ABSTRACT. New faunistic records of 27 species of linyphiid spiders from the Adygea Republic and Krasnodar Krai, northern Caucasus, Russia are given. Diagnostic characters of Tenuiphantes perseus (van Helsdingen, 1977) and T. mengei (Kulczyński, 1887), two particularly similar congeners, are discussed. The fauna of the Caucasus comprises both T. mengei and T. perseus, as well as their presumable hybrids. The sole record of Walckenaeria incisa (O. Pickard-Cambridge, 1871) from the Caucasus is considered erroneous, actually concerning W. cuspidata Blackwall, 1833. Ceratinella wideri (Thorell, 1871), W. cuspidata and W. obtusa Blackwall, 1836 are new to the fauna of the Caucasus.
KEY WORDS: Araneae, faunistics, mountain fauna, taxonomy, hybridization.
