Global Range: Native to South America; part of a species complex that is widely distributed in lowland areas east of the Andes (Fuller et al. 1999). Humeralis was reported to be formerly established in Florida but now extirpated (Robins et al. 1991). However, the species actually was S. RHOMBEUS, not Humeralis (see Fuller et al. 1999). That locally established population was exterminated in 1977 (Fuller et al. 1999).
