The reptile was about one metre long but, because taipan species are among the most venomous snakes in the world, Hutchinson did not inspect the creature on site. He bagged the snake and sent it, along with others captured from the trip, to the Western Australian Museum

It is the first new taipan species to be discovered in 125 years. It was not until two weeks later that the new species was studied.

At first, it was tentatively identified as a western brown snake because of the similar size and colouring. However, several weeks later, WA Museum reptile collection manager Brad Maryan noticed the now preserved snake had a large, pale head similar to the coastal taipan.

New Species

Oxyuranus temporalis differs from its two congeneric species Oxyuranus scutellatus and Oxyuranus microlepidotus in lacking a temporolabial scale and having six rather than seven infralabial scales. Phylogenetic analysis of mtDNA sequences showed it to be the sister species of the two previously known taipans.

The two described species of Oxyuranus are among the most venomous land snakes in the world - Oxyuranus microlepidotus ranked the most venomous land snake and Oxyuranus scutellatus, the third most venomous after Pseudonaja textilis.

The Central Ranges Taipan or Oxyuranus temporalis is likely to be extremely venomous given its close relationship to the other two species. The new species is known from the single specimen, so very little is known of its natural history, and nothing of its venom.

The adult female taipan measuring 1.3 metres, was captured by the Spinifex people from the Tjuntjuntjara Aboriginal community during a biological study at Ilkurlka, 165 kilometres west of the South Australian border. The second snake was found 425 kilometers south of the location of the initial discovery.
