Oreocryptophis porphyraceus is a rat snake species, commonly called the black-banded trinket snake, red bamboo snake,^[2] 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,^[3] but it was formerly placed in Elaphe.^[2]

Description

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.

Distribution

India (Darjeeling, Sikkim, Assam, Arunachal Pradesh (Miao, Namdapha - Changlang district, Itanagar - Papum Pare district), Myanmar, Bhutan, Thailand, Laos, Cambodia, Vietnam, Nepal, South China (Tibet, Sichuan, Yunnan, Hong Kong, Hainan, northward to Henan and Gansu; south to Wei He river), Taiwan, West Malaysia (Cameron Highlands, Pahang), Indonesia (Sumatra). The type locality given is "India: Assam, Mishmi [Mishmee] Hills." It is also reported from Lowachhara National Park of North-eastern Bangladesh^[4]

Habitat

These rat snakes thrive under cool and very humid conditions. On many occasions they are found at altitudes exceeding 800 meters in evergreen moist rainforest or monsoon forests, depending on the subspecies and locality. They spend most of the time hiding in leaf litter, under moss carpets, or under rocks and logs.

Diet

The diet consists primarily of rodents and other small mammals in the wild. Frogs are a possibility. In captivity, mice are accepted readily.
