The parthenogenic ant Platythyrea punctata is of general interest bio geographically because it occupies a very large range that extends from south Texas to Costa Rica and from Florida to most islands in the West Indies and the Bahamas. It is not known to occur in Panama, South America or Trinidad and Tobago. Throughout its range it is found in relatively undisturbed, wooded areas and is probably a native species (Deyrup et al., 1988; Deyrup, 2000). A seeming contradiction to this wide distribution is that it would seem to be a very poor disperser. Winged queens have only been found in Florida, the Bahamas and the Dominican Republic (Wheeler, 1905; K. Kellner, unpublished data). Moreover, queens presumably do not fly, because they lack ocelli, possess poorly developed thoraces and wing muscles (Schilder et al., 1999a) and do not appear to be collected in malaise traps (Deyrup & Trager, 1986). Colonies are presumed to reproduce mainly by splitting or fragmenting (fission or budding) and the ants subsequently disperse by walking over land.
