Diagnosis. Species with grey upper surface and narrow forewings. The male genitalia are unlike those of any other known species, in particular from the wide, ear-like cucullus covered with long, robust and recurved setae, and the narrow and elongate sacculus.

Description. Wingspan 13 mm. Head white, ochreous-suffused dorsally. Antenna ringed white and brown; scape white dorsally, brown ventrally, with short, erect scales. Labial palpus whitish-brown on inner side, brown outside; second article 0,5 longer than third. Haustellum well developed. Forewing slender, grey with irregularly scattered dark scales; costal cilia dark grey, dorsal cilia light ochreous. Hindwing light ochreous grey; cilia coloured as on forewing. Abdomen grey.

Male genitalia ( Figs. 19, 21 View FIGURES 19–21 ): Gnathos knob globular. Tegumen medially constricted, pedunculus well dilated on outer side. Transtilla ribbon-shaped, narrower at apex. Valvula trapezoidal, with ventral edge linear, more sclerotized. Cucullus large, ear-shaped, covered with many long and recurved setae. Sacculus triangular, curved and with small tooth on dorsal angle. Phallotheca short and conical. Cornuti numerous, of varied lengths, gathered in long bundle.

Female genitalia: Unknown.

Abdominal structures ( Fig. 20 View FIGURES 19–21 ): No posterior lateral struts, transverse strut very characteristic, crescent-shaped with hooked sclerotized edges, proximal edge straight and narrow, distal edge curved. Tergal disk (3 rd tergite) about three times longer than wide, covered with about 30 conical spines.

Bionomy. The early stages and the foodplant are unknown.

Distribution. South Africa, De Wet and Matjiesfontain, Western Cape Province.

Etymology. The species name is from Greek στενός = “narrow” and πτερόν = “wing”, and refers to aspect of the forewing.
