Diagnosis. This species has a pale appearance with a light covering of ochre scales along the veins. The male genitalia are similar to those of C. ensifera   sp. nov., but with evident differences in the shape of the protuberances of the sacculus and the shape of the phallotheca. The female genitalia are similar to those of C. ordinaria Meyrick, 1913   , known only from South Africa. In C. ordinaria   the colliculum is shorter and wider in the proximal part; the ductus bursae is shorter, wider and completely transparent.

Description. Wingspan 10 mm. Head dirty white, suffused with ochre on dorsum. Antenna ochre, slightly ringed dirty white; scape without tuft of scales. Labial palpus whitish on inner side and almost completely brown on outer side; second segment 1.5 times longer than third. Proboscis normal, shorter than labial palpus. Thorax and tegula light ochre. Forewing dirty white suffused with ochre and scattered with sparse brown scales especially in apical area at base of fringe; fringe straw-coloured. Hindwing light grey with concolorous fringe.

Male genitalia ( Figs. 49, 51, 52 View FIGURES 49–52 ): Gnathos knob globular. Tegumen restricted in middle, pedunculus externally slightly dilated. Transtilla thin and curved. Valvula small, oval. Cucullus short, stout, ear-shaped. Sacculus with curved and sharp protuberance in ventral corner and a longer and thin horn-shaped protuberance in dorsal corner. Phallotheca with two thin juxta rods, sclerotized only dorsally, shorter one with a dorsal blunted tooth before apical part, which is thinner. Cornuti absent.

Female genitalia ( Figs. 53, 54 View FIGURES 53–55 ): Papillae anales ovoid. Apophysis posterioris about half as long as anterioris. Sterigma trapezoidal, sclerotized only laterally at base of apophyses, distal edge slightly concave relative to ostium bursae. Colliculum in shape of an elongated calyx, narrower in proximal part. Ductus bursae transparent, except in central part, which is thinner, sclerotized, with a short medial line. Corpus bursae ovoid and elongated without signum.

Abdominal structures ( Fig. 50 View FIGURES 49–52 , 55 View FIGURES 53–55 ): No posterior lateral struts. Transverse strut, slightly curved, thick, and well sclerotized on both sides. Tergal disk about 8 times as long as wide, covered with about 30 spines.

Bionomy. The early stages and the foodplant are unknown.

Distribution. The species is known only from Kenya.

Etymology. The name derives from the geographical area where the specimens were collected.
