Habit:

Description of adults: Examined: Description by Gibbs & Kristensen (2011). Forewing length: : 3.2 mm. Vestiture of hair-like scales on head black on vertex, creamy-white on frons; antennae black throughout; 3334 flagellomeres in female with basal 11 scale-covered; piliform scales on scape and pedicel black; thorax and tegulae black; mesonotum black-scaled with bronzy iridescence; forewings black-brown with silvery-white markings: claval mark missing; a very narrow, slightly convex median fascia; an incomplete postmedian fascia from costa to half; a large apical spot; all coxae ventrally with black scales; hindfemora greyish; fore and midtibiae black with whitish band at 0.5; tarsi black with whitish bands at proximal ends of tarsomeres 1, 2 and 3, except that hindtarsomere 1 is entirely black.

Distribution:

The species is known only from the type locality at Karkloof Falls, near Howick in South Africa (Gibbs & Kristensen 2011), in a height of appr. 1020 m a.s.l. (Kurz & Kurz 2020).

Biology:

The imagines fly amongst ferns and seedlings on a steep slope under a thin, low, exotic canopy (Gibbs & Kristensen 2011). They are on the wing in February (Kurz & Kurz 2020).

postabdomen and genitalia: "Segment V gland 0.4 mm diam., with about 10 long fluted scales. Genital segments with segment X approximately equidimensional, lateral sclerites C-shaped with anterior edge emarginated. Papilla large (0.12 mm deep), approximately equidimensional with its antero-ventral edge strongly reflexed into the bursa, dorsal margin deeply cut away; thick-walled proximal ductus section of spermatheca with its bulbous end about half diameter of ductus length, thin-walled mid-section of utriculus shorter than the ductus, anterior sac of utriculus 0.1 mm diameter" (Gibbs & Kristensen 2011).
