those of the descriptions given by Chant and Hunsell (1971), Congdon (2002) and Kolodochka and Gwiazdowicz (2016). However, the number of teeth on the movable digit in the material here observed is a variable character as some females had two teeth instead of three in the original description and further redescriptions. This species is common on grassy plants in dark spruce forests or in mixed forests with a predominance of spruce. It could be often found together with Amblyseius rademacheri Dosse (personal observation).
