Alfaria minuta

A nest was uncovered in a cocoa plantation close to the northcentral Venezuelan coastal town of Ocumare by Dr. Robert Johnson during the 2008 edition of Ant Course. The nest was found under a grapefruit-sized stone with a cusp shaped structure, it consisted of a single chamber dug out from the soil from which 24 workers were collected. Two specimens are deposited in the Museo del Instituto de Zoología Agrícola of the Universidad Central de Venezuela in Maracay, Venezuela, and the rest are in the Arizona State University collection. This observation further reinforces the notion that G. minuta group species are subterranean nesters, in contrast with most members of the genus which prefer to nest in decomposing wood.
