The pygmy mulga snake (Pseudechis weigeli), also commonly known as the pygmy king brown snake, is a species of venomous snake in the black snake genus Pseudechis in the family Elapidae. The species is native to Australia.
In Australia, P. weigeli is endemic to the Kimberley ranges. The preferred natural habitats of P. weigeli are forest and savanna. P. weigeli is ovoviviparous. P. weigeli was genetically confirmed as a distinct species in 2017. Within the genus Pseudechis it is most closely related to the eastern dwarf mulga snake (P. pailsei) and an as yet undescribed species from the Northern Territory.
The specific name, weigeli, is in honor of Australian herpetologist John Randall Weigel (born 1955). Cogger HG (2014). Reptiles and Amphibians of Australia, Seventh Edition. Clayton, Victoria, Australia: CSIRO Publishing. xxx + 1,033 pp. ISBN 978-0643100350.

With luck
About 10% of wildlife watchers report a Weigel's Black Snake sighting in Kakadu National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 48th most-seen of the 54 reptiles we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
November
In that month about 40% of wildlife watchers report a Weigel's Black Snake in Kakadu National Park on a given day, against under 5% in June, August–October and December–April, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Weigel's Black Snake sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
2nd of 2
Of the 2 parks where we can rate Weigel's Black Snake sightings, Kakadu National Park ranks 2nd at about 10%. The best odds are in Litchfield National Park (Australia, about 30%).
GBIF citizen-science records
It is estimated from how often the Weigel's Black Snake is recorded against all the reptiles logged in Kakadu National Park (5 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
