Description
HW 0.61–0.69 (n=6); mandible without differentiated masticatory and basal margins, with six distinct teeth distributed from apex to base, fifth tooth equidistant between fourth and sixth (basal) tooth, and with a deep notch between sixth tooth and basal condyle; dorsal surface of mandible with several coarse longitudinal striae and several large piligerous puncta; in full face view, lateral clypeal teeth project from beneath: clypeal shelf; lateral clypeal teeth confluent with both anterior (ventral) margin of clypeus and transverse carina that forms clypeal shelf, forming vertices of concave triangular space on ventral face of clypeus; hypostomal tooth absent; compound eye composed of 7–8 ommatidia; face fully sculptured with reticulate rugae, with weak longitudinal orientation medially.

Short anterior face of pronotum well separated from dorsal face by a weakly elevated transverse ruga; dorsal profile of promesonotum and propodeum forming a single arched convexity, metanotal groove weakly impressed; propodeal spines pronounced, acute; space between propodeal spines a broad concavity without distinct dorsal and posterior faces, smooth and shiny with a few transverse rugae; rest of mesosoma strongly rugose, rugae wavy and generally longitudinally oriented; petiolar node subquadrate with strongly differentiated anterior, dorsal, and posterior faces; posterior face of petiolar node slightly concave and separated from dorsal face by distinct transverse ruga; petiole and postpetiole coarsely irregularly rugose; postpetiole in dorsal view about as long as wide, with straight anterior margin and evenly rounded posterior margin; gastral dorsum smooth and shining.

Scape with abundant long subdecumbent pubescence, and with one or two long suberect setae that are differentiated from the pubescence and project above it; clypeus and frontal carinae with long erect setae; posterior and posterolateral margins of head with long erect setae; mid and hind tibia with abundant long subdecumbent setae and about three differentiated erect setae that are longer than width of tibia; in profile, dorsal surfaces of head, mesosoma, and gaster with relatively sparse, long, erect setae; FSH about 0.11, FSI 0.16.
