Belongs within: Cheyletidae.

The Acaropsellini are a group of cheyletid mites found in association with plants or soil, or occasionally in bird or rodent nests (Bochkov & Fain 2001).

Characters (from Bochkov & Fain 2001): Gnathosoma well developed, about 30% or more length of idiosoma, without protrusions. Gnathosomal apex with or without short median protuberances. Palpal tarsus of female with one well-developed comb-like seta, one slightly barbed dorsal seta and two well-developed sickle-like ventral setae; male with one shortly barbed seta, one short nude seta and two sickle-like setae. Palpal claws slightly curved medially, with teeth, not thickened. All setae of palpal tibia hair-like. Palpal femur with 3 setae, palpal genu with 2 setae, not fused with femur, without protrusions, ventral seta of palpal genu situated at base of segment. Idiosoma ovoid. Eyes present. Shoulder-like projections of idiosoma absent. All idiosomal setae not exceeding half of idiosomal length. Neotrichial setae present or absent. Length of all legs not exceeding idiosomal length. Legs IV normally developed. Tarsi slender, with knobs not extending to pretarsus. Guard seta of tarsus I short, solenidion ω1 situated in basal half of tarsus I. Solenidions on tibia I-II present. Genu I with rod-like solenidion. Seta v1 of tarsus I situated at same level as solenidion ω1 and guard seta. Pretarsus and claws present on all legs. Apical seta of tarsus I normally long. Tarsal setae p' and p" hair-like. Coxae III with 2 setae. Trochanters I-IV with 1 seta. Distance between coxae II and III less than half of idiosomal width.
