Identification
Hairs of mesosomal dorsum, gaster, femora, and tibiae conspicuously plumose, most trifid at about half the length, with side branches often as long as or longer than central branch (at very high magnification, traces of branching can be seen on the hairs of dentiloba, but side branches are extremely short); postpetiolar dorsum regularly longitudinally costulate; basidorsal costulae of AT4 at least half as long as length of postpetiole. This species looks nearly identical to dentiloba, but with plumose hairs.
Range
Costa Rica. Known only from La Selva Biological Station.
Natural History
Hylomyrma workers and queens occur in samples of sifted leaf litter from the forest floor. Little else is known about them.
Additional Records
This species is known from five isolated collections, all from Berlese or Winkler extraction of soil/litter samples.
