Uromycladium tepperianum is a rust fungus that infects over 100 species of Acacia and related genera including Paraserianthes in Australia, south-east Asia, the south Pacific and New Zealand.

[7][8] The fungus is present in Australia, Philippines, Malaysia, Indonesia, Timor Leste, and New Zealand.

[citation needed] It was introduced deliberately to South Africa for biological control.

[citation needed] The galls of Uromycladium tepperianum have been reported to be used by moths in the families Gracillariidae, Tortricidae, Tineidae, Pyralidae, and Stathmopodidae as food sources and domatium for their larvae in Australia.

Erechthias mystacinella and Opogona comptella moth larvae from the family Tineidae have been reported to live and feed on the inside of U. tepperianum galls.
