A. Prozorov , T. Prozorova et al ., GS 1005 ( CGM / USTTB ) . Paratypes : ♂ , same data as holotype but GS 1010 ( CGM / USTTB ) ; ♂ paratype of S. alucard , Gabon , Ipassa , 8.IV.1973 , leg. G. Bernardi & J. Pierre , GS 2005- 04 ( MNHN ) . Description . Male ( Figs 1–2 ). Antennae, head, thorax and abdomen dark brown. Forewing . Forewing length: 16.5–17.5 mm ; wingspan: 33–34 mm .

Somewhat ovate with almost straight outer margin. Background color dark brown. Dark discal dot pronounced. Fringe dark brown. Genitalia ( Figs 13–14 , 17–18 ). Cucullus narrows in distal half. Lobes of juxta short, widened medially. Saccus distally wide with two rounded apices. Lateral extensions of vesica elongated. Laterodistal dents of the 8 th sternite elongated. Female remains unknown. Diagnosis . Adult males of S. sophia sp. n. have forewings with rounded apex and dark discal dot ( Figs 1–2 ), medially widened lobes of juxta, longer saccus, longer lateral extensions of vesica ( Figs 17–18 ), and longer laterodistal dents of the 8 th sternite ( Figs 13–14 ), while adult males of S. alucard have forewings with pointed apex and pale discal dot ( Figs 5–6 ), gradually narrowing lobes of juxta, shorter saccus, shorter lateral extensions of vesica ( Figs 21–22 ), and shorter laterodistal dents of the 8 th sternite ( Figs 15–16 ). Adult males of S. sophia sp. n. have forewings with rounded apex ( Figs 1–2 ), medially less widened lobes of juxta, and distally wider saccus ( Figs 17–18 ), while adult males of S. sara sp. n. have forewings with pointed apex ( Figs 3–4 ), medially more widened lobes of juxta, and distally narrower saccus ( Figs 21– 22 ). Distribution ( Fig. 24 ). Known from only one location in the Central Congolian lowland forests of western DRC . Biology . Adults were collected in November from an altitude of 350 meters a.s.l. Preimaginal stages unknown. Etymology . The species is named in honor of Sophia A. Prozorova, a beloved daughter of first and third authors of the present article.
