Number: 497, Pages: 15 - 20
The ant Stictoponera pertusa Lattke, 2004 (Formicidae: Ectatomminae) is recorded for the first time from Sumatra, Indonesia. The specimens have been collected from the leaf-litter of the lowland disturbed forest in West Sumatra Province. Dealate queen is described and illustrated for the first time. This species is easily distinguished from congeners by following features: head in frontal view with swollen base of mandible; clypeal lamella translucent, with broadly convex anterior margin; petiole in lateral view with propodeal declivity sharply defined laterally by low crests; subpetiolar process subquadrate with sharp posterior angle in lateral view.
