A new species, Cebrennus kazakhstanicus sp.  n., is described from south-eastern Kazakhstan based on female specimens. The new species is closely related to C. logunovi Jäger, 2000 from Turkmenistan and is representing the northeasternmost member of the genus: the type locality is in the Ili River delta, approximately 1100 km northeast from the closest known locality of the genus in Turkmenistan. Cebrennus kazakhstanicus sp. n. was collected at night, in sandy semi-desert. The new species differs from C. logunovi in the conformation of the epigyne. Comparative illustrations for female of C. logunovi are provided and the distribution records of the genus in Central Asia are mapped.
