Geographic Variation

Three subspecies recognized:

nitidus, described as Vireo hypochryseus nitidus van Rossem 1934; type locality Hacienda de San Rafael, Chihuahua [= Sonora], Mexico.

Known only from southern Sonora.

Similar to nominate hypochryseus, but " brighter and more purely yellow below, and with the greenish wash on the flanks much reduced or lacking altogether" (van Rossem 1934: 465).

hypochryseus, described as Vireo hypochryseus Sclater 1862; type locality Mexico.

Occurs in western Mexico, from Sinaloa and western Durango south to Oaxaca. See Detailed Description.

sordidus, described as Vireo hypochryseus sordidus Nelson 1898; type locality Maria Madre Island, Mexico.

Occurs on the Tres Marias Islands, Mexico.

Differs from nominate hypochryseus in "duller, more olive green on dorsal surface, and dingier, more greenish yellow under parts. The bill is darker horn color and larger than in true [nominate] hypochryseus" (Nelson 1898: 10).

Related Species

There is no comprehensive phylogeny for Vireo. Investigations of relationships within Vireo on the basis of starch gel electrophoresis of protein coding loci (Johnson et al. 1988) and from phylogenetic analysis of mitochondrial DNA sequence data (Murray et al. 1994) did not include representatives of hypochryseus.
