DistributionAustralia (New South Wales, Northern Territory, Queensland, South Australia, Western Australia)

Type locality: Port Essington, N.T., Australia Map legend:
TDWG region - Region according to the TDWG standard, not a precise distribution map.

NOTE: TDWG regions are generated automatically from the text in the distribution field and not in every cases it works well. We are working on it.
TypesHolotype: BMNH 1946.1.20.39
Holotype: AM R31927, from Port Darwin, N. T. [Pseudechis darwiniensis].
Holotype: none; description based on literature records (see also under Pseudonaja textilis Duméril, Bibron and Duméril, 1854), from "Murray River", N. S. W. /Vic. [Pseudechis cupreus].
Holotype: not found, from Eradu, W. A. [Pseudechis denisonioides].
Holotype: NMV D12355, from East Alligator River, Arnhem Land, N. T. [Pseudechis platycephalus].
Holotype: SAMA R3151, from Mount Wedge, near Elliston on the W coast of Eyre Peninsula, S. A. [Denisonia brunnea]. 
CommentSynonymy partly after COGGER 1983. Wüster et al. (2004) consider Pailsus rossignolii and Pseudechis weigeli as a valid species based on DNA sequence divergence. However, further studies are required to confirm their species status. KAISER et al. rejected all names coined by HOSER in or after 2000.
