Phrynosoma braconnieri, the short-tailed horned lizard, occurs only in pine-oak woodland and xeric thorn-scrub of Puebla and Oaxaca, Mexico. It may also inhabit Veracruz. P. braconnieri can be distinguished from other horned lizard species by the following: one row of lateral abdominal fringe scales; two moderately developed occipital spines, short, heavy and separated; temporal horns very reduced; very short tail; all ventral scales keeled; and nostrils in the line of the canthus rostralis.
