Habit:

Description of adults: Examined: Description of Gibbs & Kristensen (2011). Forewing length 3.0 mm, 3.43.5 mm. Vestiture of hair-like scales on head ochreous with darker tips; piliform scales on scape and pedicel black; antennae black, with 43 flagellomeres in male and 3233 in female; thorax and tegulae black, mesonotum with golden iridescence; forewings black-brown with distinct silvery-white markings: a slightly bent claval mark, angled towards dorsum; an almost straight, uninterrupted median band and a small triangular remnant of the postmedian band from costa to about half of wing width; subapical band absent; all coxae ventrally black; hindfemora greyish; fore and midtibiae black on dorsal surface, white beneath with a white band at 0.5; all tarsi black with whitish bands at proximal ends of tarsomeres 1, 2 and 3, except that tarsomere 1 is entirely black on hindleg.

Distribution:

The species is known only from Hogsback, in the Eastern Cape province of South Africa (Gibbs & Kristensen 2011). Here, it occurs in a height of appr. 950-1200 m a.s.l. (Kurz & Kurz 2020).

Biology:

The species, predominately females, are found in tall dense rainforest, on clearings and margins where the forest floor is damp. The specimens fly around annuals and ferns in one generation per year in February (Gibbs & Kristensen 2011, Kurz & Kurz 2020).

genitalia. "Sternum VIII remnants large, trapezoidal, lying closely adjacent to anterolateral edge of vinculum, bearing about 16 small setae. Anteroventral margin of IX sclerotisation broadly rounded and thickened. Median plate narrow, tapered at anterior end with a distinct ventral keel, strongly darkened anteriorly. Valvae of moderate length, with their curvature markedly angled (ratio length:width 4.0). Tegumen lobes with an irregular un-sclerotised patch anteriorly along the mid-dorsal line. A cluster of about 40 hair-sensilla on the membraneous dorsum of IX. Phallus elongate, ratio length:height 5.6; aedeagus with a constricted neck region in dorsal view; gonopore heart-shaped, small, less than half width of aedeagus; ventral bulb moderate" (Gibbs & Kristensen 2011).

postabdomen and genitalia. "Segment V gland 0.4 mm diam., with about 12 long fluted scales. Segment X equidimensional, the sclerites rounded, often emarginated along the anterior edge. Papilla goblet-shaped with its thick walls strongly reflexed around the anterior margin; thick-walled proximal section of spermatheca with its bulbous end about half the diameter of ductus length, thin-walled mid section of utriculus about the same length as ductus, anterior sac of utriculus 0.08 mm diameter" (Gibbs & Kristensen 2011).

Diagnosis:

The species is characterized by the absence of the forewing subapical band.
