Uromacer frenatus, the slender Hispaniolan vine snake or island pointed snake, is a species of snake in the family Colubridae. The species is endemic to Hispaniola in the West Indies. U. frenatus is found in Haiti and the Dominican Republic.
The preferred natural habitat of U. frenatus is forest at altitudes from sea level to 929 m (3,048 ft). U. frenatus is oviparous. Four subspecies are recognized as being valid, including the nominotypical subspecies. Uromacer frenatus chlorauges Schwartz, 1976
Uromacer frenatus dorsalis Dunn, 1920 Uromacer frenatus frenatus (Günther, 1865) Uromacer frenatus wetmorei Cochran, 1931 Nota bene: A trinomial authority in parentheses indicates that the subspecies was originally described in a genus other than Uromacer.
The subspecific name, wetmorei, is in honor of American ornithologist Alexander Wetmore. Boulenger GA (1894). Catalogue of the Snakes in the British Museum (Natural History).

Possible
About 30% of wildlife watchers report an Island Pointed Snake sighting in Jaragua National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 7th most-seen of the 9 reptiles we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
August
In that month about 60% of wildlife watchers report an Island Pointed Snake in Jaragua National Park on a given day, against under 5% in April, June and October–November, the lowest months. That is one of Jaragua National Park's wettest months, with about 100 mm of rain against 20 mm in January.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Island Pointed Snake sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Jaragua National Park, in our data
Jaragua National Park is the only park on Wallace's Line with enough records to rate Island Pointed Snake sightings: about 30% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Island Pointed Snake is recorded against all the reptiles logged in Jaragua National Park (12 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.
