Original decription, Turner 1898
Xylorycta melaleucae, n. sp. Male, 17-18 mm.; antennal  ciliations, ¼. Head, face, palpi, and antennae whitish-grey. Thorax grey. Abdomen ochreous. Legs whitish; anterior pair infuscated. Forewings elongate, costa rather strongly arched near base, thence straight, apex round-pointed, hindmargin obliquely rounded; fuscous-grey, irrorated with dark fuscous scales; a broad snow-white streak along costa near base, ceasing rather abruptly beyond middle; some dark suffusion in basal part of disc; two fuscous dots placed transversely in disc at 2/3; hindmarginal edge barred with fuscous and whitish; cilia dark fuscous; some white scales about middle of hindmargin. Hindwings and cilia pale-grey.
Coomera River, Moreton Bay: two specimens from tunnelling the stems of Melaleuca genistifolia. The specimens were unfortunately considerably damaged, so that the description may not be accurate as to finer details.

Food plants: Larva boring in stem. Larval foodplant: Melaleuca genistifolia (Myrtaceae). (Edwards, 2003).
Flight period:
Distribution: New South Wales, Queensland. Endemic. (Edwards, 2003).

Remarks: The male genitalia suggest that this species belongs to the Lichenaula group. Simple, brushlike heavily ciliated claspers without terminal hooks are a diagnostic feature of this group.
