Specimen Labels

The single specimen was collected in tropical moist forest. John Noyes collected the specimen using a screened sweep net.

Identification

A member of the Azteca aurita group. Azteca nanogyna has by far the smallest queen of any known species in the genus. The color and narrow head clearly ally it with Azteca lanuginosa and Azteca schimperi.

Biology

All known Azteca species are arboreal, nesting in living or dead wood, or external carton nests. Some species exhibit obligate associations with myrmecophytes, especially of the genus Cecropia (see Chapter 14 of The Ants). Feeding habits are generalized with foraging occurring both arboreally and on the ground.

Castes

Known only from the queen holotype specimen.
