Abstract
Two new species of two dysderoid families are described based on specimens collected from the Pamir Mountains in Tajikistan: the dysderid Dysdera bartang sp. n. (male) and the segestriid Segestria pamirica sp. n. (female). Both species were collected at elevations of 2200–2500 m a.s.l. (above sea level). Detailed descriptions, figures, diagnoses, habitat photographs and a distribution map are provided. The altitudinal limit of the species of Dysdera and Segestria in Central Asia is briefly discussed. Segestria pamirica sp. n. is likely to be the most high-altitude species of the genus in Central Asia and even in the world. An identification key to females of the Central Asian species of Segestria is also provided.
