Type species: Cimex littoralis Linnaeus, 1758 .
Description. Body black, oblong-oval or widely oval, medium-sized or large (4–8 mm), dorsally matte or with metallic luster, with blue reflection. Head moderately inclined. Eyes very large, ocelli widely spaced. Antennae long and fine, 2nd segment with long raised hairs. Calli of pronotum with median depression, large but low, reaching anteriorly lateral margin of pronotum. Posterolateral angles of pronotum rounded or weakly pointed, occasionally pale. Hemielytra long or shortened, covered with short raised, brown or golden, rarely long raised hairs. Embolar suture short. Secondary hypocostal ridge occasionally not reaching costal margin of hemielytron. Pale spots on corium absent, or small, or in form of longitudinal stripes. Membrane with 4 cells, innermost cell 3/4 as long as neighboring one; in individuals with shortened wings, membrane frequently coriaceous. 2nd segment of hind tarsus usually as long as, or longer than 3rd one. Filum gonopori of aedeagus forming 2.5–4.0 coils of spiral, middle sclerotized structure of aedeagus and larval organ absent.
The insects inhabit the sandy, clay silted shores of water bodies, wet meadows, and bogs; the species hibernates at the egg stage.
Distribution. Holarctic.
