Misidentified, not Brachythele birulai Spassky, 1937 . Diagnosis In habitus, Anemesia sogdiana sp. nov. is largely similar to A. pococki sp. nov. and especially to A. andreevae sp. nov. , but differs from them by the long, thin and gradually curved embolus in males ( Figs 203–205 , cf. Figs 193–194 , 197–198 ) as well as by the entire and narrowed subapically spermathecae in females ( Figs 235–240 , cf. Figs 228–229, 233–234 ). Etymology Sogdiana (‘ ΣΟΓΔΙΑνή ’, an ancient Greek derivate from the Old Persian Suguda ) is the name of an historical area in Central Asia that existed in the late antiquity and in the early Middle Ages ( IVth century BC – IXth century AD) and is applied to the territory located between the Amu-Darya and Syr-Darya Rivers which corresponds to the known range of this species. This specific epithet is a noun in apposition to the genus name, the gender is feminine.

Variation The length of the carapace varies from 4.87 to 5.21 in males and from 4.47 to 7.33 in females. Colouration varies through specimens very narrowly (see Fig. 30 ). Throughout the specimens, both PLE and PME may be reduced or even lost ( Fig. 69 ). In some females, the cheliceral furrow may be armed with 2–3 retromarginal teeth (see Fig. 82 ). In conspecific males, the shape of the palpal organ is almost identical ( Figs 203–205 ). Spermathecae show some variations and can feature with straight or bent stalks ( Figs 235–240 ). Habitat The known records mostly correspond to the midland mountain belt although the species can also occur in both the piedmont semi-desert (Zafarabad) and the highlands (Majanak); the preferred biotopes are represented by steppes and open forest communities with different species of Juniperus L., Crataegus Tourn. ex L. and Acer L. (see Figs 314–316 ). Distribution Central and southern Uzbekistan , and western Tajikistan ( Fig. 369 ). Note Charitonov (1969) listed five males of this species collected by K. Arnoldi and D. Fedotov in 1942 in the surroundings of Ishkent as Brachythele birulai Spassky. A detailed examination of the spider collection at the Perm University (1987, 1988) revealed the presence of only two appropriate male specimens sampled and labelled according to the mentioned record data.
