The Mexican Plateau horned lizard[4] (Phrynosoma orbiculare) is a species of horned lizard in the family Phrynosomatidae.[2] The species, also known commonly as the Chihuahua Desert horned lizard,[5] is endemic to Mexico. There are five recognized subspecies. The specific epithet, orbiculare, comes from the Latin adjective orbis, meaning "circular".[4]
Description[edit]

P. orbiculare has a characteristic single row of lateral abdominal fringe scales. This "horned toad" also has two short occipital horns.[5]
Geographic range[edit]
P. orbiculare is found only in the high plateau country of central Mexico. Specifically, it is found in the Mexican states of Chihuahua, Durango, Morelos, Nuevo León, Puebla, and Veracruz.[5]
Habitat[edit]
P. orbiculare occurs in a wide range of primary habitats (dry scrubland, pine-oak forest, oak forest, juniper forest) and secondary habitats (agricultural land, and agave and Opuntia fields).[1]
Subspecies[edit]
Five subspecies of P. orbiculare are recognized as being valid, including the nominotypical subspecies.[2]
- Phrynosoma orbiculare bradti Horowitz, 1955
- Phrynosoma orbiculare cortezii (A.H.A. Duméril & Bocourt, 1870)
- Phrynosoma orbiculare dugesii (A.H.A. Duméril & Bocourt, 1870)
- Phrynosoma orbiculare orbiculare (Linnaeus, 1758)
- Phrynosoma orbiculare orientale Horowitz, 1955
Nota bene: A trinomial authority in parentheses indicates that the subspecies was originally described in a genus other than Phrynosoma.
Reproduction[edit]
P. orbicularis is viviparous.[2]
Etymology[edit]
The subspecific name, cortezii, is in honor of Spanish conquistador Hernán Cortés.[6]
The subspecific name, dugesii, is in honor of French-born Mexican naturalist Alfredo Dugès, who is considered the "father" of Mexican herpetology.[6]
