Natural History:

I know this species from La Selva Biological Station and from Sirena in Corcovado National Park on the Osa Peninsula. At La Selva I know it from stray workers and males at blacklights. At Sirena I observed a colony or colony fragment. A tight column of 39 adults was moving along a trail. They stopped at one point, the column broke up, and individuals ran madly about in a small area. After about 10 minutes of this a less well defined column moved 1m away to a spot under a Cecropia leaf. They were carrying pupae and large larvae, and one worker was missing the gaster.


The type locality of punctaticeps is Jimenez, a site near present-day Guapiles, in the Atlantic lowlands of Costa Rica.

I used to call this species ambigua Santschi, and a different species (JTL-007) punctaticeps. John Lattke examined the types and concluded that ambigua was a junior synonym of punctaticeps, and the species I used to call punctaticeps was undescribed.
