(Figs. 17 A–G)

Type specimen. Holotype: male, Uganda, Kibale Nat. Park, Biol. Field Station, 19–24 xi 2014, LF, leg. W. Mey, gen. slide no. CIS-7045, COI barcode CBNU026, deposited in MfN.

Diagnosis. The new species can be distinguished from its allies by the male genitalia with valva broadly expanded apically, and juxta with a specialized, small, slender, curved caudal process.

Description. Male (Figs. 17A, B). Forewing length 7.5 mm. Head: Dark brown dorsally, with yellowish-white erect scales laterally. Antenna slightly shorter than forewing, with basal segment elongated, yellowish white dorsally, dark brown on anterior and posterior surface; flagellum serrate, with fine cilia ventrally, yellowish white dorsally, dark brown laterally in basal 1/3. Second segment of labial palpus thickened, yellowish brown on outer surface, yellowish white with dark-brown scales covered in upper 1/3 on inner surface; 3 rd segment slender, strongly upturned, as long as 2 nd segment, yellowish brown, speckling with dark-brown scales laterally, yellowish white ventrally, sharply pointed apically.

Thorax: Notum and tegula dark brown. Hind tibia orange white, with rough scales above. Forewing ground col- or yellowish brown, scattered with dark-brown scales; costa slightly arched, with small, crescent, yellowish-white costal patch near 2/3 from base; apex obtuse; termen oblique; fringe dark brown, with narrow, yellowish-white basal line. Hind wing pale brownish grey.

Abdomen: Spinous zones on tergites broadly developed. Male genitalia (Figs. 17 C–G): Uncus bifurcate, with slender latero-caudal processes directed outwardly. Basal plate of gnathos deeply concave medially; median process broad at base, narrower toward apex, curved downward beyond 2/3, sharply pointed apically. Tegumen deeply incised in inverted V-shape on anterior margin medially. Valva broadly expanded in about half of costa; cucullus narrowed with nearly parallel-sided, then broadly dilated in distal part, densely setose. Juxta narrowed distally; median plate at base more or less W-shaped with short, digitate lateral lobes, deeply emarginated on anterior margin medially, with a single, slender, curved process apically. Vinculum narrow, band-like. Aedeagus as long as valva, slightly curved, with blunt apex; cornutus sword-shaped, heavily sclerotized, located in distal 1/3.

Female unknown.
