Size. 362 mm SVL, 120 mm tail; tail 33.1% SVL.
Identification. Rostral visible from above; eight upper labials; 9−10 lower labials; fourth and fifth upper labials enter the orbit; two primary and one secondary temporals; one preocular; two postoculars; a divided anal plate. Dorsal scales are in 17 rows at mid-body and reduced to 15 posteriorly; 143-146 ventrals; 66-77 subcaudals; upper labials are eight or nine, and there are eleven lower labials. The posterior ventral surface has some light mottling.
Distribution. This undescribed species is known from northeastern Tobago, and likely to be endemic. However, its eventual discovery in Venezuela cannot be ruled out. It is currently known from five specimens. Habitat. Primary and old-growth secondary forest. One specimen was found on a steep slope above a stream.
Biology. Diurnal. It is likely to be closely related to E. zweifeli and E. reginae from the Guiana Shield and have habits similar to those two species.
