Description

Worker

Holotype. TL 4.7, HL 1.20, HW 0.76, CI 63, ML 0.62, MI 52, SL 0.66, SI 87, PW 0.46, AL 1.22. Spiniform distal preapical tooth located at about one-third the mandible length from the apicodorsal tooth, the small proximal preapical tooth located just proximal of the midlength; distal tooth less than 5 times longer than proximal tooth. Distance between apicodorsal tooth and distal preapical tooth slightly less than distance between distal and proximal preapical teeth. Anterior clypeal margin shallowly concave. Propodeal teeth very small, only slightly larger than proximal preapical tooth on mandible. With petiole in profile the node subclavate, without a differentiated anterior face; instead the peduncle joins the dorsum through a long shallow evenly convex curve. Petiole node in dorsal view thickening from front to back, much longer than broad. Head with a pair of erect hairs at highest point of vertex; with short spatulate ground-pilosity distinct. Dorsal surfaces of promesonotum and petiole with short spatulate ground-pilosity. Cephalic dorsum coarsely reticulate-punctate anteriorly; reticulate-punctate with superimposed reticulate rugulae posteriorly. Promesonotal dorsum coarsely punctate.
