The present work is a revision of the Palaearctic burrower bug genus Exosehirus Wagner, 1963 (Heteroptera: Cydnidae: Sehirinae). New data on the morphology and distribution are given. Structures of the female internal ectodermal genitalia and the completely inflated aedeagi are described and illustrated for the first time. An extended differential diagnosis as a comparison of the genus with representatives of all Palaearctic genera of the tribe Sehirini is provided. Based on characters of the terminalia of both sexes, two new species are described: E. elamensis sp. nov. from Southwest Iran, and E. essedonius sp. nov. from Kazakhstan. ‘Exosehirus’ steini (Signoret, 1884) nom. dub. is excluded from the genus Exosehirus and treated as a species incertae sedis. Exosehirus marginatus (Signoret, 1881) is recorded for Azerbaijan for the first time.
