Natural History

One specimen from Panama was taken from litter berlesate, and another specimen from Chocó, Colombia was taken in mangrove and secondary forest, in a malaise trap. Longino collected a worker on a road through a pasture.


Colombian specimens have a slightly smaller HL, though with such few specimens at hand this could not be called a trend.
