Oaxacan Dwarf Boa

The Oaxacan Dwarf Boa is a small, secretive snake endemic to the cloud forests of the Sierra Norte de Oaxaca in southern Mexico. It is the sole species in its genus and is one of the rarer boas known to science, documented from a limited number of localities.

This species is harmless to humans and is of particular interest to herpetologists due to its restricted range and status as a Mexican endemic within a small monotypic genus.

• Small, moderately stout body with smooth scales
• Dark brown to blackish dorsal coloration, sometimes with faint mottling
• Relatively small head not strongly distinct from the neck
• Small eyes with vertical pupils typical of nocturnal, terrestrial boas
• Adults typically 30-60 cm in length

Restricted to humid montane cloud forest in the Sierra Norte de Oaxaca, Mexico, at moderate to high elevations. It is found beneath logs, rocks, and leaf litter in cool, moist forest environments.

Little is documented about its ecology due to its rarity, but it is believed to be a nocturnal, ground-dwelling predator of small vertebrates such as lizards and amphibians. Like other dwarf boas, it is presumed to be live-bearing, though detailed reproductive data remains limited.
