Oreocryptophis porphyraceus is a rat snake species, commonly called the black-banded trinket snake, red bamboo snake, found in mid to upper-level elevations of forested hills in southeastern Asia, ranging from evergreen tropical to dry seasonal forests depending on the subspecies and locality. It is the only member of the genus Oreocryptophis, but it was formerly placed in Elaphe.
The head is small, sharp and squarish, while the color pattern includes red or orange colors, along with black bands or stripes. A terrestrial species, it has a preference for cool climates that restricts its habitat to hills and mountain plateaus. It is known to be crepuscular, active during the late evenings till night and dawn till late mornings. In captivity, it is one of the most sought-after rat snake species.

GBIF citizen-science records
It is estimated from how often the Black-banded Trinket Snake is recorded against all the reptiles logged in Doi Inthanon National Park (6 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.
