Kalicephalus burseyi n. sp. (Nematoda: Diaphanocephalidae) is described from a snake, Oxyrhabdium leporinum, on Luzon Island, Philippines. Unequal spicule length places the new species in the subgenus Kalicephaloides, which also includes Kalicephaloides bungari, Kalicephaloides longispicularis, and Kalicephaloides alatospiculus. Kalicephalus burseyi n. sp. has shorter spicules than K. longispicularis and longer spicules than in K. alatospiculus and K. bungari. The new species also differs from the other three species in details of the copulatory bursa morphology and some other features. The new species is the ninth member of the genus reported from the Philippines and the first Kalicephalus species found in O. leporinum.
