R e d e s c r i p t i o n. F e m a l e. Dorsal shield ( fig. 1, 1 ) well sclerotized, with wide dark stripe along posterolateral margins of shield, smooth, broadly oval with distinct lateral notches, narrowed frontally; dorsal solenostomes 7 pairs (it, iv, id, isc, il, is, ic). Dorsal setae smooth, varying in length. Setae PM3 and PM4 long (second noticeably twice longer), other setae varyingly shorter (up to microsetae). Setae AM1 and AL1 reach the theca next setae. Seta AL3 shorter than distance to base of seta AL4. Seta PL1 four times as long as each of PM1, PL2, and PL3 equal in length. Perithreme long, reaching base of seta AD1. Ventrianal shield wider than genital, elongated-pentagonal, widened at the level of anterior margin of anal valves, narrowed caudally, with lateral emarginations and sculpture in the form of thin transverse lines; anal pores round, spaced apart ( fig. 2, 2 ). The anterior metapodal shield is narrower and slightly smaller than the posterior one ( fig. 3, 3 ). Posterior part of peritremal shield slightly curved, beak-shaped ( fig. 4, 4 ). Chelicera with 8–9 teeth on Df and with 3 on Dm ( fig. 4 , 5 ). The funnel of the spermatheca is long, conical, widening towards the sacculus; its narrow part adjacent to the massive atrium is steeply curved ( fig. 4 , 6 ). Leg IV with 3 macrosetae: almost equal in length on basitarsus and genu, somewhat shorter on tibia ( fig. 4 , 7 ); on the genu and tibia III, and on the genu II short macrosete also present.

Measurements: Lds 390, Wds 225; Lvas 116, Wvas 97, Lian 54; Ltar IV 117; setae length: AD1 27; AD2 7; AD3 7; AD4 7; PD2 8; PD4 9; AM1 36; AM2 7; AL1 23; AL3 36; AL4 52; PL1 36; PL2 9; PL3 9; PM1 9; PM3 77; PM4 140; AS 27; PS 17; PV 72; MCh IV: ge 57, ti 38, ta 56; MCh III: ge 25; MCh II: ge 25.

Male. Ventrianal shield with three pairs of setae; anal pores round ( fig. 4 , 8 ). Spermatodactyl L-shaped ( fig. 4 , 9 ). Lds 300.

Diagnosis. According to the dorsal pattern of setae, T. begljarovi is similar to A. andersoni (Chant) and A. similis (Koch) , distinctly differing from them in stronger sclerotization of idiosomal shields, peculiar structure and shape of the cone-shaped spermatheca, and round, widely spaced anal pores, whereas in A. andersoni and A. similis , the spermatheca is cup-shaped, the anal pores are slit-like and shifted.

D i s t r i b u t i o n, h a b i t a t, o c c u r r e n c e. Europe, the Middle East, Azerbaijan. In Ukraine: Autonomous Republic of Crimea, shrubs, herbs; ordinary.

Note. Description, dimensions and illustrations are given for non-type specimens from the Crimea after comparing them with specimens from SIZK collection as well as on illustrations of this species in literary publications.
