The species of the genus Plagiopholis are found in Southeast Asia, China and Taiwan.[3][4][5][6][7] The snakes of this genus are mountainous species that can be found in grasses and bushes. They feed primarily on earthworms, frogs, and arthropods (Zhao 2006). All species are oviparous, meaning they use internal fertilization to lay eggs.[8] Plagiopholis species can be distinguished from other genera in the subfamily Pseudoxenodontinae by their lower midbody scale count, entire anal plate, and smaller size (O'Shea 2018).
Nota bene: A binomial authority in parentheses indicates that the species was originally described in a genus other than Plagiopholis.
