Abstract: 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.
