Speleognathinae
Speleognathinae is a of in the Ereynetidae comprising of the respiratory tracts of birds. These mites inhabit the nasal cavities and associated passages of avian across multiple continents. At least 37 in 15 have been documented from the Afrotropical region alone. The subfamily is distinguished from related nasal mite by morphological features used in taxonomic .
