On the genera Scolochirus Marshall and Pseudoscolochirus Hoffmann, with the description of two new species (Coleoptera, Curculionidae, Entiminae, Cneorhinini)

Abstract

Type material of the described species of Scolochirus Marshall, 1944, and Pseudoscolochirus Hoffmann, 1963, was examined, and is completed with all available material of both genera deposited in museums. Lectotypes of Proictes biovatus Hustache, 1936 [current name Scolochirus biovatus (Hustache, 1936)], Proictes dentipes Hustache, 1920 [current name Scolochirus dentipes (Hustache, 1920)], Scolochirus armipes Marshall, 1944, and Scolochirus horridus Marshall, 1951, are designated. Scolochirus camerunensis n. sp. from Cameroon, and Pseudoscolochirus longirostris n. sp. from Ghana, are described and compared with all other species of the genera. Scolochirus cognatus Marshall, 1951, is proposed as junior synonym of Scolochirus dentipes (Hustache, 1920). Scolochirus armipes Marshall, 1944, is recorded from Central African Republic, Congo and Democratic Republic of the Congo for the first time, as well as S. biovatus (Hustache, 1936) from Democratic Republic of the Congo, Ghana, Nigeria and Togo, and S. dentipes (Hustache, 1920) from Liberia. Male and female genitalia of the both genera are described and illustrated for the first time. Keys to species of both genera are presented.
