Hebius khasiensis, commonly known as the Khasi Hills keelback or Khasi keelback, is a species of colubrid snake endemic to southeastern Asia. It is found in parts of southern China (Tibet, Yunnan), eastern India (Assam), Thailand, Laos, Myanmar, Cambodia, and Vietnam.
It is a reddish-brown snake with a white transverse bar running across the supralabial scales. The dorsal scales are in 19 rows, rather strongly keeled, except for the smooth outer row. The ventrals number 150–154, the subcaudals 80–100. The anal plate is divided.
Adults are about 60 cm (23½ in.) total length, of which about 19 cm (7½ in.) is tail. The Khasi Hills keelback's nutritional intake consists primarily of toads. Boulenger, G.A. 1890.

With luck
About 10% of wildlife watchers report a Khasi Hills Keelback sighting in Doi Inthanon National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 22nd most-seen of the 30 reptiles we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
September and December
In those months about 30% of wildlife watchers report a Khasi Hills Keelback in Doi Inthanon National Park on a given day, against under 5% in January–August and November, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Khasi Hills Keelback sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Doi Inthanon National Park, in our data
Doi Inthanon National Park is the only park on Wallace's Line with enough records to rate Khasi Hills Keelback sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Khasi Hills Keelback 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.
