Trichouropoda orbicularis, photographed by Eric Palevsky.

Belongs within: Uropodoidea.

Trichouropoda is a genus of uropodoid mites characterised by the presence of one or two pairs of remarkably long posteroventral setae on the idiosoma (Evans & Till 1979). The species T. orbicularis may be found colonising food storages (Lindquist et al. 2009).

Characters (from Evans & Till 1979): Levator tendon of movable digit of chelicera with a sclerotized node; dorsal shield not divided; idiosoma with one or two pairs of outstandingly long setae posteroventrally; both sexes with pedofossae; genu I lacking paired ventral setae.
