The rare marsh beetle, Contacyphon quadrum (Klausnitzer, 1980) (Coleoptera: Scirtidae), is reliably recorded from Russia and the North Caucasus for the first time. The locus typicus for this species is problematic; according to various sources, Contacyphon quadrum was described from Armenia, Azerbaijan, or Russia (Dagestan). No new finds of the species are known. The study is based on the new material collected in Kabardino-Balkarian Republic using interception trap. The paper features pictures of aedeagi of Contacyphon quadrum and its related species from coarctatus-group. Also, the scirtid species Microcara luteicornis Reitter, 1888 recorded for Kabardino-Balkarian Republic for the first time.
