ABSTRACT. Jaxartes golovatchi sp.n. is described and illustrated from the Ketmen Mountains, an outcrop of northern Tian Shan, SE Kazakhstan. The new species seems to be especially similar to J. stummeri Attems, 1904, but differs from congeners by the combination of the following characters: non-incised paraterga, an almost wanting metatergal sculpture, and the gonopod endomere that is clearly longer than a fringed distofemoral process.
KEY WORDS: taxonomy, Central Asia, Middle Asia.
