Hind-wings cleft firstly from 2/5, secondly from near base, segments linear; dark fuscous; anterior part of disc and most of third segment in ♂ deep ferruginous, in ♀ bright golden; cilia pale shining rosy, tinged with purplish-grey on costa and towards apex of first two segments.

Kovtunovich & Ustjuzhanin provided a redescription of the lectotype from Cairns, QLD, as follows[2]:

External characters of the lectotype. Head, thorax, and tegulae, light brown. The labial palpi are almost three times longer than the diameter of the eye and pointed like elephant tusks, their 3rd section being darker than the 2nd. Antennae dark-brown. Forewing length 11 mm. Wings bright reddish-brown. Forewing with yellow spots. Outer margin of both lobes concave. Fringe yellow inside the cleft, with patches of dark hair only at the tips of the lobe. The fringe along the hind margin of the forewing is yellow, with patches of dark hair situated under the base of the cleft and at the tip of the 2nd lobe. Hindwings plain reddish-brown; the 3rd lobe is half the length of the 2nd and there is no cluster of dark scales at the tip. Hind legs yellow, tarsi noticeably darkened.
