Crotalus durissus maricelae, the Maricela rattlesnake, is a subspecies of venomous pit viper from Venezuela. [1] [2]
The Maricela rattlesnake is a slender snake, less than a meter in length. It is greenish- or dark-brown, and it displays 22-24 light romboid markings. Its underside is a cream at the head, turning to grey for the rest of the body. [3]
Known to inhabit the upper basin of the Nuestra Senora River, the Maricela rattle snake prefers arid areas at elevations of 1800 - 2400 m. [3]
The maricela rattlesnake's status as a valid taxon is debated, [4] but recent studies declare it a valid subspecies. [3] [5]
Lachesis is a genus of pit vipers in the family Viperidae. Member species are found in forested areas of the Neotropics. The generic name refers to one of the Three Fates, Lachesis, who determined the length of the thread of life. Four species are currently recognized as being valid.
Pituophis catenifer is a species of non-venomous colubrid snake endemic to North America. Nine subspecies are currently recognized, including the nominotypical subspecies, P. c. catenifer, described here. This snake is often mistaken for the prairie rattlesnake, but can be easily distinguished from a rattlesnake by the lack of a tail rattle, no black-and-white banding on its tail, and by the shape of its head, which is narrower than a rattlesnake's. Additionally, rattlesnakes possess a large venom gland located behind each eye, giving their heads a much rounder, more angular shape, as opposed to the more cylindrical, slender head shape of a gopher snake or other colubrid.
The timber rattlesnake, canebrake rattlesnake, or banded rattlesnake is a species of pit viper endemic to eastern North America. Like all other pit vipers, it is venomous, with a very toxic bite.

No subspecies are currently recognized.
Crotalus basiliscus, known as the Mexican west coast rattlesnake, Mexican green rattler, and also by other names, is a species of pit viper in the family Viperidae. The species is endemic to western Mexico. Like all other pit vipers, it is venomous. The specific name, basiliscus, is derived from the Greek word for king, βασιλισκος, and alludes to this snake's large size and potent venom. No subspecies are currently recognized.
