Synonymic description, T.P. Lucas 1901
Lichenaula sternoides, nov. sp.
♂ 20 mm. Head white. Palpi white, fuscous at the tip.
Antennae very fine fuscous and white annulated. Thorax white with cuprous fuscous narrowly on either side. Abdomen white. Forewings gently dilate, costa rounded, hindmargin obliquely rounded, snow white, with cuprous fuscous markings; a clubbed fascia from base to ¼ inner margin, includes a thin strip of ground-colour along inner margin, and terminates in a clubbed head on inner margin; a broad fascia from base, on costal side of first fascia; costa, runs along centre of wing, becoming dilate but not touching; and abruptly truncate posteriorly, a suffusion unites this with a broad oblique fascia from posterior third of its costal border extending to between 3/6 and 4/6 costa, thence diffused outwardly to middle of hindmargin; there is a small black discal spot in this diffusion; this spot subtends a small blotch which suffuses towards inner margin with surrounding  fascia; a broad apical blotch, also diffused. Cilia white, tinged opposite marks with coppery fuscous. Hindwings light smoky fuscous. Cilia smoky fuscous. One specimen at light, May Orchard, Brisbane. A very strongly-marked species.
