Studies on chevron crickets: Tryposoma gen. nov. (Orthoptera, Anostostomatidae), a new genus from Tanzania

A new genus, Tryposoma gen. nov., is introduced to accommodate two African anostostomatid species formerly classified under the genus Libanasa Walker (Tryposoma kilomeni (Hemp & Johns) comb. nov. and Tryposoma brachyurum (Karny) comb. nov.). This taxonomic revision includes a key of the species. Detailed discussions on the genital structure of the newly described genus are also provided.
