Gulf Coast horned lizard Gulf Coast horned lizard The Gulf Coast horned lizard ("Phrynosoma wigginsi" ) is a species of horned lizards native to Baja California, Mexico. "Phrynosoma wigginsi" was split from "Phrynosoma coronatum" in 2004 on morphological evidence. "P. wigginsi" has a tan rather than chocolate forehead, a fourth "subrictal" spine below the eye, and a longer head than "P. coronatum".

The geographic range of "P. wigginsi" is restricted to the region around Mulegé and Loreto on the Gulf Coast

This species is known only from three locations: the type locality ("Cabacera del Rio Baboso, cerca a Lita', Carchi Province, Ecuador"), one other locality close by
