Dorsum (left) and venter of Rhinonyssus coniventris echinipes, from Evans & Till (1979).

Belongs within: Gamasina.
Contains: Ptilonyssus.

The Rhinonyssidae are a group of endoparasitic mites found in the respiratory tracts of birds (Evans & Till 1979). At least some species use the claws of the first legs to tear the host’s nasal membrane, the chelicerae being only weakly membranous.

Characters (from Lindquist et al. 2009): Sternal shield reduced or absent but with distinct, and often distinctive, sternal setae, epigynal shield well developed or reduced, stigmata dorsal, peritremes greatly reduced or absent. Tibia and genu I each with two anterolateral setae.
