Original description, Meyrick 1915
Xylorycta ceratospila, n. sp.
♀. 14 mm. Head and thorax white. Palpi white, terminal joint dark fuscous except towards base. Abdomen whitish. Forewings elongate, costa gently arched, apex obtuse-pointed (?), termen faintly sinuate, oblique; 7 to termen, 8 to costa; white; markings rather dark fuscous; a blotch occupying basal half of dorsum and reaching half across wing, with a long wedgeshaped posterior projection reaching in disc to 3/5; a smaller semicircular blotch extending on dorsum from near beyond this to tornus, connected with it on dorsum; a very oblique straight streak from costa beyond middle to termen beneath apex; a browner streak along apical fourth of costa : cilia light greyish, with some slender dark fuscous bars at base, round apex suffused with white (imperfect), on costa white with two rather dark fuscous bars. Hindwings grey; cilia whitish-grey.
Queensland, Cairns, in November (Dodd); one specimen.

Food plants:
Flight period: November.
Distribution: Queensland. Endemic. (Edwards, 2003).

Remarks: Specimens of this moth in the ANIC collection have been misidentified as Iulactis semifusca. I am fairly certain that X. ceratospila belongs with other moths currently identified as Iulactis; alternatively, as Turner suggested, these moths may possibly belong to Plectophila. Many thanks to Patrick Strutzenberger whose type specimen photography at the BMNH has enabled this confusion to be clarified.
