Myobiidae

Myobia murismusculi, copyright Daktaridudu.

Belongs within: Cheyletoidea.

The Myobiidae are a group of mites ectoparasitic on mammals, adapted for clinging to the hair of their host.

Characters (from Walter et al. 2009): Soft-bodied, dorsoventrally flattened mites with legs I with or without claws, shortened and modified for grasping hairs, immatures with ventral unpaired clasping organ on
tarsus; legs II–IV with claws, but without empodia or tenent hairs; immatures with femora and genua fused on all legs; coxal seta 2a present; coxal fields vestigial. Prodorsum with four pairs of non-trichobothrial setae (vi, ve, si, se), idiosomatic shield and eyes absent. Chelicerae styliform, retractile within the gnathosomatic capsule, fused basally with each other and with the subcapitulum except at hypostomatic apex, remnant cheliceral seta (chb) or its alveolus present dorsally on capsule; palpi 2-segmented in adults, absent in immatures; gnathosoma of immatures proboscidiform. Female anal opening dorsal, separate from genital opening; male genito-anal opening dorsal, aedeagus typically elongate and generally directed forward. Dorsal lyrifissures (cupules) absent. With 5 active postembryonic instars: larva, protonymph, deutonymph, tritonymph, and adult.
