Type specimens. Holotype: female, Côte d’Ivoire, Gouédié , 25 km NW Man, Plantagen in Regenwaldfragmenten, 7°32′n. Br. 7°45′ w. L., ca. 620 mNN, 18 viii 1997 LF (125 W HQL), leg. T. Karisch, gen. slide no. GU-3886/ Karisch, in SDEI . Paratypes: 1♀, same data as the holotype, in MNVD ; 1♀, same locality as the holotype, 20 viii 1997, in SDEI .

Diagnosis. This new species is related to D. vulcaniella Park & Karisch, 2021 , which was described from Bioko, by having the forewing with orange ground color. These two species are only known species with orange ground color of the forewing. It can be distinguished from the latter by the forewing pattern lacking yellowish white antemedian and postmedian bands, and the hind wing with grayish shade broadly occupied. The female genitalia can easily be distinguished by having an extremely broad ductus bursae.

Description. Female ( Figs. 12A, A 2 ). Wingspan 14.0 mm. Head: Pale orange dorsally; frons yellowish. Antenna slightly longer than forewing; scape elongated, pale orange; flagellum pale orange, paler beyond 2/3, without distinct annulations, slightly serrate, finely ciliate. Second palpomere of labial palpus long, slightly thickened, arched, pale orange on outer surface; 3 rd palpomere slender, strongly upturned, about 2/3 the length 2 nd palpomere. Thorax: Pale orange, tegula same color. Hind tibia pale orange, with a short, blackish scale-tuft medially and at distal end; spurs pale yellowish. Forewing ground color pale orange; antemedian fascia broad pale grayish brown; postmedian fascia broadly suffused with pale brownish scales; a small dark-brown dot near middle of cell; costa arched in basal 1/3; apex slightly produced; termen oblique; fringe pale orange. Hind wing yellowish orange, with grayish shade broadly occupied in the middle; apex produced; fringe yellowish orange.

Female genitalia ( Fig. 12B ): Abdominal sternite VIII slightly emarginated medially. Apophyses anteriores less than 1/2 the length of apophyses posteriores. Ostium bursae concave. Antrum bowl-shaped, sclerotized, short. Ductus bursae extremely broad, necked between antrum and ductus bursae, without conjunction with corpus bursae. Signum in corpus bursae rather small, upper and lower plates asymmetrical, upper one larger.

Male unknown.

Distribution. Ivory Coast (Montagne District).

Etymology. The specific name is derived from the Latin, - flavus (= yellow) and - aureus (= golden), referring to the yellowish ground color of the forewing.
