Cyanomyia viridifrons

Putla de Guerrero, Mexico

.

Sometimes placed in genus Agyrtria. Closely related to A. violiceps, with which formerly considered conspecific. Until mid-20th century, holotype of present species was believed to represent an aberrant individual of A. violiceps owing to sexual and age-related variation in coloration of crown in both species; in addition, described forms Cyanomyia guerrerensis, Uranomitra derneddei and U. atricapilla all refer to present species, but were earlier considered synonyms of A. violiceps; when finally recognized as a valid taxon, present species was considered a race of A. violiceps; recent morphological and biogeographical studies, however, including discovery of zone of sympatry in Guerrero but no known hybridization, confirm validity of present species. Until recently considered conspecific with A. wagneri (see below). Birds from C Oaxaca have been awarded race rowleyi, but probably represent intergradation with wagneri in zone of supposed secondary contact. Two subspecies recognized.
