Description

From Wilson (2003): A member of the aberrans group — actually, an intermediate in habitus between the aberrans and tristis groups — distinguished as follows.

Major: large; head bicolored; occipital carina not present as in other aberrans-group species; hypostoma lacking spines; in full-face view, frontal lobes broad, asymmetrical, with pointed anterior borders that just reach the anterior clypeal border; humeri very large, rising 4X higher than the mesonotal convexity in dorsal-oblique view; acute, forward-projecting process on postpetiolar venter, as seen from the side; pronotum partly covered by transverse carinulae.

Minor: low process present on venter of postpetiole, as seen from the side; semicircular carinulae cover the pronotum; propodeal spines thin, needle-like.

MEASUREMENTS (mm) Lectotype major: HW 1.44, HL 1.76, SL 0.60, EL 0.16, PW 0.86. Paralectotype minor: HW 0.64, HL 0.68, SL 0.54, EL 0.12, PW 0.44.

COLOR Major: reddish yellow except for frontal lobes and borders of mandibles, which are a sharply contrasting blackish brown.
