Geographic distribution of Trachymyrmex jamaicensis (Hymenoptera: Formicidae)
Keywords:
biogeography, fungus-growing ant, geographic range, native rangeAbstract
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.
Resumen
Trachymyrmex jamaicensis (Andre) (Hymenoptera, Formicidae) es una hormiga raramente encontrada que cultiva hongos y es conocida solamente de las Indias Occidentales y del Sur de la Florida. He compilado y cartografiado >100 registros de sitios para T. jamaicensis, una documentación de los registros más antiguos conocidos para 15 áreas geográficas (países, estados de Estados Unidos, y las principales islas de las Indias Occidentales). Las poblaciones de T. jamaicensis tienen esencialmente un rango geográfico continuo desde la isla de San Vicente en el sur (13.1°N) a la Florida y las Bahamas en el norte (hasta 27.0°N). Casi todos los registros de la Florida provienen de los Cayos de Florida, al sur de 25.5°N; sólo hay 2 registros de T. jamaicensis de la parte continental de la Florida. En base a la escasez de registros de T. jamaicensis en la Florida, el Comité de la Florida de Plantas y Animales Raras en Peligro de Extinción (FCREPA) designó oficialmente T. jamaicensis como una especie rara.
