( Figs. 4 View FIGURES 1–5 , 19–21 View FIGURES 19–21 )

Holotype ♂ ( GP Bldz 16920) “ ANGOLA (35) | 12 mls. SW Luimbale | c. 5500 ft. | 20–21.iii.1972 ”; Southern African Exp. [edition] | B. M. 1972 – 1”; “ NHMUK 010897635 View Materials [QR code]”, in coll. NHMUK.

Diagnosis. Small species of overall light ochreous appearance, forewing rayed by thin white streaks. Based on the structure of the male genitalia, the species is similar to C. orthocherasella Baldizzone, 2019 known only from South Africa. The main differences are as follows: in C. angolana , sp. nov. the transtilla is much wider and stronger, in the sacculus the protuberance in the ventral angle is longer and sharper, the protuberance in the dorsal angle is longer, thinner and curved, the phallotheca is shorter and stronger without protruding apical teeth.

Description. Wingspan 11 mm. Head white, beige suffused on dorsum and frons. Antenna: scape beige without erect scales, flagellum ringed white and beige. Labial palpus brown, white on upper side; second segment about 2.5 times as long as third. Proboscis of normal shape. Thorax white, beige tinged medially. Tegula white. Forewing light ochre, scattered with a few brown scales more concentrated in apical part at end of veins, rayed by white stripes: along costa, from base up to half, along anal fold a large irregularly shaped stripe, along dorsum a slender stripe; costal fringes beige, darker to apex, dorsal fringes beige. Hindwing light brownish grey, fringes beige. Abdomen white.

Abdominal structures ( Fig. 21 View FIGURES 19–21 ): No posterior lateral struts, transverse strut with proximal edge thin, slightly curved, distal edge much thicker, slightly thinner in middle. Tergal disks (3rd tergite) about 8 times longer than wide, covered with about 30 conical spines.

Male genitalia ( Figs. 19–20 View FIGURES 19–21 ): Gnathos knob globular. Tegumen narrow in middle, pedunculus long, widely expanded and curved on outer edge. Transtilla ribbon-like in basal part, irregularly dorsally dilated in distal part. Valvula bristling with robust setae, very sclerotized in dorsal part, less sclerotized ventrally. Cucullus stout and stocky, slightly narrower at base, ear-shaped. Sacculus with very inclined ventral edge, robust slightly curved and very sharp protuberance in ventral angle, concave lateral edge, large protuberance in shape of a thin horn in dorsal corner, rounded at apex reaching upper edge of cucullus. Phallotheca with two juxta rods sclerotized only in dorsal part: short rod ends thin and pointed at apex, long rod with very small dorsal tooth before apex, which is sharp and very sclerotized. Vesica probably lost during dissection.

Female genitalia: Unknown.

Bionomy. The early stages and the foodplant are unknown.

Distribution. Angola.

Etymology. The name is derived from Angola.
