Abstract

The genus Pterotiltus Karsch, 1893 currently includes 12 described species from the equatorial forests of West and Central Africa. Here, we describe two new species from lowland forests of Southern Cameroon: Pterotiltus ngoylaensissp. nov., and Pterotiltus campoensissp. nov. We further describe two new species and the previously undescribed female of Pterotiltus minimus Ramme, 1929 from the highland areas of West Cameroon. These highland species share a suite of characters that distinguish them from Pterotiltus; these characters include structures of both the male and female reproductive systems, tegmina not completely regressed, and generally smaller size. To accommodate these differences between the species, we erect the new genus Parapterotiltusgen. nov. with P. minimus as the type species and include in it Parapterotiltus minimoidessp. nov. and Parapterotiltus bamboutossp. nov.
