Park, Biol. Field Sta- tion, 19–24 xi 2014, LF leg. W. Mey; gen slide no. CIS-7007 ; 2♂, same data as holotype; gen. slide no. CIS-7467; wing slide no. 7446; gen. slide no. CIS-7058; COI Barcode CBNU055 & CBNU064, in MfN .

Diagnosis. Due to similar forewing pattern, this species resembles the preceding new species, D. ghanaensis sp. nov., but it can be distinguished by the forewing postmedian band which is less broadened anteriorly than in D. ghanaensis sp. nov., and the hind wing with differently developed CuP as noted in the following description. The male genitalia can be distinguished from the latter by the basal plate of the gnathos which is truncated apically, whereas in the latter it is pentagonal; valva more elongate, juxta with nearly straight caudal margin.

Description. Male ( Figs 11 A–E). Wingspan 15.0 mm. Head: Yellowish white dorsally. Antenna slightly shorter than forewing; basal segment elongated, blackish all around; flagellum yellowish white throughout, without annulations, finely ciliate. Second palpomere of labial palpus thickened, arched, yellowish white, speckled with brown scales on outer surface, dark brown dorsally, yellowish white apically; 3 rd palpomere slender, strongly upturned, shorter than 2 nd palpomere, yellowish white, speckled with some dark brown scales. Thorax: Tegula yellowish white, speckled with dark fuscous scales anteriorly; thorax yellowish white dorsally. Hind tibia ( Fig. 11E ) white in basal 1/3 and roughly scaled with dark yellowish-brown scales in distal 2/3 all around. Forewing ground color yellowish brown; antemedian band yellowish white, nearly parallel-sided; a small crescent, yellowish white mark connects postmedian band by an oblique band; postmedian band oblique, slightly broadened at costa; costa slightly oblique beyond 3/4; apex more or less acute; termen oblique, slightly sinuate; fringe with narrow yellowish white basal line and yellowish brown median line, white distally; venation ( Fig. 11D ) similar to that of D. ghanaensis sp. nov. Hind wing ground color paler than forewing; postmedian band well-developed, yellowish white, strongly angled on vein M 2; apex acute; venation with M 2 well-developed; M 3 entirely merged with CuA 1; Cup uniquely developed, arising near base, arched in cell and crossing lower margin of cell at about middle. Abdomen ( Fig. 11H ): Spinous zones on dorsal surface broad, densely spiny; tergite VIII heavily sclerotized with crescent sclerite along anterior margin; sternite VIII concave on caudal margin.

Male genitalia ( Figs 11F, G ): Uncus rather short, reaching apex of basal plate of gnathos. Basal plate of gnathos truncated on caudal margin; median process large, strongly bent beyond middle, with sharply pointed apex. Tegumen weakly sclerotized, with concave anterior margin. Valva elongate, slightly narrowed toward cucullus; costa convex near base, then oblique; ventral margin gently concave; sacculus weakly developed, nearly invisible; cucullus more or less elongated, with slightly convex outer margin, densely setose; apex not sharply pointed. Juxta jar-shaped, with nearly straight caudal margin, lacking latero-caudal lobes; median vertical ridge not developed. Aedeagus as long as valva, narrowed toward apex, bent before middle, dorsal surface slightly produced, with Sshaped cornutus distally.

Female unknown.

Distribution. Uganda (Kibale Forest).

Etymology. This species name is derived from the Latin, crinis (= hair) and frutex (= tuft, bush), with a Latin suffix, -alis, referring to the rough piliform scale tuft of the hind tibia.
