We describe Proterothrix paradoxornis n. sp. from Paradoxornis webbianus (type host) and Par. alphonsianus, P. longicaula n. sp. from Par. gularis, and P. sarahbushae n. sp. from Par. verreauxi (type host) and Par. alphonsianus. These are the first records of mites of the Pterodectinae from the Paradoxornithidae. Within Proterothrix, the new species constitutes a distinct complex, characterized by the presence of a long, whip-like aedeagus and spindle-shaped setae e on tarsi I in males. The diversity of feather mites (Acari: Astigmata: Analgoidea, In general morphological appearance, Proterothrix spp. repre- Pterolichoidea) on their avian hosts has been moderately well sent typical pterodectines, being characterized by a strongly surveyed for some non-passerine orders such as the parrots, elongated and narrow body, with a slightly convex and Psittaciformes (e.g., Dabert et al., 2008); however, many lineages extensively sclerotized dorsal side. As for most other pterodec- within the most species-rich order, the Passeriformes, remain tines, they occupy interbarb ‘‘corridors’’ on the ventral surface of almost unexplored. Among these are the parrotbills, an enigmatic vanes of the primary and secondary flight feathers of their host.
