Abstract
The study of specimens collected during the night at a lamp allowed for the description of one new genus Phanreticula n. gen., and six new species, namely Phanreticula fenestrata n. sp., Habrocomes piotri n. sp., Conocephalus (Anisoptera) mollyae n. sp., Phlaurocentrum armatum n. sp., Tetraconcha danielae n. sp., and Tetraconcha fuscopunctata n. sp. Further, females of Paraeulioptera emitflesti Massa, 2020 (known only from the male sex) have been collected and characteristics of its ovipositor allowed for the inclusion of this species in the tribe Catoptropterigini. In addition, Pleothrix conradti (Bolívar, 1906) has been rediscovered after 118 years from its description from material collected in Cameroon, and the male of Griffinipteryx mukonja (Griffini, 1908), known only from three females collected in Cameroon in 1800s, is described for the first time. Finally, an updating of the species belonging to the genus Tetraconcha Karsch, 1890 has been carried out; presently, 24 species are known, including 2 other new species from the Ivory Coast (west tropical Africa), Tetraconcha alberti n. sp., and Tetraconcha tonkouiensis n. sp. Overall, 108 species of Tettigoniidae are listed here.
