Material. Type. Holotype}: Germany: “Karl Marx Stadt, near Rottis (Vogtland), Elsterhang, on fern, 26.09.1967, specimen #296”, (not located, not examined).

Non-type. Ukraine, Kharkiv Region, Chuguev, on grass, 06.10 1991, specimen #S–515 (ph-18), 1}, 1 {, specimen #S–516 (ph-19), 1 {(Khaustov).

R e d e s c r i p t i o n. F e m a l e. The dorsal shield ( fig. 2 View Fig , 1 View Fig ) is well sclerotised, oval in shape, with small lateral notches, smooth, with a dark marginal border; 7 pairs of solenostoms (it, iv, id, il, isc, is, ic). The setae of the PM4 are slightly serrated, the rest are smooth, varying in length from miniature to long. Seta AM1 approximately equal in length to the distance from its proper theca to theca of seta AL1. Peritreme long, reaches the base of the seta AD1. Ventrianal shield ( fig. 2, 2 View Fig ) rounded-pentagonal, in the anterior third with distinct lateral notches, the posterior part of the shield is wider than the anterior part, bears 3 pairs of preanal setae; anal pores are small, round, not close together. The walls of the spermatheca funnel are thickened, becoming thinner towards the sac; the atrium is large, sessile; the large duct is thickened ( fig. 2 View Fig , 3 View Fig ). There are 8 chelicerae on Df and 3 on Dm ( fig. 2 View Fig , 4 View Fig ). Metapodal scutes are asymmetrically elongated oval, the anterior one is smaller than the posterior one ( fig. 2 View Fig , 5 View Fig ). The curved posterior part of the peritremal shield is not beak-shaped but ending in a straight cut ( fig. 2 View Fig , 6 View Fig ). Leg IV with 3 macrochaetes: on the genu and basitarsus of equal length and longer than on the tibia ( fig. 2 View Fig , 7 View Fig ).

Measurements: Lds 345, Wds 200, Lvas 114, Wvas 95, Lian 41, Ltar IV 106; setae length: AD1 23; AD2 9; AD3 7; PD2 7; PD4 10; AM1 32; АМ2 6; AL1 14; AL3 27; AL4 46; PL1 11; PL2 9; PL3 11; PM1 8; РМ3 63; РМ4 155; AS 19; PS 14; PV 63, MCh: gen 54, tib 42, tar 55, gen III 25, tar II 22.

Male. There are 3 pairs of ventrianal setae, and small round anal pores ( fig. 2 View Fig , 8 View Fig ). The spermatodactyl L-shaped ( fig. 2 View Fig , 9 View Fig ). Lds — 305.

Diagnosis. Differs from the closely related A. wainsteini Gomelauri, 1968 b in almost three times shorter setae PL1 and 1.5 times longer PM4, more shorter setae AM1, AL4 and PL1, a wider ventroanal shield in the posterior half, the structure of the male spermatodactyl, the presence of 7 teeth on the Df of the female versus 9 teeth in A. wainsteini . Mite A. filixis differs from another related species, A. nemorivagus Athias-Henriot, 1961 , in having some shorter dorsal setae PM4, AL1, AL3, and PM3.
