Taxonomic history

Wheeler, G.
C & Wheeler, J. 1989a: 321 (l.).

Distribution:


Neotropical Region: Alajuela, Alta Verapaz, Aragua, Atlántida, Belize, Boaco, Cayo, Chiapas, Comayagua, Costa Rica, Ecuador, El Salvador, Gracias a Dios, Guanacaste, Guatemala, Heredia, Honduras, Izabal, Jinotega, Limón, Masaya, Matagalpa, Nicaragua, Panama, Petén, Puntarenas, Región Autónoma del Atlántico Norte, Región Autónoma del Atlántico Sur, San Salvador, Suchitepéquez, Venezuela

Distribution Notes:

Mexico, Guatemala (type locality), Costa Rica. Costa Rica: widespread in lowland wet forest, including the Osa Peninsula, Hitoy Cerere, La Selva Biological Station and surrounding Atlantic slope sites to 1000m, Penas Blancas Valley, and the Pitilla area of Guanacaste Conservation Area. Appears less common on Pacific side (one record from the Osa Peninsula, Ranch Quemado) than on the Atlantic side (many records).

Biology:

Natural History:

Workers and queens occur in samples of sifted leaf litter from the forest floor. Mike Kaspari collected a specimen at a barley bait in the La Selva successional plots.

Comments:

DNA barcode results show a division between specimens from southern Nicaragua vs. specimens from coastal Honduras to Chiapas, but I cannot find a morphological correlate.
