The parasitic feather mites of the genus Fainalges are adapted to spend their whole life in the plumage of their host species, in this case several Central and South American parrot species.

So, for example, the Central American Green Conure (Aratinga holochlora (Sclater)) hosts at least seven species of this genus, Fainalges bilobatus (Pérez), Fainalges latistriatus (Pérez), Fainalges longissimus (Mejía-González & Pérez), Fainalges spiculatus (Pérez), Fainalges stettenheimi (Pérez), Fainalges tanythrix (Pérez) as well as Fainalges vulgaris (Pérez).


This feather mite species was discovered, together with five additional species, during the study of museum specimens of the Carolina Paraceet (Conuropsis carolinensis (L.)), and was scientifically described in the year 2005.

The Carolina Paraceet was extirpated at about 1918, followed by these highly specialised  parasites.
