Frontal lobes slightly expand- ed. Eyes moderately sized. Occipital mar- gin straight or feebly concave in full-face view. Fronotum unarmed. Propodeum with a pair of short to moderately long spines. Metapleural lobes triangular. Peti- ole node in profile high, higher than long, \vith the anterodorsal angle being an apex and the dorsum posteriorly rounding into the posterior surface, its anterior peduncle slightly longer than or about as long as the node.
