|Distribution||Mexico (Yucatan, Quintana Roo, Campeche), N Belize, Guatemala|
Type locality: Dzitas, Yucatan.
|Types||Holotype: UMMZ 73082|
|Diagnosis||Diagnosis: “Loreal present; a single elongate nasal; 6 upper labials; anal plate|
divided; 123 subcaudals.” (Gaige 1936: 300).
Habitat: Symphimus mayae appears to be both terrestrial and arboreal. In northern Yucatán the species is an inhabitant of xerophytic thorn forest and, along the eastern side of the peninsula, more mesic habitats, while in Belize it
occurs in oak hammocks within dry lowland savannas and probably semi-evergreen seasonal forest.
Sexual dimorphism is evident although males and females attain similar adult body sizes.
Diet: Symphimus mayae feeds almost exclusively on orthopteroid insects, principally katydids (Tettigoniidae) and crickets (Gryllidae). These taxa jointly
accounted for >50% of the total number of prey items recovered from stomachs and had been eaten by >70% of the snakes examined, with little intraspecific or seasonal variation.
