Venter of female Oplitis aktius, from Lindquist et al. (2009).

Belongs within: Uropodoidea.

Oplitis is a genus of relatively small, weakly sclerotised uropodoid mites that are mostly found in association with ants. They are characterised by the presence of a forked pilus dentilis and usually a well-defined perigenital field (Evans & Till 1979).

Characters (from Evans & Till 1979): Weakly sculptured species typically with well-defined perigenital field; dorsal shield not divided; cheliceral shaft lacking sclerotised spoon-like process above dorsal seta, levator tendon of movable finger with sclerotised node; forked pilus dentilis present; pedofossae present; femur I with eight setae; genu I with pair of ventral setae.
