Revision of Aresceutica (Orthoptera: Acrididae: Catantopinae) with comments on related genera

Abstract

The East African forest genus Aresceutica Karsch is revised; there are now four valid species, including A. nguruensis, sp. n. from south eastern Tanzania. Aresceutica is extremely similar to the West African genus Serpusia; it differs only in the form of the prosternal tubercle and the detail of the phallic morphology. Two new combinations are proposed: Ptemoblax lemarineli Bolívar, 1911 = Aresceutica lemarineli (Bolívar, 1911), comb. n. and Aresceutica vansomereni Kevan, 1956 = Duviardia vansomereni (Kevan, 1956), comb. n.
