Hoplocephalus is a genus of venomous snakes in the family Elapidae. The genus is endemic to Australia . Three species are recognized.

Description

Snakes of the genus Hoplocephalus have a pair of large grooved venom fangs, which are followed by two or three small maxillary teeth. The mandibular teeth are longest anteriorly. The head is distinct from the neck. The eye is rather small, with a round pupil. There is no loreal scale. The dorsal scales are smooth, without apical pits, and are arranged in 21 rows at midbody. The subcaudals are entire (undivided).[2]

The genus Hoplocephalus contains the following species which are recognized as being valid.[3]

  • Hoplocephalus bungaroides (Schlegel, 1837) – broad-headed snake
