Abstract. A description of Alopecosa tanakai sp.n. and redescription of A. kaplanovi Oliger, 1983, are given. Both species occur in the Maritime Province of Russia. These two species are of the same size and pattern, but their copulatory organs are very different. A brief discussion is provided for the complicated and contradictory synonymy of Alopecosa auripilosa (Schenkel, 1953), A. argenteopilosa (Schenkel, 1963), A. albofasciata fornicata (Schenkel, 1963) and A. aerosa (Schenkel, 1963) described from China.
