Material. Type. Holotype ♀: Ukraine, Kyiv, Syretski Park , Juniperus sabina , 18.08.2008, specimen #5986/1622, 50°28'03.0" N 30°26'24.0" E (Omeri) ( SIZK).

Non– type. Ukraine: Lugansk Region, Stanytsa Luhanska, Luhansk Nature Reserve , manor of the reserve, Acer tataricum , 08.09.2013, specimen #6541, 1 ♀, 48°37'47.0" N 39°31'07.0" E (Kolodochka) ( SIZK) .

R e d e s c r i p t i o n. F e m a l e. Dorsal shield ( fig. 1, 1 ) weakly sclerotized, finely striated in anterolateral parts; dorsal solenostomes 7 pairs (it, iv, id, isc, il, is, ic). Dorsal setae point- ed, needle-shaped (both setae PL 1 broken off in holotype). Setae AD2–AD4, PD 2, PD 4, AM 2, PM 1 very short, AL4, PM 3, PM 4 elongate, others medium length. Setae PM 4 with 1–2 serrations, others smooth. Setae AM 1 and AL2 longer than the distance to the theca of the subsequent setae. Ventrianal shield ( fig. 1 , 2 ) small, oval, with 1 pair of preanal setae; anal pores small, distinct, round, located caudal to the level of theca PrA2. Setae V 1, V 2, PrA1, MV 1, MV 2, and PV on membrane surrounding ventrianal shield. Setae V 3 both absent. Perithremes extend beyond the level of the techae of setae AD1. Anterior metapodal shield linear, posterior curved ( fig. 1 , 3 ). The posterior part of the peritremal shield is slightly curved, rounded at the end with a short sharp process ( fig. 1 , 4 ). There are 3 large teeth on Df of the chelicerae, and 1 on Dm ( fig. 1 , 5 ). The funnel of the spermatheca is bell-shaped, the atrium is sessile ( fig. 1 , 6 ). Macroseta on legs pointed, smooth. Leg IV has 3 long macrosetae: longest on genu, shorter on basitarsus, and shortest on tibia ( fig. 1 , 7–9 ). Genu on other legs with short macrosete.

Diagnosis. Amblyseiella antonii is the only representative of the genus in the fauna of Ukraine. It can be easily distinguished from species of other genera outwardly similar to it by generic characters: the dorsal seta PL 3 and ventral seta V 3 are absent; the ventrianal shield is reduced, with only one pair of preanal setae.

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). In Ukraine A. antonii known only in two geographically distant localities in Wood-and-Steppe (Kyiv, shrub: Juniperus sabina ), and Steppe (Luhansk Region: trees: Acer tataricum ); rarely.
