ABSTRACT. Two new species of the subfamily Erigoninae are described from the Caucasus: Asthenargus adygeicus sp.n. (Adygea Republic, Russia) and Maculoncus (?) obscurus sp.n. (Adygea Republic, Russia; Georgia). A. adygeicus sp.n. seems to be most similar to the Caucasian A. caucasicus Tanasevitch, 1987, but is distinguished by the absence of a mastidion in the male chelicerae, as well as by a few details of genitalic structure in both sexes. Since the taxonomic position of M. (?) obscurus sp.n., described from males alone, remains unclear, it is provisionally assigned to the genus Maculoncus Wunderlich, 1995.
