Anemesia infumata sp. nov. differs from A. incana by a considerably narrower clypeus and noticeably larger eyes in both males and females ( Figs 60 View Figs 48–62 , 74–75 View Figs 63–77 ; cf. Figs 59 View Figs 48–62 , 73 View Figs 63–77 ). From the most similarly-looking A. infuscata sp. nov., males of A. infumata sp. nov. differ in the more tapering embolus which arises closer to the retrolateral side of the palpal organ ( Figs 217–219 View Figs 215–223 ; cf. Figs 220–223 View Figs 215–223 ), while the conspecific females differ by their short and uniformly stout spermathecae ( Figs 255–257 View Figs 245–265 ; cf. Figs 258–265 View Figs 245–265 ).


The specific epithet is derived from the Latin adjective ‘ infumatusi ’, meaning ‘smoked’, referring to the mostly darkened (blackened) colouration of these spiders. The gender is feminine.

The length of the carapace varies from 6.65 to 6.78 in males and in females from 5.58 to 8.09. There are small variations in the eye size and arrangement as shown in Figs 74–75 View Figs 63–77 . The shape of the palpal organ in both collected male congeners looks practically the same. The configuration of the spermathecae does not show any noticeable difference ( Figs 255–257 View Figs 245–265 ).


As in A. incana (see above); however, A. infumata sp. nov. has been hitherto encountered in low and middle montane areas between 800 and 1700 m, with slopes covered by rarely standing trees ( Acer , Crataegus ), shrubs and steppe vegetation ( Figs 322–323 View Figs 322–329 ).


Known currently from a few localities in South Tajikistan only, see Fig. 273 View Figs 266–277 .


Two females from Akkutal Pass deposited in MIZW were collected, according to the cover label, by K. Andrejeva-Prószyńska, on the same date as the type series of Brachythele karatauvi : 23–25 Apr. 1967. It is likely, however, that these data are correct and that both groups of spiders were sampled during the same short-distance collecting trip. The measured air distance between Akkutal and Vahsh Karatau Mts is only 60–90 km, depending on the localities.
