Material. Type. Holotype}, Georgia, Tusheti, Omalo, moss and lichen on the bark of a rotten birch, spiecemen #1112 (IZGT).
Non-type. 18} — Autonomous Republic of Crimea; Kharkiv Region.
R e d e s c r i p t i o n. F e m a l e. The dorsal shield (fig. 11, 1) is well sclerotised, with an expanded dark marginal border, smooth, oval with weakly defined lateral notches; There are 7 pairs of medium-sized solenostoms (it, iv, id, isc, il, is, ic). Setae AM1, AL4, PM2, PM3 are longer than the others (PM3 is the longest), AD1, AL1, AL3, PL1 are short, the rest are miniature. Seta AM1 reaches the theca of seta AL1. Long peritremes extending to the level of thecal setae AD1. The ventroanal shield (fig. 11, 2) is wider than the genital one, pentagonal with almost light or slightly concave lateral edges; anal pores round, spaced. The posterior metapodal shield is irregularly oval, one and a half times longer than the anterior one (fig. 11, 3). The peritremal scutellum is wide in the middle part, narrow and curved in the posterior part, and ends beak-shaped (fig. 11, 4). There are 17 chelicerae on Df (2 larger distal and 15 small ones), on Dm - 3 (fig. 11, 5). The funnel of the spermatheca is large, long, swollen at the atrium, then widens narrow to half the length of the funnel and widens towards the sac; the atrium is seated (fig. 11, 6). Legs IV have 3 macrochaetes; the longest on the genu, the shortest tarsus on (fig. 11, 7). Genu II, genu and tibia III with short macrochaetes.
Measuremants: Lds 415, Wds 295; Lvas 110, Vvas 106, Lian 42; Ltar IV 110; setae length: AD1 22; AD2 7; AD3 7; AD4 7; PD2 7; PD4 6; AM1 41; AM2 30; AL1 16; AL2 17; AL3 65; ML 8; PL1 11; PL2 9; PL3 9; PM3 95; PM4 130; AC 19; PS 14; PV 66; MS IV: 56, 42, 58 MS III: 30, 20; MCH II: 28 years old.
Male. Ventroanal shield covered with net sculpture; anal pores are small, round (fig. 11, 8). The spermatodactyl is L-shaped (fig. 11, 9). Lds — 370.
D i f f e r e n t i a l d i a g n o s i s. Similar to A. kalandadzei, differing in the shape and structure of the female spermatheca and the presence of a large number of small teeth on the Df chelicerae.
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 (Ukraine), Southern Caucasus. In Ukraine: Autonomous Republic of Crimea (Main and Inner mountain ranges, litter in oak-hornbeam forest, on tree bark), common; Kharkiv Region, on Apodemus flavicollis, rare.
