![]() Ontogenetic colour changes, suggestions of intergrades, and possible hybridisation with other Pseudonaja species added to the confusion. The most easily-observed difference between mengdeni and nuchalis is that the rostral scale in nuchalis is long and strap-like, and the snout appears squared-off from above, whereas in mengdeni the rostral is not particularly elongated and the snout is more rounded.Western Brown Snakes may also be confused with another large brownish-coloured snake, the unrelated Mulga Snake Pseudechis australis, however Mulga Snakes tend to have a broader head and “heavier” build (particularly larger specimens), and never show any sort of banded pattern.įor many years it was suspected that the widespread Western Brown Snake ( Pseudonaja nuchalis) was in fact a composite species, however efforts to split nuchalis were largely defeated by the extreme level of colour and pattern variation encountered both within and between populations. nuchalis by its lighter coloured mouth (blackish in both mengdeni and nuchalis). Within the Western Brown Snakes Pseudonaja aspidorhyncha may be differentiated from Pseudonaja mengdeni and P. Close examination is often necessary (generally not recommended when live!) to make a positive identification. Western Brown Snakes overlap in distribution with a number of other snakes that are similar in appearance, particularly other species of brown snake ( Pseudonaja spp.).
