Specimens examined. Five females, RUSSIA, Tyumen Province, vicinity of lake Kuchak, 57°21’N, 66°03’E, 27 April and 06 September 2018 O. Joharchi coll., on Bombus   sp. ( Hymenoptera   : Apidae   ).

Notes. Pneumolaelaps hyatti   was described from Great Britain ( Evans & Till, 1966) where it was found on Bombus muscorum   L. ( Hymenoptera   : Apidae   ) and Davydova & Nikolsky (1986) reported this species from Western Siberia on the basis of specimens collected on bumblebees. We have not had the opportunity to examine any specimens to confirm this identification. This species is widely distributed in Asia, Europe and Russia in association with bumblebees or their nests ( Costa, 1966; Bregetova, 1977; Karg, 1993; Lapina, 1976; Ye & Ma, 1991). We take the opportunity to supplement the description given by Evans & Till (1966), on the basis of the new specimens. Our specimens agree well with the both description given by Evans & Till (1966, Fig. 33 View FIGURES 26–34 ) and Costa, 1966. The species is easily recognised by small cells of reticulation of dorsal shield, mostly as long as wide, dorsal shield setae j2, j3, z2–z4, s1–s4 and r2–r5 as long as j1, setae of opisthonotal area decreasing in length from anterior to posterior ( Fig. 56 View FIGURES 56–61 ), pre-sternal and sternal shields well separated, posterior margin of sternal shield strongly concave ( Fig. 57 View FIGURES 56–61 ), poststigmatal plate prominent, elongated triangular ( Fig. 58 View FIGURES 56–61 ), genital shield elongate, rounded posteriorly, surface with irregular diagonal lines and polygonal cells and expanded well just posterior to genital setae (st5) ( Fig. 57 View FIGURES 56–61 ), anal shield nearly as long as wide, hypostomal groove with six rows, each row with 3–6 denticles ( Fig. 59 View FIGURES 56–61 ). Some dorsal setae on femur and tibia legs I & II thickened (see Fig. 61 View FIGURES 56–61 ).
