'''''Senticolis''''' is a [[genus]] of non[[venomous snake]] in the [[Family (biology)|family]] [[Colubridae]]. The genus ''Senticolis'' is [[Monotypic taxon|monotypic]], containing the sole [[species]] '''''Senticolis triaspis''''', also known as the '''green rat snake'''. The species is [[Endemism|endemic]] to [[Central America]], [[Mexico]], southern [[Arizona]], and southern [[New Mexico]].
'''''Senticolis triaspis''''', also known as green rat snake, is a long (160&nbsp;cm), green or olive green snake with the light yellow ventral side.

Habitat[edit]

Senticolis triaspis usually inhabits evergreen forests and grassland.[3]

Geographic range[edit]

Senticolis triaspis is well distributed in the Baboquivari, Pajarito, Atascosa, Santa Rita, Empire, Patagonia, Chiricahua, Swisshelm, Pedregosa, and Peloncillo mountains of southeastern Arizona.[3]

Diet[edit]

Senticolis triaspis consumes small animals such as lizards, birds, and bats, killing them by deadly constriction.[3]

Reproduction[edit]

An adult female of S. triaspis is able to lay up to nine eggs in a clutch.[3]

Subspecies[edit]

Three subspecies are recognized as being valid, including the nominotypical subspecies.[2]

  • Senticolis triaspis intermedia (Boettger, 1883) – Arizona, New Mexico, northern Mexico
  • Senticolis triaspis mutabilis (Cope, 1885) – Central America
  • Senticolis triaspis triaspis (Cope, 1866) – southern Mexico

Nota bene: A trinomial authority in parentheses indicates that the subspecies was originally described in a genus other than Senticolis.
