Fedrizzioidea

Ventral view of female Klinckowstroemia starri, from Rosario & Hunter (1988).

Belongs within: Trigynaspida.

The Fedrizzioidea are a group of tropical mites most commonly found in association with passalid beetles. They are divided between the Klinckowstroemiidae, with well developed latigynal and mesogynal shields and an ellipsoidal male genital aperture between coxae III, and the Fedrizziidae, in which the latigynal and mesogynal shields are reduced and hidden by the ventral plate and the male genital aperture is subcircular and between coxae II–III (Lindquist et al. 2009).

Characters (from Lindquist et al. 2009): Holodorsal shield bearing numerous minute setae. Mesogynal and latigynal shields well developed or reduced and withdrawn under ventral plate. Sternal setae 1 on tetartosternum, sternal shield with three pairs of setae. Sternogynum entire, hinged along posterior margin of sternal shield and covering anterior genital opening. Endopodal shields fused to ventral plate (fused ventral, peritrematic, exopodal, and marginal elements) or free; pedofossae often present. Ventrianal shield obtriangular, meeting or partially fused to ventral plate. Palptibia and tarsus distinct, unfused; chelicerae with short digits and dense, mop-like mass of filamentous and ribbonlike excrescences; corniculi broad, membranous.
