Type specimen. Holotype: Male , Guinea, Mt. Nimba, ix 2010, coll. ZSM, gen slide no. 4270/Karisch, in ZSM.

Paratype: 1♂, Guinea, Mt. Nimba , ix 2010, coll. ZSM , in ZSM.

Diagnosis. Similar to D. mediolinea Park & Karisch, 2022 (from Ivory Coast), but distinguished by the narrower costal patch, the postmedian fascia being very weak or nearly absent, and the absence of yellowish-white fringes. In D. mediolinea , the costal patch is well-developed, triangular, and fringes with yellowish-white band beyond apex. The hindwing ground colour is darker with a small wedge-shaped costal patch and no yellowish-white basal line (in D. mediolinea , the costal patch extends to half the cell). The male genitalia resemble those of D. curvalis sp. nov. but the valva is shorter.

Description. Male ( Figs 5A, B View FIGURE 5 ). Wingspan 11.5 mm.

Head: Shiny whitish dorsally. Antenna filiform; basal segment slightly broadened apically, dark brown; flagellum pale yellowish brown, annulated with dark-brown rings. Labial palpus arched; second palpomere slightly broadened, yellowish brown medially, shiny pale yellowish laterally; third palpomere as long as the second, greyish brown. Hind tibia yellowish white dorsally, soot brown in proximal half.

Thorax: Soot brown dorsally as tegula. Forewing ground colour soot brown; costa slightly convex around basal 1/3 and beyond 3/4, with a small, wedge-shaped yellowish-white costal patch at about 3/4; antemedian fascia narrow, yellowish white, strongly zigzagged; postmedian fascia weakly presented; termen nearly straight; fringes concolorous with forewing ground colour. Hindwing same as forewing ground colour, with a small, triangular, yellowish-white costal patch beyond 3/4; fringes concolorous with ground colour.

Abdomen ( Fig. 5D View FIGURE 5 ): Soot brown dorsally, yellowish white laterally and ventrally; spinous zones on dorsal surface with rare spines.

Male genitalia ( Figs 5C, C View FIGURE 5 1 View FIGURE 1 ): Uncus slender, bent downward from beyond 2/3, with acute apex. Basal plate of gnathos triangular, with acute caudal apices; median process gently arched dorsally, with sharply pointed apex. Tegumen broad, weakly sclerotized, triangularly incised on anterior margin. Valva broadly expanded at base, deeply concave medially; ventral margin nearly straight, slightly sinuate; cucullus foot-shaped, produced apically, with rounded lower corner; sacculus weakly developed basally. Vinculum narrowly banded, heavily sclerotized. Juxta large, quadrate, slightly concave on caudal margin, with weak vertical ridge; caudal lobes absent.Aedeagus stout, as long as valva, slightly bent basal 1/4 ventrally; cornuti consisting of a bundle of several strong spines near basal 1/4, a large bundle of numerous spines and minute spinules beyond middle, and several short, strong spines apically.

Female unknown.

Distribution. Guinea (Nimba Mts.)
