Anystina is an infraorder of mites within the suborder Prostigmata (Trombidiformes). This group includes several of relatively active, often predatory mites. Members are characterized by features of the gnathosoma and leg chaetotaxy that distinguish them from other prostigmatan lineages. The infraorder encompasses such as Anystidae and related families, many of which occupy soil, leaf litter, and vegetation .
