Taxonomic note.

The identification is based on the key provided by Lattke (2004). The material from Yunnan shows some minor variation in the development of gastral sculpture, which we consider as geographic, intraspecific variation.

Natural history.

Gnamptogenys costata has been collected from foraging columns on the ground in rain forest and limestone forest.
