New records, new combination and two new species in the genus Achaenops Suffrian, 1857 (Coleoptera: Cryptocephalinae)

Abstract

Two new species in the genus Achaenops Suffrian, 1857 are described and illustrated, A. lopatini sp. n. and A. nanus sp. n. from South Africa. A. lopatini sp. n. differs from all other species with impunctate pronotum and dark brown to black pronotum and elytra, by the confused puncturation of the elytra and the expanded pronotal side margins. A. nanus sp. n. is the smallest species in the genus, with sparse puncturation of pronotum, yellowish fore legs and dark brown mid- and hind legs. Coptocephala klassi Medvedev, 2006 is transferred to Achaenops: A. klassi (Medvedev, 2006) comb. n. New records are given for A. monstrosus Schöller, 2006, A. klassi and A. sericinus (Suffrian, 1857). The previously unknown male of A. sericinus is described. The genus is recorded for the first time from Free State, North West and Mpumalanga Provinces of South Africa. A check-list and a distribution map for the ten species in this genus endemic to South Africa are given
