Supplementary description — Female Tarsus I with 37 setae, excluding apical sensorial setal cluster. Setae d3 15 with rounded tip, d4 30-32. Apical sensorial setal cluster (27A) includes 10 short setae of different shape. Setae df-1 (14), df-3 (9) and df-7 (7-8) finger-shaped with blunt tips. Setae df-2 (5-6), df-5 (8), df-6 (12) and df-8 (10-12) baculiform with rounded tips, setae df-8 usually curved. Setae df-4 (9), df-9 (9) spur-like with lobe-like tips, setae df-10 (6) situated between df-4 and df-9 also spur-like with acuminate tip.

Remarks — All measurements and morphological characters of Siberian specimens are very close to those of the redescription of Kolodochka and Gwiazdowicz (2016). This species is the most abundant in the investigated area. It is common on various grassy plants and often found with another species of Phytoseiidae mites in the present survey.
