Original description, Lower 1892
Xyl. leucophanes, sp. nov.
Male and female, 24-30 mm. Head, thorax, and abdomen shining white. Abdominal segments obscurely reddish, anal tuft whiter Palpi above white, second joint beneath fuscous, except towards base. Antennae fuscous. Anterior and middle legs black, beneath white; posterior tibiae and tarsi pale-greyish-ochreous, slightly infuscated. Forewings oblong, hardly dilated costa gently arched on basal-half, thence straight, apex obtuse, hindmargin obliquely rounded; shining snow-white; costal edge blackish from base to near apex, posteriorly attenuated; cilia shining snow-white. Hindwings pale grey-whitish, darker towards apex; cilia shining snow-white, with a faint grey median line. Underside of wings smoky fuscous. Hind wings paler; cilia white.
Five specimens bred from Hakea rugosa, the larvae form conspicuous galleries of rough mud-coloured silk and refuse, and the imago emerge at intervals during December and January. Nearest to orectis, Meyrick. My specimens were obtained at Highbury; a remarkable coincidence is, that all the specimens emerged on consecutive Sundays, generally at about 7 p.m.

Other references

The adults of several shining white species are difficult to distinguish. These include X. leucophanes Low. from western Victoria and south-eastern South Australia, where the larvae live in tubular shelters among the foliage of Hakea (Protaceae) and feed off the leaves. (Common, 1990).
