Trachyuropoda

Trachyuropoda sp., copyright Centre for Biodiversity Genomics.

Belongs within: Uropodoidea.

Trachyuropoda is a genus of strongly sculptured uropodoid mites. Species are mostly myrmecophilous though the species T. termitophila is found in association with termites. Phoretic deutonymphs do not attach themselves to their host by means of an anal pedicel but instead grasp the host with strong claws (Lindquist et al. 2009).

Characters (from Evans & Till 1979): Strongly sculptured species without perigenital field; levator tendon of movable digit of chelicera with a sclerotised node; dorsal shield not divided; forked pilus dentilis present; idiosoma not constricted posterior to coxae IV; opisthogaster lacking sub-circular setae-bearing depressions; pedofossae present in both sexes; femur I with eight setae; genu I with pair of ventral setae; genua III and IV each with at least one ventral seta.
