Trinidad and Tobago

Trinidad is a continental island of about 4800 km2 off the northern coast of South America. Together with Tobago (about 300 km2) and some associated very small islands, it forms the national territory of Trinidad & Tobago. Biotically, the two islands are set apart from the oceanic Lesser and Greater Antilles to the north, having a greater affinity to northern South America. The climate and seasonality of Trinidad & Tobago are typical of the humid tropics north of the Equator. Topography is slight, with no hill reaching 1000 m, and the predominant native vegetation is rain forest

The following valid species and subspecies of ants are known to occur in Trinidad & Tobago. Unidentified and undescribed species will be added to this list as identifications are verified and taxonomic revisions are published. This species list is based upon the effort of many ant collectors as well as myrmecologists who have published on the taxonomy of Trinidad & Tobago ants. Those who have specimen records that expand this list are encouraged to submit this information in the discussion section of the Trinidad & Tobago Ants web page.
