Abstract

After our recent revision of the Afrotropical species of Chevrolat, 1837, and the description of Kortenhaus & Wagner, 2011, five galerucine species that are closely related to and form a distinct monophyletic group, need to be transferred to a new genus, gen. n. Two of these species have already been described in the genus Chapuis, 1879, a junior synonym to . New combinations are (Laboissière, 1939), the genotype of the new genus, and (Laboissière, 1939) stat. n., originally described as a subspecies of the former . Three new species are described: sp. n., sp. n., and sp. n. Species of gen. n. are characterized by a broad body shape with a broad pronotum, convex dorsum, short antennae and legs, similar to those of . Males show characteristic sexual dimorphism in the shape and length of the metatibia. Genitalic structures, in particular the distinctive shape of median lobe, allow reliable species identification. Descriptions or redescriptions are given for each of the five species, including semi-schematic illustrations depicting the habitus outline, colouration, shape of the basal antennomeres and the median lobe. The material examined is listed in detail, and photographs of the name-bearing types, distribution maps and a key to the species are provided.
