Key to Philippine Leptanillinae
This worker key is based on: General, D. and G. Alpert. 2012. A synoptic review of the ant genera (Hymenoptera, Formicidae) of the Philippines. ZooKeys. 200:1-111 doi: 10.3897/zookeys.200.2447.
These ants are tiny, requiring higher magnification for observation of these character states. The genus Protanilla is included because of unconfirmed reports that it has been collected in Palawan Island.
