Sonora annulata, also known commonly as the Colorado Desert shovelnose snake, is a species of snake in the subfamily Colubrinae of the family Colubridae.[1] The species is native to the southwestern United States and adjacent northwestern Mexico. There are two recognized subspecies.
Geographic range
In the United States, S. annulata is found in southwestern Arizona and southeastern California. In Mexico it is found in northeastern Baja California.[1]
Diet
S. annulata preys upon insects, scorpions, and lizards.[2]
Subspecies
Two subspecies are recognized as being valid, including the nominotypical subspecies.[1]
- Sonora annulata annulata (Baird, 1859)
- Sonora annulata klauberi Stickel, 1941 – Tucson shovel-nosed snake
Nota bene: A trinomial authority in parentheses indicates that the subspecies was originally described in a genus other than Sonora.
Etymology
The subspecific name, klauberi, is in honor of American herpetologist Laurence Monroe Klauber.[3]
