Biology:

Recent collections of this species are from lowland wet to moist forest habitat, from 70–270 m elevation. The type is apparently from a somewhat higher site near Ocosingo. All recent specimens are from Winkler samples of sifted leaf litter. In quantitative sampling carried out during Project LLAMA, this species occurred in 4 of 100 miniWinkler samples at a lowland Chiapas site and in 7 of 100 samples from in and near Tikal National Park in Guatemala.

Identification:

Worker. HW 0.53–0.59 (n=5); mandible with three widely spaced denticles on masticatory margin, middle denticle largest; subapical tooth with minute reclinate denticle at base; subapical tooth about twice as long as apical tooth; intercalary teeth prominent, one closest to apical tooth about half as long as apical tooth; labrum subrectangular, outer margins diverging anteriorly, anterior margin very shallowly and evenly concave, with minute notch medially; posterior margin of clypeus elevated above anterior face; arcuate grooves and ridges of face very shallow; mesosomal dorsum evenly and shallowly convex in profile, metanotal groove not or very weakly impressed; propodeal tooth obtuse to right angled, infradental lamella broad and descending almost perpendicularly from tooth; about 12 squamiform setae on posterior half of first gastral tergite. The queen and male are unknown.
