Worker
Holotype (Paratypes n=2): HW 0.29 (0.29-0.31); HL 0.35 (0.35-0.37); SL 0.21 (0.20); PW 0.19 (0.18-0.19); WL 0.34 (0.29-0.32); GL 0.34 (0.29-0.35); TL 1.63 (1.15-1.27); CI 89 (81-82); SI 68 (67-69).

Diagnosis. Head larger than broad, sides convex and parallel, posterior border nearly straight. Mandibles with four teeth. Median portion of clypeus longitudinally bicarinate, the carinae diverging anteriorly. Frontal carinae short. A longitudinal and narrow stripe, smooth and shining, running from posterior medial margin of clypeus and between frontal lobes for about 40% of scape length. Basal half of scape narrow, then broadening into distal portion. Scapes ending at a distance from vertexal border. Eyes reduced to 2-3 ommatidia. Mandibles with 9 segments, club 2-segmented. The apical antennomere larger than funicular segments. Promesonotum nearly straight, bluntly marginated laterally. Pronotal groove absent, metanotal groove feebly marked laterally. In dorsal view mesosoma with two broad concavities at level of metanotal groove. Propodeum unarmed, dorsum very short sloping down to sloping face. Propodeal lobes narrow, lamellated. Propodeal spiracle circular, relatively larger, the orifice backward, spiracle low and close to posterior margin. Petiole with short peduncle, petiolar spiracle at level of the node. Petiole ventrally with a very tiny angle or teeth anteriorly. Gaster in dorsal view with medial portion concave and lateral angles well-marked. Sting well-developed and functional. Dorsum of head densely sculptured with shallow foveolated punctures whose diameters are greater than the spaces separating them; dorsum of promesonotum with irregular rugulae, most of them anteriorly; basal sloping face of propodeum with transverse rugulae; sides of mesosoma and petiole finely reticulated. Scapes, dorsum of head, promesonotum, petiole, postpetiole, gaster and tibiae with dense short and curved pubescence; long hairs (more or less three times larger than short hairs) few and distributed as follow: four in the clypeal area; two hairs from the anterior clypeal area projecting forward and outward; four in the anterior pronotal border; two posteriorly in the promesonotal dorsum; two in propodeal dorsum, two in the petiole, two in the postpetiole, none on first tergum. Light brown throughout.
