Scolecophis

Scolecophis is a monotypic genus in the family Colubridae, meaning the genus holds just one recognized species, the Black-banded Snake (Scolecophis atrocinctus). It belongs to the large and diverse colubrid assemblage, the same broad family that contains kingsnakes, racers, and many ground-dwelling New World snakes. Like most colubrids, it is a slender, non-constricting terrestrial snake rather than a member of the front-fanged venomous families such as vipers or elapids.

The genus is associated with the dry forests and lowland habitats of Central America, with records spanning parts of the region from Guatemala and Honduras south through Costa Rica. Members are small and ground-oriented, spending much of their time under leaf litter, rocks, and surface debris where they hunt and shelter. In general terms, the Black-banded Snake is recognized by a banded pattern of dark crossbands set against a paler ground color, a look shared by several small banded colubrids in the region, which is why field identification should rest on a careful look at the whole animal rather than color alone.

Scolecophis is a rear-fanged colubrid, with enlarged grooved teeth set toward the back of the upper jaw and a mild oral secretion used to subdue small prey. Snakes of this kind are not considered dangerous to people and there are no records of medically significant bites, but no wild snake should be handled, and a bite from any rear-fanged species can cause local irritation. If a person is bitten and develops anything beyond minor local effects, do not attempt home treatment; contact emergency services or, in the United States, Poison Control at 1-800-222-1222. As a small leaf-litter predator, it feeds on invertebrates and small prey it encounters on the ground, and like most colubrids in its range it is egg-laying, with detailed reproductive and behavioral records remaining limited for this obscure species.
