Abstract Two new species are described: Pygoplatys (s. str.) jordii n. sp. from Borneo, and P. (Odontoteuchus) berendi n. sp. from Sulawesi. The first key to the species of the genus Pygoplatys is given. A lectotype for P. bovillus Stål, 1871 is designated. Key words: Tessaratomidae,Tessaratominae, Pygoplatys, jordii n. sp., berendi n. sp., bovillus, key to species.
