R e d e s c r i p t i o n. F e m a l e. Dorsal shield ( fig. 8 View Fig , 1 View Fig ) well sclerotised, broadly oval, without lateral notches, smooth; 7 pairs of solenostomes (it, iv, id, isc, il, is, ic). Seta AD2 displaced laterally from the center line of the shield. Seta PM4 much longer than the other dorsal setae. The setae AD2–AD4, PD2, PD4, AM3, PM1, PL1, PL2, PL3 are miniature. Seta AM1 longer than distance to theca AL1. Peritremes long, reaching the level of theca AD1. The ventrianal shield ( fig. 8 View Fig , 2 View Fig ) is noticeably wider than the genital shield, near pentagonal with lateral notches, the anal pores are round, small, widely spaced. The metapodal scutes are widened, oval, the anterior one is smaller than the posterior one ( fig. 8 View Fig , 3 View Fig ). The posterior part of the peritremal shield is curved and ends rectangular ( fig. 8 View Fig , 4 View Fig ). Chelicera with 8 teeth on Df and with 3 on Dm ( fig. 8 View Fig , 5 View Fig ). The spermatheca is bell-shaped with thickened walls, the atrium is sessile ( fig. 8 View Fig , 6 View Fig ). Leg IV with 3 long macrochaetes: on the tarsus and genu they are almost equal, macrochaetа on tibia somewhat shorter ( fig. 8 View Fig , 7 View Fig ). Genu and tibia III and genu II with short macrochaetae.

M e a s u r e m e n t s: Lds 344, Wds 245; Lvas 110, Wvas 106, Lian 42; Ltar IV 110; setae length: AD1 28; AD2 5; AM2, PM2, PD1 — 5.5; PD4, PL2, PL3 — 8; AM1 36; AL1 22; AL2 39; AL3 58; PL1 11; PM3 83; PM4 115; AS 19; PS 14; PV 66; MCh IV: ge 56, ti 42, ta 58; MCh III: ge 30, ti 37; MCh II: ge 36.

Male. The ventrianal shield is triangular, with 4 pairs of preanal setae and anal pores not close together ( fig. 8, 8 View Fig ). The spermatodactyl is L-shaped, the lateral process at the end is bent to the side and expanded in the form of a scapula ( fig. 8 View Fig , 9 View Fig ), Lds — 320.

D i f f e r e n t i a l d i a g n o s i s. Only two known species of the genus Amblyseius , namely A. nemorivagus and A. filixis , with a dorsal seta AL1 twice as short as AL3. Moreover, they clearly differ in the proportions of the ventrianal shield, which in A. nemorivagus is widest in the anterior third, while in A. filixis , on the contrary, it is widest in the posterior third ( fig. 8 View Fig , 1 View Fig and fig. 2 View Fig , 1 View Fig ).

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, North Africa ( Algeria). In Ukraine: Wood-and-Steppe, montane Crimea (Main ridge: yayla, Karadag), grass, soil, forest litter, moss on stones, bark and dust of an old stump; rotting algae, small pebbles on the seashore; common in marine outfalls, rare in other habitats.
