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. Measurements.

M a l e unknown. 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.
