Congruent co-evolution of the feather mite genus Trouessartia (Acariformes: Trouessartiidae) and endemic Malagasy warblers (Passeriformes: Bernieridae)

The feather mite genus Trouessartia (Analgoidea: Trouessartiidae), with 145 known species, is the second most species-rich genus of feather mites. Species of Trouessartia are mostly associated with passerines (oscines and suboscines), with a few associations with woodpeckers. On hosts, the mites inhabit flight feathers, most commonly occurring on the secondaries and rectrices.
