Twenty-five genera with 344 species were described world-wide in 2006. In Australia one can find about 32 species.

Genus Thasyraea

Thasyraea lapida
Thasyraea lepida

Two species in this genus. Thasyraea ornata and Thasyraea lepida.
They resemble the European Tibellus oblongus, a small huntsman.
To complicated things, many guides show this spider as Tibellus tenellus which has a more squared off head, and smaller eyes, wider apart.

But the hairs combed in a point between the front eyes are characteristic for Thasyraea
