Description
From Wilson (2003): DIAGNOSIS A large, distinctive species of the tristis group with no clear affinities.
Major: head capsule in full-face view roughly circular in outline, with smoothly semicircular occipital lobes; carinulae originating along the midline of the dorsal half of the head turn outward; occipital lobes mostly smooth, with a sprinkling of foveae; antennal scape very short, its tip reaching the lateral head margin just posterior to the eye; entire clypeus, most of mesosoma, and dorsum of waist carinulate; anterior half of central strip of first gastral tergite shagreened; postpetiole cone-shaped.
Minor: occiput very narrow but lacks nuchal collar; part of propodeal dorsum and lower fringe of mesopleuron carinulate.
MEASUREMENTS (mm) Lectotype major: HW 2.16, HL 2.20, SL 1.00, EL 0.28, PW 1.04. Paralectotype minor: HW 0.74, HL 0.84, SL 1.00, EL 0.18, PW 0.48.
COLOR Major: body medium to dark reddish brown except for posterior half of head capsule, which is light reddish brown; appendages light reddish brown.
Minor: concolorous plain light brown.
Figure. Upper: lectotype, major. Lower: paralectotype, minor. Scale bars = 1 mm.
