The English common names for Erythrolamprus melanotus refer to English biologist George Kearsley Shaw, who described and named this snake as a species new to science in 1802. Erythrolamprus melanotus belongs to the genus Erythrolamprus, which contains over 50 species. The genus Erythrolamprus belongs to the subfamily Dipsadinae, which is sometimes referred to as the family Dipsadidae. The relationships of Erythrolamprus species located in northern South America (Venezuela) can be shown in the cladogram below, based on molecular DNA analysis:
Erythrolamprus melanotus grows to a total length (tail included) of 43 cm (17 in). Dorsally, it has a light yellow or pinkish color, with a wide, dark vertebral stripe, which is bordered on each side by a thin whitish stripe, followed by a thin dark stripe.

Possible
About 30% of wildlife watchers report a Black-backed Snake sighting in Main Ridge Forest Reserve on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 11th most-seen of the 24 reptiles we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
April and June
In those months about 40% of wildlife watchers report a Black-backed Snake in Main Ridge Forest Reserve on a given day, against under 5% in January–March, August and November, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Black-backed Snake sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 parks where we can rate Black-backed Snake sightings, Main Ridge Forest Reserve has the highest daily chance: about 30%. Next come Tayrona National Natural Park (Colombia, about 20%).
GBIF citizen-science records
It is estimated from how often the Black-backed Snake is recorded against all the reptiles logged in Main Ridge Forest Reserve (11 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
