(Figs. 9, 33, 33a, 54)  
 Description. Adult (Fig. 9): Wingspan 17.5–20.0 mm. Head whitish yellow. Antenna deep-yellow ringed with deep leaden. Labial palpus grayish-yellow, second segment black at base, third segment with black annulus at base and before apex. Thorax, tegula and forewing grayish-yellow, diffused with leaden scales. Forewing white with black spots on costa at base, 1/6, 1/3 and 3/5, basal one smallest, distal one semicircular and largest, extending posteriad to subcostal vein; black dots at middle of anterior margin, at 2/3 length and end of cell as well as at 3/5 length of fold, the one at end of cell rounded, and largest; a series of black dots ranging from about distal 1/4 of costal margin along termen to tornus; cilia grayish-yellow mixed with leaden. Hindwing gray; cilia gray tinged with yellow. Legs grayish-yellow; fore leg brown, fore tarsus brown and grayish-yellow on ventral surface; mid leg brown and grayish-yellow on outer side.   
Male genitalia (Fig. 33, 33a): Eighth sternum with a strong thorn at middle on posterior margin. Brachia of uncus setose at base, slightly expanded in distal 2/5, narrowly rounded at apex. Valva broad and short, nearly trapezoidal, widened distally; valvella shorter than valva, broad and setose at base, slightly curved downward, convex at 3/5 dorsally, distal 2/5 densely setose, gradually narrowed to roundly pointed apex. Anellus strongly sclerotized, gradually narrowed distally; apex rounded, reaching 4/5 length of tegumen, setose laterally. Phallus membranous at base; cornuti consisting of numerous longitudinal spines distally, forming a large bundle.  
Female genitalia (Fig. 54): Posterior apophysis more than twice as long as anterior apophysis. Sterigma slightly narrowed posteriorly, anterior margin roundly convex, posterior margin slightly concave. Ductus bursae nearly same length as posterior apophysis; ductus seminalis arising from posterior end of corpus bursae. Corpus bursae large, narrow posteriorly, broad anteriorly, same length as posterior apophysis; signa paired, crescented, about 1/3 length of corpus bursae, heavily sclerotized, with numerous toothlike spinules on outer surface.  
 Type material. Holotype ♂, MADAGASCAR: Betroka [23°16' S, 46°05' E], xi/ xii.1953, E. Diehl, BMNH Microlep. slide no. 32345, Zhiwei Zhang (BMNH, London).   
Paratype: 1 ♀, BMNH Microlep. slide no. 32346, Zhiwei Zhang (BMNH, London), other same data as for holotype.  
 Distribution. Madagascar.   
 Diagnosis. This new species can be distinguished from its congeners by the eighth sternum with a strong thorn at middle on posterior margin in male; the signa crescented and slightly curved, with numerous toothlike spinules on outer surface in female.   
 Etymology. The specific epithet is derived from the type locality, Betroka, Madagascar.
