diagnosis A member of the fallax   HNS group, similar to bergi   HNS in some traits, but easily distinguished from it and other group members as follows.

Major: brownish yellow with a conspicuous circular brown spot in center of vertex, and yellow appendages. Propodeal spines thin, one-third as long as the basal propodeal face and vertical to it; petiolar node very high, tapering in side view at the apex to form a blunt point; postpetiole from above elliptical, with subangulate lateral margins; rugoreticulum extending on each side of head from eye to antennal fossa; carinulae along midline reach from vertex to occiput, and flanked on occiput by short, feeble carinulae, with rest of posterior half of dorsal head surface smooth.

Minor: propodeal spines long and thin; occiput narrowed, with nuchal collar; carinulae cross border between mesopleuron and side of propodeum.

Measurements (mm) Holotype major. HW 1.14, HL 1.22, SL 0.64, EL 0.14, PW 0.56. Paratype minor: HW 0.52, HL 0.64, SL 0.68, EL 0.12, PW 0.34.

Color Major: body and mandibles light brownish yellow, verging to light brown in a circular spot in center of vertex; appendages clear yellow.

Minor: body brownish yellow, tending to clear yellow on mesosoma and waist, with a brownish tinge on head and gaster; appendages clear yellow.
