Diagnosis. A species with forewing sandy ochreous, more brownish in the apical region, with lighter streaks.The genitalia do not connect it to any other Afrotropical species, but resemble those of C. longiductella Baldizzone, 1989, a species attributed to Toll’s 9th group, known from Iran, Yemen and Pakistan, of which the habitus is different: it is smaller, and its forewings are uniformly light brown. The male genitalia are rather identical, but stand out by the shape of the sacculus and by the long line of cornuti. In the female genitalia the differences are more obvious, because of the shape of the sterigma with two characteristic symmetrical folds, and the spiculate part of the ductus, which is shorter and wider in longiductella.
Description. The original description of the adult as given by Meyrick is correct: “♂ ♀ 11 mm. Head shining whitish. Palpi whitish, second joint slightly tufted at apex beneath. Antennae whitish, basal joint with rough projecting scales anteriorly. Thorax shining whitish, shoulders sometimes infuscated. Abdomen pale greyish, anal tuft ochreous-whitish. Forewings elongate-lanceolate; rather light ochreous-fuscous or greyish-ochreous, more or less suffused with darker irroration towards apex; costa slenderly white from base to about 2/3; a very fine indistinct whitish line along fold, and three or four feebly marked similar parallel lines above and below it, dorsal area suffused with white towards base; cilia ochreous-grey-whitish, on costa white except towards apex. Hindwings light grey, cilia ochreous-whitish.”(Meyrick 1921: 120)
Male genitalia (Figs. 76–79): Gnathos knob globular, small. Tegumen stretched. Pedunculus small, slightly rounded. Transtilla slender, straight. Valvula wide, little pronounced, rounded, with upper margin more or less pronounced and rounded, on which occurs a large curved bristle. Cucullus long, slender, apically rounded. Sacculus narrow, ventral margin curved, tapering towards an acute dorso-caudal process. Phallotheca broad, transparent, tapering towards a blunt tip. Cornuti a long curved string of needle-like spines, accompanied by a thin sclerotized lamina.
Female genitalia (Figs. 80, 81): Papillae anales stretched, narrow. Apophysis posterioris slightly less than twice length of anterioris. Sterigma subtrapezoid; distal margin rounded, medially excavated towards ostium bursae. Ostium bursae V-shaped. Colliculum chaliced, half length of sterigma. First section of ductus bursae transparent with strong medial line; second section, about 18 times longer than sterigma, a strongly chitinized band enveloped in a sleeve speckled with tiny spikes, continuing into several wide convolutions; third segment transparent, merging into a sack-like bursa, provided with a large leaf-like signum.
Abdominal apodemes (Fig. 82): No posterior lateral struts. Transverse strut with convex slender margins. Tergal disk three times longer than wide, covered with about 36 tiny spikes.
Bionomy. The foodplant and the early stages are not known
Distribution. Widespread: from Namibia and South Africa to Tanzania and Kenya.
