Geographic distribution of trachymyrmex jamaicensis (Hymenoptera: Formicidae)

Abstract

Trachymyrmex jamaicensis (André) (Hymenoptera, Formicidae) is a rarely encountered fungus-growing ant known only from the West Indies and South Florida. I compiled and mapped >100 site records for T. jamaicensis, documenting the earliest known records for 15 geographic areas (countries, U.S. states, and major West Indian islands). Populations of T. jamaicensis have an essentially continuous range from the island of St. Vincent in the south (13.1°N) to Florida and the Bahamas in the north (up to 27.0°N). Almost all records from Florida come from the Florida Keys, south of 25.5°N; there are only 2 records of T. jamaicensis from mainland Florida. Based on the scarcity of records of T. jamaicensis in Florida, the Florida Committee on Rare Endangered Plants and Animals (FCREPA) officially designated T. jamaicensis as rare species.
