Description
DIAGNOSIS An unusual species that mixes traits of the tristis and flavens groups, and is tentatively placed in the former.
Major: postpetiolar node from above very wide, bell-shaped; mesonotal convexity rudimentary; propodeal spine broad, and equilaterally triangular; petiolar node in side view tapered to a point; occiput narrower than anterior clypeal border; pilosity very sparse.
Minor: all of body except frontal triangle, mid-clypeus, and gaster foveolate and opaque; humerus subangulate in dorsaloblique view; propodeal spines reduced to denticles; petiolar node in side view tapered to a blunt point; pilosity very sparse.
MEASUREMENTS (mm) Holotype major: HW 1.36, HL 1.46, SL 0.64, EL 0.20, PW 0.66. Paratype minor: HW 0.54, HL 0.62, SL 0.58, EL 0.10, PW 0.34.
COLOR Major: body concolorous medium reddish brown, legs light reddish brown.
Minor: body medium yellowish brown (head darker than rest), legs light yellowish brown.
