Key to Pheidole majors of Borneo

This worker key is based on: [[Media:Eguchi 2001a.pdf| Eguchi, K. 2001a. A revision of the Bornean species of the ant genus Pheidole (Insecta: Hymenoptera: Formicidae: Myrmicinae). Tropics Monograph Series. 2:1-154. PDF]]

Because the major of P. gombakensis sp. nov. has not been collected from Borneo, the major from Ulu Gombak, southern Malay Peninsula are used for making the keys “A” and “C.”
