A new species of Dysdera Latreille, 1804 (Aranei: Dysderidae) from South Ossetia, the Greater Caucasus

Abstract

A new species, Dysdera bakhanovi sp. n., is described from South Ossetia based on a male specimen. The new species is closely related to the Pontic-Caspian D. dunini Deeleman-Reinhold, 1988, the Anatolian D. anatoliae DeelemanReinhold, 1988 and D. krisis Komnenov et Chatzaki, 2016, and can be grouped within the anatoliae species-group. Males from the anatoliae species-group can be defined by the following characters: numerous small pits on carapace, non-sclerotized posterior apophysis, shortened psembolus bent anteriorly relative to the longitudinal axis of the bulb, and distal part of the psembolus bent at an angle of 90° from the posterior apophysis. Illustrations of the new species are provided. Distributional records of all species from the anatoliae species-group are mapped
