Distribution.

Known from Yunnan (new record) and Borneo (Figure 14 C). This collection represents the northern-most record in the distribution of Gnamptogenys treta .

Taxonomic note.

The identification is based on the key provided by Lattke (2004). Our material fits the holotype very well, except for the shape of the ventral process of the petiole, which is more rectangular in the material from Yunnan, whereas in the material from Borneo it is more triangular. Since this is the only difference we were able to observe, we treat it as intraspecific variation.

Natural history.

Gnamptogenys treta has been collected from the leaf litter in rain forest, secondary forest and limestone forest and rubber plantation.
