Natural History:

This species occurs in mature wet forest. It is a relatively common arboreal ant, nesting in dead branches and under epiphytes. Colonies often appear large, with workers scattered over a wide area.


Wilson (2003) examined the lectotype major of this species. For locality he put "Puerto Jimenez, Osa Peninsula," but this is probably an error. We are not certain if that town existed in the late 1800's, and it was not one of Alfaro's standard collecting localities. In contrast, Jimenez, near present day Guapiles on the Atlantic slope, was an Alfaro collecting site. It is the type locality for many Neotropical ants, probably including nitidicollis.

Based on Wilson's illustrations and text, we are not convinced there is a difference between Emery's nitidicollis and Wheeler's sagana.
