Tetracona amathealis is a species of snout moth in the subfamily Spilomelinae of the family Crambidae. It was described by Francis Walker in 1859 based on material collected at Moreton Bay in Queensland, Australia.[1] It is found in New Guinea and Australia, where it has been recorded in Queensland, northern New South Wales and Western Australia.[2] The species was formerly placed in the genus Agrotera, but in a recent taxonomic revision it was transferred back to the re-instated genus Tetracona, of which it is the type species.[3]
The wingspan is about 20 mm.
The caterpillars feed on Eucalyptus tereticornis, a plant of economic interest, which is why T. amathealis is sometimes considered a pest species.[2]
