Diagnosis
Anemesia andreevae sp. nov. is largely similar in habitus to A. pallida sp. nov. and especially to A. sogdiana sp. nov., but differs from them by the long cylindrical palpal tibia and a shorter embolus in males (Figs 177, 197–198; cf. Figs 179, 182, 203–205, 211–212) as well as by the unique branched receptacles in females (Figs 233–234; cf. Figs 235–240, 250).
Etymology
The specific name is a matronym in honour of the late Central Asian and Polish arachnologist Dr Ekaterina Andreeva (Dr Katarzyna Andrejeva-Prószyńska; 1941–2008), who made a very significant contribution to the study of the spider fauna of Tajikistan; in the course of her numerous taxonomic
studies she described many regional spider taxa, including Brachythele karatauvi Andreeva, 1968 assigned later to Anemesia.

Variation
The length of the carapace varies from 4.30 to 5.53 in females and the number of maxillary cuspules ranges from 8 to 19. In females from Tajikistan (Varzob Canyon), the number of promarginal and retromarginal teeth may reach 8 and 6, respectively (see Fig. 80). The structure of the spermathecae appears to be almost the same in females collected from the different localities (Figs 233–234).
Habitat
The species occurs in the foothills covered with deciduous shrub with Prunus spp. and Pistacia vera L. (Fig. 310), and in the middle mountain belt. In the latter case the spiders were found inhabiting open forest biotopes dominated by Juniperus seravschanica Kom. and Acer spp. (Fig. 311).
Distribution
Southeastern Uzbekistan and western Tajikistan (Fig. 370).
