Taipan process on the arch of the palate, which Kinghorn noted separated the genus from all other elapids. The three known species are: the coastal taipan ("Oxyuranus scutellatus"), the inland taipan ("Oxyuranus microlepidotus"), and a recently discovered third species, the Central Ranges taipan ("Oxyuranus temporalis"). The coastal taipan has two subspecies: the coastal taipan ("O. s. scutellatus"), found along the northeastern coast of Queensland, and the Papuan taipan ("O. s. canni"), found on the southern coast of Papua New Guinea. A 2016 genetic analysis showed that the speckled brown snake was an early offshoot of a lineage giving rise to the
Inland taipan taipan is dark tan, ranging from a rich, dark hue to a brownish light-green, depending on season. Its back, sides and tail may be different shades of brown and grey, with many scales having a wide blackish edge.
