Material examined — two females, Russia, Tyumen Province, vicinity of lake Kuchak , 57°21 ′ N, 66°03 ′ E, 27 April 2018, 11 August 2018, A. Khaustov coll., from humus GoogleMaps ; one female, Russia, Tyumen Province, forest park Zatyumensky , 57°09 ′ N, 65°27 ′ E, 19 April 2019, A. Khaustov coll., from moss GoogleMaps .

Supplementary description — Female Tarsus I with 37 setae, excluding apical sensorial setal cluster. Setae d3 18-19 with rounded tip, d4 33-35. Apical sensorial setal cluster (27B) includes 10 short setae of different shape. Setae df-1 (14), df-3 (8) and df-7 (8-9) finger-shaped with blunt tips. Setae df-2 (7), df-5 (6), df-6 (16-17) and df-8 (11-12) baculiform with rounded tips, setae df-8 usually curved. Setae df-4 (10), df-9 (9-10) spur-like with lobe-like tips, setae df-10 (5) situated between df-4 and df-9 also spur-like with acuminate tip.

Remarks — Amblyseius obtusus is a cosmopolitan species, reported in more than 30 countries ( Demite et al., 2020). All measurements and morphological characters of Siberian specimens are very close to redescription of Döker et al. (2020). It is a first record of A. obtusus in Asian Russia.
