Tasmania has its fair share of spiders, the most dangerous being the redback and Lake Fenton trapdoor spiders, whose bites are quite deadly. While certain species of spiders like the mouse spiders are almost wholly absent here, there are several species endemic to this state. These include the Tasmanian cave spider, Plomley’s trapdoor spider, and the Tasmanian red and black spider.
Recently, a young boy named Murphy Widdowson discovered a new species of wolf spider. The spider’s scientific name, Artoriopsis murphyi, was coined in his honor.

Frequently Asked Questions
The most dangerous spiders in Tasmania are the redback spider and the Lake Fenton trapdoor spider. Both species possess medically significant venom, and their bites are considered potentially deadly. Immediate medical attention is crucial following a suspected bite from either of these spiders to ensure proper and timely treatment.
Yes, several spider species are endemic to the state, meaning they are found nowhere else. These unique spiders include the large Tasmanian cave spider, Plomley’s trapdoor spider, and the Tasmanian red and black spider. The recently discovered wolf spider, Artoriopsis murphyi, is also a notable local species.
The biggest spider found in Tasmania is the Tasmanian cave spider (*Hickmania troglodytes*). This large, primitive spider is found exclusively in the state’s cave systems and other dark, humid environments. Its significant leg span makes it the most physically imposing arachnid native to the island state.
Yes, a type of funnel-web spider is native to Tasmania. The Lake Fenton trapdoor spider (*Plesiothele fentoni*) is a dangerous funnel-web species found in the region. Its bite is considered highly venomous and potentially deadly, making it one of the most medically significant spiders on the island.
No, mouse spiders are almost wholly absent from Tasmania. While these spiders are found on mainland Australia, they are not considered part of Tasmania’s native arachnid population. This absence is a distinct characteristic of the island’s unique fauna when compared to the rest of the country.
The black house spider is one of the most common spiders found in and around Tasmanian homes. This species often builds its distinctive lacy webs in window corners, under eaves, and in other sheltered crevices. While its bite can be painful, it is not typically considered dangerously venomous.
Huntsman spiders in Tasmania are considered less venomous compared to species like the redback. While a bite from a huntsman can be painful and cause localized swelling due to their large fangs, their venom is not dangerously toxic to humans. They are generally reluctant to bite unless provoked.
