Australian Flattie Spider Karaops Identification

Extremely flattened, quick wall-and-bark hunter in the Australian genus Karaops, often mistaken for a small huntsman.

Usually low risk

Australian flatties are selenopid spiders in the genus Karaops. Their body is remarkably thin and their legs radiate sideways, allowing them to shelter under bark or rock. Many species have limited ranges and need microscopic examination, so genus level is the useful cautious endpoint for ordinary photographs.

Quick identification

  • Exceptionally thin, flattened body
  • Legs radiate sideways in a near-circular outline
  • Very fast movement across bark, rock or walls
  • Often hides in cracks and has no capture web

What to check next

Compare huntsmans: a flattie is usually smaller and even more wafer-thin. Do not guess a Karaops species because many are range-restricted and externally similar.

When to seek medical help

Usually low risk, but avoid handling. Seek medical advice for severe pain, allergy symptoms or worsening symptoms after any bite.

Where it is usually seen

Under bark and rocks, in narrow crevices, on exposed rock faces, walls and sheltered structures across much of mainland Australia.
