KEY WORDS: spiders, Alopecosa, redescriptions, spatial distribution, phenology, Crimea.

ABSTRACT. Redescriptions of two closely related species Alopecosa beckeri and A. taeniopus are provided based on specimens from Crimea. Comparative illustrations, diagnoses, spatial distribution, seasonal dynamic of activity for each species are presented. Distribution of A. beckeri presumably is limited by Crimean Mountains, and this species is endemic of Crimea probably. The earlier Crimean records of A. mariae and A striatipes are most possible misidentifications of A. taeniopus.
