Dimensions: HL 1.18-1.35, ML 1.14-1.29, HW 1.08-1.24, SL 0.72-0.77, ED 0.06-0.08, WL 1.63-1.88 mm, CI 0.92, MI 1.03-1.07, SI 0.62-0.67; n=3.

Cephalic dorsum reticulo-punctulate with short smooth and shiny median strip, bordered laterally by longitudinal carinae that extend from between frontal carinae and fusing at cephalic mid-length. Anterior cephalic margins with longitudinal parallel rugulae that diverge from antennal fossae. Frontal carinae separated by smooth and shining median depression, and also by small clypeal lobe. Head without gular teeth, only blunt corners present. Mandibles between dorsal carinae and teeth with oblique rugulae, becoming smooth and shining apicad. About 7 denticles on anterior clypeal margin. Mandibles with 2 separate ranks of teeth, a short apical tooth and a rounded preapical process. Eyes small and situated behind cephalic mid-length. Antennae 12-merous.

Promesonotal suture deep, mesometanotal suture also well defined; mesonotum narrow, transverse rugulose to punctate. Rest of nota tend to be smooth and shining, with sparse punctures.

Mesosoma laterally with anterior pronotal margin convex and broadly convex dorsally; metanotum straight; dorsal propodeal face slightly convex, declivitous face straight to slightly convex. Propodeal spiracle oval and directed lateroposteriorly. In dorsal view lateral pronotal margin and metanotum + propodeum form two broad convexities. Anepisternum with some longitudinal rugulae, but rest of lateral mesosomal sculpture as on dorsum, but with fewer punctures posteriorly. Declivitous propodeal face smooth and shining. Anterior nodal face of petiole straight to slightly concave, dorsal face broadly convex. Subpetiolar process an anteriorly directed rounded lobe with oval fenestra. Gaster smooth and shining with sparse punctures. Legs mostly smooth and shining, but with numerous punctures. Apex of protibia with pectinate spur, mesotibia with 2 simple spurs and metatibia with pectinate spur and simple spur.

Head, legs, antennae, and ventral mandibular face with abundant decumbent pubescence, thinner on rest of body. Suberect hairs on interior mandibular margin, antennae, and to a lesser degree on legs. Abundant subdecumbent hairs on tarsi. Sparse decumbent pilosity on mesosoma, gaster and longer suberect hairs on pygidium. Mandibles, antennae, legs reddish brown, rest of body black.
