Worker
Kempf (1951) - 4.0 mm. Median head length 1.05 mm; Weber's length of thorax 1.22 mm. Black; the following ferruginous: tip of mandibles, frontal carinae, tip of scape, first funicular segment, tip of femora, tibiae, fore tarsi, 2-4 middle and hind tarsi, anterolateral crest of gaster. Tip of thoracic and peduncular spines rufous brown.

Head subopaque. Mandibles finely reticulate-punctate and rugulose. Frontal carinae without crenulate border, beset with projecting setulae on the anterior half, the setulae arising from above. Posterior portion of frontal carinae slightly diverging caudad, and strongly sinuate, emarginate in front of, convex and upturned above, the eyes, a few erect setae above the eyes. Eyes prominent, their maximum diameter longer than 1/3 of median head length. Occipital corners obliquely subtruncate, the occipital border evenly concave. Cheeks strongly marginate beneath, very densely scaled. Upper surface of head scarcely convex, very finely and densely reticulate-punctate, sparsely covered with simple, appressed, flattened, silvery hairs, which became canaliculate and situated in more or less excavated grooves in front of the occipital border.

Thorax subopaque. Pronotum with a tridenticulate crest on each side. Mesonotum with an acute lateral tooth. Promesonotal and mesoepinotal sutures obsolete. Basal face of epinotum with a pair of small teeth near the anterior corner and a third tooth on the posterior corner, the posterior border of which is prolonged behind in a crest, delimiting the declivous face laterad and behind, as in simillimus. Upper surface of thorax finely reticulate-punctate, with scattered longitudinal grooves, each containing a decumbent, silvery canaliculate scale. Laterotergite of pronotum longitudinally striated. Sides of thorax finely reticulate with sparse, simple, appressed setae. Femora incrassated, somewhat compressed, angulate above at the half. Basitarsi slender, not conspicuously flattened and broadened at base.

Petiole subopaque, the anterior face truncate, with a strong lateral somewhat recurved spine. Postpetiole as long as petiole, with a slightly shorter, lateral spine, curved forward at base, slightly recurved at apex. Sculpture of both peduncular segments as on upper surface of thorax.

Gaster subopaque, oval. Greatly emarginate mesad in front, distinctly crested antero-laterad, the crest extending hackward over more than half of the sides of the first gastral tergite, fading out shortly in front of the apical third. Upper surface of gaster finely reticulate-punctate, rather densely covered with mostly simple, silvery appressed scales, lying in shallow grooves. Erect pile confined to tergites 2-4 and the apical border of sternite I and the following sternites.
