Pituophis deppei, commonly known as the Mexican bullsnake and the Mexican pine snake, is a species of nonvenomous colubrid snake endemic to Mexico. There are two recognized subspecies.

Etymology[edit]

The specific name, deppei, is in honor of German artist Ferdinand Deppe, who collected natural history specimens in Mexico.[3]

The subspecific name, jani, is in honor of Italian herpetologist Giorgio Jan.[3]

Geographic range[edit]

P. deppei occurs in the Mexican states of Aguascalientes, Coahuila, Guanajuato, Hidalgo, Jalisco, Mexico, Morelos, Nayarit, Nuevo León, Oaxaca, Puebla, Querétaro, San Luis Potosí, Sinaloa, Sonora, and Tamaulipas.[2]

Habitat[edit]

The preferred natural habitats of P. deppei are forest, shrubland, and grassland, but it is also found in agricultural, suburban, and urban areas.[1]

Description[edit]

Dorsally, P. deppei is yellowish tan, with a series of large quadrangular blotches, which are dark brown to black. It has smaller dark spots on the sides. Ventrally, it is yellowish, with squarish brown spots. Adults may attain a total length of 1.69 m (5.5 ft), including a tail length of 18 cm (7.1 in).[4]

Reproduction[edit]

P. deppei is oviparous.[2]

Subspecies[edit]

Two subspecies are recognized as being valid, including the nominotypical subspecies.

  • Pituophis deppei deppei (A.M.C. Duméril, 1853) – southern Mexican pine snake
  • Pituophis deppei jani (Cope, 1861) – northern Mexican pine snake
