Typical Antbirds (Thamnophilidae)
Dot-winged Antwren (Microrhopias quixensis) - HBW 8, p. 609
French: Grisin étoilé
German: Tropfenflügel-Ameisenfänger
Spanish: Hormiguerito del Quijos
Taxonomy: Thamnophilus quixensis Cornalia, 1849, eastern Ecuador.
Relationships uncertain; extensive study of morphological and vocal characters indicated close relationship with Formicivora; genetic study in which latter genus not included, however, suggested closeness to “stipple-throated antwren assemblage” of Myrmotherula. Races boucardi and virgatus intergrade in Honduras; future research may indicate that they should be merged. On basis of vocal as well as plumage differences, possibly also differences in habitat preferences, it is very likely that some other races merit elevation to species rank; e.g. emiliae su..

Ten subspecies recognized.
