Distribution Notes:

Mexico to northern Argentina and Bolivia. Costa Rica: Atlantic slope to 300m, Monteverde at 1400m.

Biology:

In Costa Rica, I know workers of this species from several widespread and diverse situations. Dana Meyer collected workers from a rotten log at Sirena in Corcovado National Park. I collected workers from a column on the main road in the Monteverde Cloud Forest Reserve, at 1500m elevation. I observed the column at 1240hrs. The column was tight, with rows of stationary workers on the sides, mandibles open and pointed upward. The column was partially on open ground, partially under a soil-covered gallery before disappearing underground. There were several phorid flies running with the column.

In Costa Rica, at La Selva and the 300m site on the Barva transect, most males have been collected at lights. Males have been collected in 15 different light trap samples. In an 18-month light trapping program, all males occurred from February to May, which is the dry season. One male was captured in a Malaise trap; given the intensity of Malaise trap sampling at La Selva, this is a very rare event. In Monteverde a male was found inside a house at night, apparently attracted to the light.

Identification:

Worker: Posterior face of propodeum straight, not concave, as long or longer than dorsal face; eye without distinct convex cornea; apex of scape does not exceed eye level; anteroventral tooth of petiole broadly triangular, shallow to nearly absent; face with abundant strong puncta; mesosomal dorsum with roughened sculpture; pilosity of mesosomal dorsum relatively dense, short, and of uniform length (contrasting with swainsonii, which has longer, sparser pilosity of variable length).

Comments:

Two males of N. halidaii, one from Nicaragua and one from Honduras, and three worker collections of N. punctaticeps from two sites in Honduras were submitted to BOLD for DNA barcoding. The results strongly support the conspecificity of these two forms. Neivamyrmex halidaii is the older name and should be made senior synonym.

Neivamyrmex punctaticeps was previously known as N. spinolae (Westwood 1842) (N. spinolai in Borgmeier 1955). Bolton (1995) showed that this was a junior homonym and used the oldest junior synonym as the replacement name.
