Ventral view of female Hypoaspis, copyright Pavel Klimov.

Belongs within: Laelapidae.

Hypoaspis is a genus of free-living predatory mites found in soil, litter and mosses. Females of most species bear a genital rather than an opisthogenital shield (Evans & Till 1979). Some species have been found under the elytra of beetles. Others are found living in arthropod burrows such as the Australian species H. barbarae which was found living on funnel-web spiders (Strong 1995). In members of the type subgenus, the anterior margin of the epistome is serrated whereas in the subgenus Hypoaspisella it is smooth.

Characters (from Evans & Till 1979): Apotele with two tines. Opisthonotum with Zx setae present. Chelicerae of male chelate-dentate, spermatodactyl free. Female typically with genital shield.
