Inland taipan South Wales, and William John Macleay described the same snake under the name "Diemenia ferox" (thinking it was a different species). No more specimens were collected until 1972. In 1896 George Albert Boulenger classified both as belonging to the same genus, "Pseudechis" (black snakes), referring them as "Pseudechis microlepidotus" and "Pseudechis ferox". In 1956, relying only on published descriptions and notes, James Roy Kinghorn regarded "ferox" as a synonym for "microlepidotus" and proposed the genus "Parademansia". In 1963 Eric Worrell considered "Parademansia microlepidotus" and "Oxyuranus scutellatus" (coastal taipan, named simply "taipan" in those days) to be the same species. In
Taipan taipans, with the central ranges taipan being an offshoot of the common ancestor of the inland and coastal taipans. Their diets consist primarily of small mammals, especially rats and bandicoots. Species of this genus possess highly neurotoxic venom with some other toxic constituents that have multiple effects on victims. The venom is known to paralyse the victim's nervous system and clot the blood, which then blocks blood vessels and uses up clotting factors. Members of this genus are considered to be among the most venomous land snakes based on their murine , an indicator of the toxicity on mice. The
