(Figs 10 A–G)

Type material. Holotype: male, Ghana, Central, Kakum N. P. 150 m, 5°20′54″N 1°23′7″W, 19 xi 2011, D.J.L. Agassiz; gen. slide no. CIS-7196; COI Barcode CBNU103. Paratype: 1♀, same data as holotype; gen. slide no. CIS-7156; wing slide no. CIS-7447; COI Barcode CBNU089, in NHMUK.

Diagnosis. This species is similar to D. hispidula Park, 2018 which was described from Cameroon, by having soot-brown forewing ground color with similar yellowish white bands on the forewing, but it can be distinguished from the latter by having the postmedian band broadly suffused toward costal margin in the forewing; and the male genitalia with pentagonoid basal part of gnathos distally and the aedeagus produced with spatulate apex dorsally.

Description. Male (Figs 10A, B). Wingspan 13.0 mm. Head: Yellowish white, mixed with pale yellowish brown scales centrally. Antenna slightly shorter than forewing; basal segment elongated, black all around; flagellum yellowish white throughout, without annulations, finely ciliate. Second palpomere of labial palpus thickened, arched, dark brown dorsally and on outer surface, yellowish white ventrally; 3 rd palpomere slender, strongly upturned, shorter than 2 nd palpomere, yellowish white, with some dark brown scales beyond 2/3 dorsally. Thorax: Tegula yellowish brown dorsally, with dark fuscous scales anteriorly; thorax yellowish white dorsally. Hind tibia white in basal 1/3 and roughly scaled with dark yellowish brown, strong setae in distal 2/3 on outer surface; tarsi yellowish white. Forewing ground color soot brown; antemedian band yellowish white, with serrate margins; a small crescent, yellowish white marks followed by oblique, yellowish white streak, extended to postmedian band; postmedian band well-developed, oblique, triangularly broadened in anterior 1/4; costa nearly straight, then slightly oblique beyond 3/4; apex acute; termen oblique; fringe with distinct yellowish white basal line, then concolorous with ground color; venation (Fig. 10B) with R 1 arising from about basal 2/3 of discal cell; R 3 stalked with R 4+5 for basal 1/3; R 5 reaching costa; M 2 arising from lower corner of discal cell; M 3 merged to CuA 1; CuA 1 and CuA 2 short-stalked; 1A+2A not forked at base. Hind wing of same color as forewing; postmedian band well-developed, yellowish white; venation with M 2 present; M 3 entirely merged with CuA 1; Cup well-developed, arising near base. Abdomen (Fig. 10F): Spinous zones on dorsal surface sparsely spined; tergite VIII heavily sclerotized, with linear sclerite along anterior margin.

Male genitalia (Figs 10 C–E). Uncus elongate, medially bent downward, not reaching apex of basal plate of gnathos. Basal plate of gnathos pentagonal in distal part; median process large, strongly bent beyond middle, with sharply pointed apex. Tegumen weakly sclerotized, with concave anterior margin. Valva broad basally, narrowed toward cucullus; costa convex near base, then oblique; ventral margin nearly straight; sacculus weakly developed; cucullus with rounded outer margin, densely setose; apex acute. Juxta jar-shaped, with a small, triangular median process on caudal margin; latero-caudal lobes nearly undeveloped; median vertical ridge weakly developed. Aedeagus as long as valva, narrowed toward apex; dorsal surface terminated into a small, sclerotized, rake-shaped protrusion; cornutus forming a large sac with minute spinules.

Female genitalia (Figs 10G). Apophyses anteriores about 1/2 length of apophyses posteriores.Antrum membranous, large, cup-shaped. Ductus bursae narrowed in posterior 1/5, then broadened toward corpus bursae, about 1.7x length of corpus bursae; ductus seminalis arising from nearly end of the broadened part. Corpus bursae large, ovate; signum nearly symmetrical in upper and lower plates, with dense conic spines; median transversal furrow narrow.

Distribution. Ghana (Central).

Etymology. The species name is derived from the name of the country of the type locality.
