Oligodon deuvei is a species of snake in the family Colubridae. The species is endemic to Southeast Asia. The specific name, deuvei, is in honor of Jean Deuve (1918–2008) who was a French military officer and amateur naturalist.
O. deuvei is found in Cambodia, southern Vietnam, and Laos; it is expected to occur in northeastern Thailand. The preferred natural habitat of O. deuvei is forest, but it is also found in gardens. O. deuvei differs from other known species of its group (the O. taeniatus group) by the combination of 12–15 maxillary teeth, 17 dorsal scale rows at midbody, approximately seven supralabials, the absence of dorsal and tail blotches, and the presence of a single vertebral black stripe, which is usually orange or red. O. deuvei is most similar to O. barroni, but differs from the latter by having more maxillary teeth and its absence of dorsal and tail marks.
O. deuvei is terrestrial, semiaquatic, crepuscular and diurnal. O. deuvei preys predominately upon frogs and tadpoles. The mode of reproduction of O. deuvei is unknown. Wikipedia →

Possible
About 20% of wildlife watchers report a Deuve's Kukri Snake sighting in Cat Tien National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 28th most-seen of the 45 reptiles we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
June, September and December
In those months about 30% of wildlife watchers report a Deuve's Kukri Snake in Cat Tien National Park on a given day, against under 5% in February–March, May, July–August and October–November, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Deuve's Kukri Snake sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Only Cat Tien National Park, in our data
Cat Tien National Park is the only park on Wallace's Line with enough records to rate Deuve's Kukri Snake sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Deuve's Kukri Snake is recorded against all the reptiles logged in Cat Tien National Park (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.
