Material. Type. Holotype ♀, Ukraine, Donetsk Region: Pokrovsk , 22.04.1963, 47°58'52.0" N 36°13'53.0" E. Paratype: 1 ♀, ibid., soil 5–10 cm, forest belt, 15.09.1969, specimen #S–114/129 (Skliar) ( SIZK) .

Non-type. Ukraine, Kyiv Region, Tetiyiv , industrial fruit garden, apple bark, 02.08.1990, slide #5399/62, 1 ♀, 49°25'36.0" N 29°40'35.0" E (Tulgren funnel) (coll. unknown) ( SIZK) .

R e d e s c r i p t i o n. F e m a l e. Dorsal shield ( fig. 8 , 1 ) moderately sclerotized, smooth, oval, with slight lateral emarginations; solenostomes 5 pairs (it, il, isc, is, ic; id not clearly expressed — in their place are dark rounded spots; iv missing). Dorsal setae PM3 and PM4 serrated, the rest smooth, differing in length. Seta AM1 longer then distance to theca AL1. Seta AL1 shorter then distance to theca AL3 which reaches the theca AL4. Seta PM 1 in 3.5 times shorter than PL1. Seta PL3 shorter than PL2 by 1.5 times and practically equal to PL3. Setae AL4 and PM3 of equal length. The peritreme reach the theca AD1. Ventrianal shield ( fig. 8 , 2 ) broadly pentagonal with slightly concave anterior margin and sculpture in the form of thin lines; anal pores contiguous, rounded. Metapodal shields elongated ( fig. 8 , 3 ). Posterior part of peritremal shield rounded, narrowing in middle part, then widening, and ending coracoid with terminal pore ( fig. 8 , 4 ). Оn Df seven teeth (5 distal, 2 basal); fifth tooth smoothed, and the seventh tooth at the finger base is miniature; Dm with 2 spaced teeth (the second tooth is smaller) ( fig. 8 , 5 ). Spermatheca with a small, insufficiently clearly differentiated sessile atrium and a narrow infundibulum widening towards the sacculus ( fig. 8 , 6 ). Leg IV with 3 long macrosetae: the shortest one on tibia ( fig. 8 , 7 ). Genu III with small macroseta. Genu II without macroseta.

Male unknown.

Diagnosis. From Amblyseius (Amblyseius) avetianae Arutujan et Ohandjanian , which is not represented in the fauna of Ukraine, Transeius proximus reliably differs by the AL1 half as long as the distance to the theca AL2; the distance between the anal pores much shorter than the distance between thecae in pair PrA2–PrA2; 6–7 teeth on Df and 1 on Dm; undifferentiated atritum fused with the base of the spermatheca funnel (whereas in A. avetianae the length of seta AL1 is equal to the distance to theca AL2; anal pores spaced on distance of thecae of setae PrA2–PrA2; 4 teeth on Df chelicerae and 2 on Dm; atrium elongated and delimited from the funnel) ( fig. 8, 8 , 10).

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. Ukraine: type locality and Kyiv Region, un- der maple bark, soil; rare .
