2

 * Tibiae without erect setae. In minor worker, anterior margin of clypeus straight. Petiolar node narrowly rounded in lateral view => Camponotus stefanschoedli


 * Tibiae with erect setae. In minor worker, anterior margin of clypeus with short medial lobe. Petiolar node broadly rounded in lateral view => Camponotus javaensis
