Occipital margin feebly concave, sides of head parallel, occipital corners moderately rounded. Frontal carinae directed to occipital corners [presumably reaching beyond level of eyes]. Scape failing to reach occiput by 2 x apical width. Eyes moderately large, in front of midlength of head. Propodeal spines triangular, acute, somewhat elevated; in dorsal view about as long as the distance separating them. Metapleural lobes twice as long as spines, triangular and acute. Petiole in profile with node rectangular, in dorsal view the node longer than broad. Postpetiole about 1.5 x broader than petiole in dorsal view. Head and alitrunk sharply and extensively reticulate-rugose. Dorsum of head longitudinally rugose with about 10-11 components, the spaces between them punctate. Alitrunk reticulate-rugose dorsally, punctate laterally. Petiole punctate with some weak rugae, postpetiole coarsely and irregularly longitudinally rugose. Gaster unsculptured. Erect hairs short, moderately developed. Yellow-rust coloured, gaster and appendages paler, yellowish.
