Non-type. 3 specimens (3 ♀). Ukraine: Autonomous Republic of Crimea, Main mountain Range, Nikitskaya yayla, 1400 m a. s. l., tract Krasnyi Kamen, Verbascum sp. , 15.06.1976, specimen #2053a , 1 ♀, 44°30'55.0" N 34°05'47.0" E; ibid., Knautia arvensis , 21.06. 1976, specimen #2154 , 1 ♀ (Kolodochka); Kharkiv Region, Zmievsk District, Mokhnach village , forest on the river bank, field mouse (combing mouse fur), 27.07 1979, specimen # P–513 (112) , 1 ♀, 49°42'25.0" N 36°21'24.0" E (Naglov) ( SIZK) .

Redescription. Female. Dorsal shield ( fig. 5 , 1 ) well sclerotized, with a dark marginal border on the sides, broadly oval, without lateral notches, smooth in the central part of the anterior half of the shield, obliquely striated along the lateral margins, covered with reticulate sculpture in the posterior half. There are 6 pairs of dorsal solenostomes (it, iv, isc, il, is, ic; missing id). Solenostomes ic and ic are the largest, the rest are noticeably smaller. The solenostome il displaced to the edge of the shield towards the seta PS. Dorsal setae thin, pointed, smooth (except for slightly serrate PM 3 and PM 4). Setae AM 4, PM 3, PM 4 nearly the same length and longest on dorsum, others short, more or less equal in size. Seta AM 1 does not reach the theca AL1. Seta AL3 located in common arc of setae AM 1–AL1–AL3–AL4. Setae of row PL almost equal in length (differences are 2–3 μ). Perithremes reach the techae of setae AD1. The shields of the ventral side of the body are well sclerotized. Ventrianal shield ( fig. 5 , 2 ) wide, wider than genital one, rounded pentagonal, narrowing caudally, entirely covered with reticulate sculpture; anal pores distinct, not close together. Metasternal shields elongate-oval, anterior scutellum smaller than posterior one ( fig. 5 , 3 ). Posterior part of peritremal shield slightly curved, pointed at end ( fig. 5 , 4 ). There are 3 teeth on Df and 1 on Dm ( fig. 5, 5 ). Spermatheca with bell-shaped funnel and peak; the massive sessile atrium is pressed into the funnel ( fig. 5 , 6 ). Leg IV has 3 macrochaetes: genu, tibia, and basitarsus, of which the latter is the longest ( fig. 6 , 7 ). There are no macrochaetes on the other legs.

Diagnosis. A. mauiensis differs from species of the genus Amblyseiulus known to the fauna of Ukraine in the reticulate sculpture of all idiosome shields; by six, not seven, pairs of dorsal solenostomes; by unusual displacement of the solenostome il to the edge of the shield. It is similar to A. sororculus (Wainstein, I960), which is often found in Ukraine, from which it is easily distinguished by wide genital and ventrianal shields, a visor on the funnel of the spermatheca, while in A. sororculus the dorsal shield is smooth, the ventral shields are of moderate width, the funnel of the spermatheca is without a visor.

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), Transcaucasia ( Azerbaijan), Far East of Russia (Primorsky Territory), ( USA (Hawaii). In Ukraine: Steppe zone, Crimea; herbs, on small rodents; rare.

Note. Description, morphometry, and illustrations are given for non-typу specimens from the Crimea after comparing them with illustrations of this species in the publications of various authors.
