Zenodorus orbiculatus, the round ant eater, is a species of ant-hunting jumping spider found in Australia.

[1][2] The species was first formally named by Eugen von Keyserling in 1881 as Hasarius orbiculatus.

[1] Zenodorus orbiculatus are dark brown to black, with pale markings on the carapace behind the eyes, a circular pattern on the abdomen with a dot in the centre, and a pale band on the femur of each leg.

The species is widespread and abundant in Queensland, scattered throughout the remainder of Australia.

[2] The food preference is ants, but they also consume other spiders and insects.
