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 ngoylaensis sp. nov., and Pterotiltus campoensis sp. 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 Parapterotiltus gen. nov. with P. minimus as the type species and include in it Parapterotiltus minimoides sp. nov. and Parapterotiltus bamboutos sp. nov.

Genus Parapterotiltus gen. nov.
Type species.— Pterotiltus minimus Ramme, 1929.
Etymology.— Greek Para, near, close to; Pterotiltus, a genus of oxyine grasshopper, erected by Karsch, 1893.
Diagnosis.— Differs from Pterotiltus Karsch, 1893 only in the following particulars (Table 3): Size generally smaller; males average 12–14 mm in length, females 16–22 mm. Cuticle of fastigium and vertex in head and of thoracic and proximal abdominal tergites, coarsely punctate. Tegmina present but micropterous, barely exceeding the mesothoracic segment, rounded and sometimes brightly ...
