Bachia trinitatis, commonly known as the Trinidad bachia, Trinidad worm lizard, or Trinidad hex-scaled bachia, is a species of lizard in the family Gymnophthalmidae. It is found in Trinidad and Tobago and Venezuela. L. Fitzinger in 1826 described the species Brachypus cuvieri, which may refer to any four-toed Bachia species, and which has been suggested to be a senior synonym for Bachia trinitatis in the past. However, the holotype and type locality for cuvieri are now unknown, making it difficult to apply the name to a single species. Furthermore, a 1839 redescription of the species by André Duméril and Gabriel Bibron was based on three lectotypes belonging to three different species, leading to cuvieri generally being considered a nomen dubium or nomen nudum in the present.
Bachia trinitatis was formally described by the American herpetologist Thomas Barbour as Scolecosaurus trinitatis in 1914 on the basis of an adult specimen collected from Caparo, Trinidad. The Brazilian biologist Paulo Vanzolini moved it into the genus Bachia in 1961 and the R. Thomas further demoted it to a subspecies of Bachia alleni in 1965. Dixon in 1973 considered both alleni and trinitatis... Wikipedia →

No species of the same family or order lives in Main Ridge Forest Reserve, so these are its closest relatives here: other reptiles.
Possible
About 30% of wildlife watchers report a Trinidad worm lizard sighting in Main Ridge Forest Reserve on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 14th most-seen of the 24 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.
November and December
In those months about 50% of wildlife watchers report a Trinidad worm lizard in Main Ridge Forest Reserve on a given day, against under 5% in January–February, April and July–August, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Trinidad worm lizard sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Main Ridge Forest Reserve, in our data
Main Ridge Forest Reserve is the only park on Wallace's Line with enough records to rate Trinidad worm lizard sightings: about 30% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Trinidad worm lizard is recorded against all the reptiles logged in Main Ridge Forest Reserve (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.
