CIS-7068, COI barcode CBNU034, deposited in MfN .

Diagnosis. This new species can be distinguished from its allies by the male genitalia, especially the nearly quadrate juxta with rounded caudal margin and small, triangular caudal processes.

Description. Male ( Figs. 6A, B ). Forewing length 7.5 mm. Head: Vertex dark purplish brown dorsally, with short, orange-white, erect scales laterally. Antenna shorter than forewing; basal segment elongated, orange white, with dark-brown lines anteriorly and posteriorly; flagellum serrate, with fine cilia ventrally, orange white with darkbrown annulations in basal 1/3. Second segment of labial palpus thickened, saber-shaped, yellowish brown on outer surface, dark brown dorsally; 3 rd segment strongly upturned, as long as 2 nd segment, dark brown ventrally, acute apically ( Fig. 6B ).

Thorax: Notum and tegula dark brown. Forewing ground color dark purplish brown uniformly; antemedian fascia broad, blackish; postmedian fascia weakly developed; costa slightly arched in basal 1/3, lacking costal patch; apex obtuse; fringe concolorous with ground color, with a narrow, orange-white basal line. Hind wing dark brown, with creamy-white streak from base to 3/5 of costa, and with a hair-scale tuft at base; apex acute, fringe with a narrow, orange-white basal line.

Abdomen ( Fig. 6G ): Spinous zones on tergites broad, nearly quadrate, with a pair of long, hair-pencils arising from between segments VII and VIII, about twice the length of segment VII; sternite VIII short, triangularly extended posteriorly, with slender latero-caudal lobes directed outwardly, slightly concave on caudal margin; tergite VIII heavily sclerotized, V-shaped. Male genitalia ( Figs. 6 C–F): Uncus slightly broadened distally, about 1/2 the width of basal plate of gnathos, with slightly convex caudal margin. Basal plate of gnathos with rounded caudal margin; median process broad basally, strongly curved downward beyond 2/3, sharply pointed apically. Tegumen weakly sclerotized, deeply incised in Y-shape on posterior margin medially, with V-shaped anterior margin. Valva with subtriangular protrusion near base on costa, then abruptly oblique; cucullus elongated, nearly parallel-sided, densely setose, upturned, with round apex, gently arched on ventral margin. Juxta large, more or less ovate, with small triangular lateral lobes, with semiovate protrusion on anterior margin medially. Vinculum band-liked, narrow. Aedeagus shorter than valva, about 3/5 the length of valva, with apex slanted, pointed dorsally; cornutus with a bundle of variable length of spines.

Female unknown.

Distribution. Uganda (Kabarole Distr.).

Etymology. The specific name is derived from the type locality, Kibale National Park, Uganda.
