Apicoscrobal hair flagellate; margin anterior to this with stoutly spatulate curved hairs. Leading edge of scape with spatulate curved hairs. Cephalic dorsum with short, narrowly spatulate ground-pilosity that is inclined anteriorly; occipital margin with a transverse row of 4-6 poorly defined specialised hairs that are not spatulate and are only slightly longer and slightly more elevated than the ground-pilosity. Eye with 6 ommatidia in total. Pronotal humeral hair flagellate and very long. Promesonotal dorsum superficially punctate; propodeal dorsum smooth. Pronotal dorsum with a pair of sub flagellate erect hairs; mesonotum with a similar pair of hairs anteriorly, and posteriorly with two pairs of shorter erect fine simple hairs. Hind femur dorsally, laterally and ventrally with numerous erect simple hairs; hind tibia probably also with similar pilosity at least on dorsal (outer) surface, but not apparent in holotype, which may be abraded. Propodeal tooth vestigial, represented only by a ghostly vestige at top of lamella. Lateral spongiform lobe of petiole in profile extends across about posterior half of side of node. Disc of postpetiole smooth. A pair of (may originally have been a row of 4) long sub flagellate standing hairs near base of first gastral tergite; remaining hairs much shorter, simple and fine, acute apically. Basigastral costulae restricted to limbus, not present on tergite proper.
