Barbour's tropical racer (Mastigodryas bruesi) is a species of colubrid snake found in the Caribbean.


The specific name, bruesi, is in honor American entomologist Charles Thomas Brues, who was one of the collectors of the type specimen.[2]

Geographic range[edit]

It is native to Saint Vincent and the Grenadines, and Grenada.


It can reach a total length (body plus tail) of about 83 cm (33 in). It is blue-gray to brown, with lighter lateral stripes.

Behavior and diet[edit]

It is diurnal, hunting frogs and lizards.


It can be found in xeric habitats, on the ground, and in bushes, where it sleeps at night.

Locality records[edit]

It has been recorded in the southwest corner of Saint Vincent and is widespread all over the Grenadines islands. It is also found on the southern half of Grenada, which is the farthest south it is distributed. It has been introduced to Barbados, probably around thirty years ago, where it has been incorrectly identified as Liophis perfuscus.
