Posterior head margin weakly to moderately concave. Anterior clypeal margin medially impressed. Frontal carinae strongly developed, diverging posteriorly, and ending at corners of posterior head margin. Antennal scrobes weakly developed, shallow, narrow, and without defined posterior and ventral margins. Antennal scapes comparatively short to moderately long, not reaching posterior head margin (SI 81-84). Eyes small (OI 17-19). Mesosomal outline in profile flat to weakly convex, moderately marginate from lateral to dorsal mesosoma; promesonotal suture and metanotal groove absent; mesosoma comparatively stout and high (LMI 38-45). Propodeal spines extremely long, spinose, and acute (PSLI 58-63); propodeal lobes short, triangular, and blunt. Petiolar node in profile rectangular nodiform with comparatively rounded angles, around 1.1 to 1.3 times higher than long (LPeI 79-86), anterior and posterior faces approximately parallel, anterodorsal and posterodorsal margins approximately at same height, dorsum straight to weakly convex; node in dorsal view around 1.1 times longer than wide (DPeI 87-93). Postpetiole in profile subglobular, approximately 1.1 to 1.2 times higher than long (LPpI 83-91); in dorsal view feebly wider than long (DPpI 101-105). Postpetiole in profile appearing a bit more voluminous than petiolar node, in dorsal view approximately 1.2 to 1.3 times wider than petiolar node (PPI 118-127). Mandibles distinctly longitudinally rugose; clypeus with four to six longitudinal rugulae, median rugula better developed than lateral rugulae; cephalic dorsum between frontal carinae with eight to ten longitudinal rugae, most rugae running unbroken from posterior head margin to posterior clypeus, rugae never with cross-meshes; lateral and ventral head longitudinally rugose with very few cross-meshes. Mesosoma laterally and dorsally distinctly longitudinally rugose, rugae laterally more irregularly arranged. Forecoxae mainly reticulate-punctate with superficial, superimposed rugulae. Waist segments with reticulate-rugose to longitudinally rugose sculpture. Ground sculpture everywhere on body faint to absent. First gastral tergite unsculptured, smooth, and shining. All dorsal surfaces of head, mesosoma, waist segments, and gaster with abundant, long, and fine standing hairs. First gastral tergite without appressed pubescence. Anterior edges of antennal scapes with subdecumbent to erect standing hairs. Body of uniform very dark brown to black colour.</paragraph>
