Abronia morenica, the Sierra Morena arboreal alligator lizard, is a species of lizard in the family Anguidae. It is endemic to the Sierra Madre de Chiapas in southern Mexico. It is known from cloud forests at elevations of above sea level, including both highly mesic ridgeline and more arid lower slope woodlands.
Abronia morenica possesses three distinct features that differentiate it from the other members of the subgenus Lissabronia to which it has tentatively been assigned. These are (1) lack of frontonasalâÂÂfrontal contact, (2) unexpanded supranasals, and (3) a lack of posterior subocularâÂÂprimary temporal contact. Adult males measure in snoutâÂÂvent length. The tail is about 1.6âÂÂ1.7 times the snoutâÂÂvent length.
