Poecilipta species
Poecilipta Ant-Mimicking Spiders Identification in Australia
Tiny, fast ground-running ant mimics with slender legs. Poecilipta belongs to Corinnidae, not the jumping-spider ant mimics.
Usually low risk; avoid handlingAbout Poecilipta ant-mimicking spiders
Poecilipta are small corinnid spiders that resemble ants. Observations from inland eastern Australia describe very swift movement through wooded and semi-arid ground habitats. Some raise the front legs in an antenna-like pose. The slender body and quick stop-start movements are useful field clues, but other spider families have independently evolved a similar disguise.
A photograph needs to show a spider body and eight legs, rather than relying on the ant-like silhouette. Compare these ground runners with Myrmarachne-type jumping spiders and with Nyssus swift spiders. Large forward-facing jumping-spider eyes would point toward a different group. This page covers the genus: variation and incompletely described diversity make a single species name inappropriate from an ordinary phone photo. A short video can show movement more clearly than a blurred still. Do not disturb an ant colony or force the spider to move for a recording.
Identification limit: this guide is a comparison aid. A name match in the identifier does not establish a species record.

What to check next
Photograph the whole spider and its surroundings without disturbing it. Use the clues together; a close match is not a confirmed species identification.
When to seek medical help
For a suspected bite, contact the Poisons Information Centre on 13 11 26. Call 000 for breathing difficulty, collapse or other severe symptoms. Do not wait for an online identification.
Where it is usually seen
Ground, dry bark and leaf litter in Australian wooded or semi-arid habitats. Published field observations include NSW and Victoria; exact ranges differ among species.
