ETYMOLOGY: The species is named after the French composer Hector Berlioz

(1803-1869).

DIAGNOSIS: Differs from closely related species, C. mozarti and C. frescobaldii , in smaller average size (17-20 mm versus 18-22 mm). In male genitalia this species is more similar to C. mozarti but the pedunculi of the tegumen are narrower, the costa of the valva has a more strongly developed dorsal extension, and the dorsal apical tooth FIGS 20-21

of the valva is smaller. In female genitalia the lamella postvaginalis is apically rounded as opposed to truncated or concave in other species of the complex.

DESCRIPTION (Figs 5-6): Wingspan 17-20 mm. Labial palpi 4 X longer than widest diameter of eye, white on inner side, otherwise golden brown. Maxillary palpi white, golden brown on basal half. Frons slightly produced, rounded, white with brown scales. Antennae serrate in male, simple in female, brown with white costa. Ocelli and chaetosemata present. Head white. Patagium laterally golden brown, medially white. Tegulae brown. Thorax whitish suffused yellow, with brown medial line. Forewings with pointed apex; ground color brown; medial silvery stripe with dorsal tooth at about half the length, largely bordered with dark brown scales and reaching inner line of submarginal area; inner submarginal line brown; submarginal area with scales ivory with brown tip; fringes white with ivory basis. Hindwings, including fringes, white. Legs brown.

MALE GENITALIA (Fig. 17): Uncus subvestigial and membranous. Gnathos broadly bilobed, poorly sclerotized. Tegumen narrow, with pedunculi 1,7 X longer than gnathos. valva short with costal swelling strongly produced upward, cucullus with second tooth short. Phallus slightly longer than whole apparatus. Vesica with 2 small and one medium-sized cornuti.

FEMALE GENITALIA (Fig. 21, 25): Papillae anales simple, without medial fold, but with membranous and speculate dorsal fold. Apophyses posteriores medium sized, with bulge apically. Ostium bursae small and rounded, slightly produced from middle of lamella antevaginalis. Sterigma with lamella antevaginalis moderately bifurcate and lamella postvaginalis lightly sclerotized.
