Reptilia    Squamata (part)    Phrynosomatidae  

Chihuahuan Short-horned Lizard
Phrynosoma ornatissimum Girard, 1858

SSAR 9th Edition Comments:
 Montanucci (2015, Zootaxa 4015: 1–177) proposed, based on morphological data, that populations of short-horned lizards from the arid short-grass plains of central and southern New Mexico represent a separate species from P. hernandesi, and that hypothesis was corroborated by the results of Leaché et al. (2021, Frontiers in Ecology and Evolution 9: 678110) based on principal component and phylogenetic analyses of RADseq nDNA data.
