Diagnosis Similar in various traits to chalcoides   HNS , mackayi   HNS , tennantae   HNS , and several species close to them (q.v.), differing as follows. Major: dark brown with bicolored head (see Color below); upper mesopleuron (anepisterum), dorsum of propodeum, and humerus covered by irregular, broken rugulae; lower mesopleuron (katepisterum), sides of propodeum, and most of anterior dorsal surface of head carinulate; middle of promesonotal dorsum in profde with a small, obliquely subangulate convexity; petiolar node in side view tapered toward apex; postpetiolar node from above oval.

Minor: mesopleuron and side of propodeum rugulose; most of head and all of pronotum smooth and shiny; occiput broad, its margin straight.

Measurements (mm) Holotype major: HW 1.08, HL 1.08, SL 0.62, EL 0.12, PW 0.52. Paratype minor: HW 0.56, HL 0.62, SL 0.56, EL 0.06, PW 0.36.

Color Major: body dark brown; head bicolored: strip of head capsule anterior to anterior margin of eyes brownish yellow, rest of capsule dark brown; appendages medium brown.

Minor: body blackish brown; head bicolored: narrow strip of the anterior half of head capsule between eye and anterior head capsule border a contrasting brownish yellow.
