A brief morphological characteristic of the genus Ubychia Rost, 1893 is given. Ubychia abagoensis Davidian et Arzanov, sp. n. is described from the Caucasian State Nature Biosphere Reserve in the Republic of Adygea, Russia. The new species is closely related to U. stygia Rost, 1893, from which it differs in the following features: penis is noticeably narrowed in the preаpical part and narrowly rounded at the apex, collum of the spermatheca is quite large and noticeably elongate. The new species differs from U. mingrelica (Reitter, 1894) in the following features: antennal funicle 5-segmented, pronotum and elytra with distinct fine punctation, apex of the penis rounded. The following new synonymy is established: U. stygia Rost, 1893 = U. solochaul Struyve, 2010, syn. n. Ubychia mingrelica is recorded from Russia for the first time based on a specimen from Sochi. A key to three species of the genus Ubychia known from the Western Caucasus in Russia is given.
