Hadronyche adelaidensis
Adelaide Funnel-Web Spider Identification
South Australian funnel-web from the Gulf-region species group, unusual among funnel-webs for constructing a trapdoor burrow.
Medical emergency potentialThe Adelaide funnel-web belongs to an isolated South Australian Hadronyche group adapted to drier Gulf-region forests. Its trapdoor-building burrow is unusual for an Australian funnel-web, but the spider should not be identified from a door alone because trapdoor spiders also occur in the same broad region.
Quick identification
- Dark robust Hadronyche-type build
- South Australian Gulf-region range clue
- May construct a trapdoor burrow unlike most funnel-webs
- Easily confused with local idiopid trapdoor spiders
What to check next
Use range and burrow structure only as supporting clues. Do not open or probe the burrow, and leave species confirmation to an arachnologist.
When to seek medical help
Treat a suspected funnel-web bite as an emergency. Call 000, keep the person still and use pressure immobilisation if trained and available.
Where it is usually seen
Drier forest and sheltered soil habitats in the Gulf region of South Australia, where the spider occupies a silk-lined trapdoor burrow.
