(Holotype and 5 paratype and non-type workers were measured.) Body dark reddish brown; legs with similar coloration as body, but often slightly paler; mandible light brown. Body with erect hairs; pubescence dense on frons, pronotum and gastral tergites. Clypeus faintly punctate; frons extensively rugoso-punctate, but area around antennal insertion finely rugose; vertex of head (including occipital lobe) smooth. Anteriormost part of pronotum transversely rugose, and remainder smooth to weakly punctate; dorsal face of mesonotum weakly rugose; lateral face of mesosoma rugose more or less longitudinally; mesopleuron, metapleuron and lateral face of propodeum smooth or weakly punctate; dorsum of propodeum weakly rugoso-punctate transversely. Frontal sulcus faint, reaching median ocellus; anterior clypeal margin concave; mandible with 8 teeth that reduce in size from apical to basal teeth; two denticles present between first and second teeth; palp formula 6,4; orbital groove absent; scape slightly shorter than funicular segments combined; funicular segments each longer than broad. Pronotum in lateral view flattened dorsally; propodeum in lateral view roundly convex posterodorsally.
