Range
Pantropical tramp species known from tropical sites throughout the world; presumably dispersed by commerce (Bolton 1983, Brown 1949, Brown 1954). In Costa Rica, known from a citrus plantation near Muelle San Carlos, but could be expected in any lowland disturbed habitat.
Identification
Antennae 4-segmented; habitus as above. A detailed description is in Bolton (1983).
Natural History
This species has a distribution and habitat preference typical of tropical tramp species (Brown 1954). It occurs widely in many tropical and subtropical regions of the world, including oceanic islands such as Hawaii, and it is found most often in highly disturbed habitats such as beach margins and agricultural areas. The geographic origin of emmae is uncertain, but it appears most closely related to some African Strumigenys, and subsaharan Africa has been suggested as the original home (Bolton 1983, Brown 1954).
Type Data
Epitritus emmae Emery 1890:70. Holotype worker: Saint Thomas Island, West Indies [MCSN].
