Senticolis is a genus of nonvenomous snake in the family Colubridae. The genus Senticolis is monotypic, containing the sole species Senticolis triaspis, also known as the green rat snake. The species is endemic to Central America, Mexico, southern Arizona, and southern New Mexico.
Senticolis triaspis may grow to a total length (including tail) of 160 cm (63 in). Dorsally, it is green or olive green, and ventrally it is light yellow.[3] The head is elongated, the body is slender, and the smooth dorsal scales are arranged in 31-39 rows.[4]
Senticolis triaspis usually inhabits evergreen forests and grassland.[3]
Senticolis triaspis is well distributed in the Baboquivari, Pajarito, Atascosa, Santa Rita, Empire, Patagonia, Chiricahua, Swisshelm, Pedregosa, and Peloncillo mountains of southeastern Arizona.[3]
Senticolis triaspis consumes small animals such as lizards, birds, and bats, killing them by deadly constriction.[3]
Senticolis triaspis is primarily diurnal.[3]
During reproduction, an adult female of S. triaspis is able to lay up to 9 eggs in a clutch.[3]
Three subspecies are recognized as being valid, including the nominotypical subspecies.[2]
Nota bene: A trinomial authority in parentheses indicates that the subspecies was originally described in a genus other than Senticolis.
