Two new species and new records of spiders (Aranei) in Dagestan (Russia)

Abstract

Two new spider species from the families Gnaphosidae and Zodariidae are described from the south of Russia (Republic of Dagestan). Haplodrassus nabozhenkoi Ponomarev, sp. n. is similar to H. signifer (C.L. Koch, 1839) and H. pseudosignifer Marusik, Hippa et Koponen, 1996, from which it differs in the shape of the embolic apophysis (slightly curved, almost straight in the new species), the structure of the embolus, the shape of the lateral pockets and the fovea of epigyne, the size of spermathecae (they are relatively larger in the new species). Zodariellum dagestanum Ponomarev, sp. n. is similar to Z. volgouralense Ponomarev, 2007, from which it differs in the smaller size and details in the structure of the male palp, and colouration. Data on the first records of Clubiona caucasica Mikhailov et Otto, 2017, Diaea livens Simon, 1876 in Dagestan and Titanoeca caucasica Dunin, 1985 in Russia and Georgia are also provided.
