, 1944; S. alticola sp. n.; S. audisiana sp. n.; S. bulirschi sp. n.; S. colonnellii sp. n.; S. debiasei sp. n.; S. drakensbergensis sp. n.; S. duplessisi sp. n.; S. grobbelaariae sp. n.; S. monticola sp. n.; S. mpumalangaensis sp. n.; S. natalensis sp. n.; S. oberprieleri sp. n.; S. osellai sp. n.; S. transvaalensis sp. n.; S. uysi sp. n.; S. wittmeri sp. n. Lectotypes for S. aenea, S. elongata and S. puncticollis are designated. A key to all the species is presented as well as line drawings of male and female genitalia, scanning electron micrographs of some diagnostic morphological characters, and autoecological and distributional data.
