Resumen

The Neotropical genus Phymatestes Pascoe, 1866 includes 23 species, of which five have been recorded so far in Peru. The monotypic genus Strongylacanthus Brèthes, 1925 currently placed in the Stenochiini tribe (Stenochiinae) is proposed as junior synonym of the genus Phymatestes (Coleoptera: Tenebrionidae: Lagriinae), based on the new synonymy of Strongylacanthus peruvianus Brèthes, 1925 under Phymatestes monstrosus Gebien, 1912. This nomenclatural change is based on morphological evidence obtained after examination of Strongylacanthus peruvianus type specimen and comparison with Phymatestes monstrosus specimens deposited in several entomological collections. Also, an updated checklist of the genus Phymatestes in Peruvian territory is presented, including the new record of Phymatestes brevicornis (Lacordaire, 1859). © GIRALDO 2025.
