Keys including this Species


Kohout (2008) - This is a very characteristic, relatively rare species that is known from both Java and Borneo. It was reported from Sulawesi by Emery (1901: 569) but the workers from Lore Lindu and Dumoga-Bone National Parks are the only specimens I have seen from the island.
