Temascaltepec, México, Mexico.
May be sister to X. lachrymosus on basis of molecular data. Assessment of geographical variation complicated by marked individual variation in coloration, overall size, and pattern of streaking (width and shape) both above and below. Race mentalis poorly differentiated from nominate, and intergrades with latter in W Guerrero and with tardus in W Durango; saltuarius, ascensor and ultimus weakly differentiated from eburneirostris. Populations of yucatanensis at base of Yucatán Peninsula show signs of intergradation with eburneirostris, as perhaps does ultimus in NE Costa Rican lowlands. Proposed form striatigularis, known only by type specimen from S Tamaulipas (Mexico), sometimes treated as full species, but recently shown to represent aberrant individual of present species. Race mentalis has normally been attributed to Lawrence, but is instead “Baird in Lawrence”#R#R. Eight subspecies recognized.
