Cephennium perispinctum group

Species of moderate size and relatively robust habitus; body length 1.1–1.4 mm. Body of dark-reddish to dark-brown colouration. Eyes usually composed of approximately ten, rarely fewer ommatidia. Elytra with relatively large and more or less strongly transverse tomentose impressions anteriorly; humeral carina weakly pronounced and rather short, approximately as long as the combined length of the basal 2–3 antennomeres.

: protibia subapically strongly curved or angled and distinctly excavate on inner side (exception: C. immutatum ); metaventrite flattened or shallowly impressed; aedeagus long and slender, 0.38–0.66 mm long; ventral process apically with more or less pronounced median extension ( Figs 25–35 ); internal sac with weakly sclerotized structures, without distinct spines; parameres gradually tapering apicad and with long apical seta.

Species of the C. perispinctum group are regionally or locally endemic in Northwest Turkey, South Turkey, Southeast Bulgaria, and the Caucasus region ( Georgia, Azerbaijan).
