Type material. Holotype: male, Uganda, Western, Kibale Nat. Park, Kanyawara 1520 m, 0°33′39″N 30°21′27″E, 22 x 2014, leg. D.J.L. Agassiz; gen. slide no. CIS-7186; COI barcode CBNU102 . Paratype: 2♂, same data as holo- type; gen. slide no. CIS-7012; wing slide no. CIS-7448; COI Barcode CBNU066 & - CBNU017, in NHMUK .

Diagnosis. This species can be easily distinguished from all previously described species of the genus by the purplish dark brown ground color of both wings, with narrow, light orange antemedian band, a small, light orange discal spot, an oblique postmedian line, originating from costal patch, discontinued to inner margin, and with subterminal line in the forewing. The male genitalia can be distinguished from its allies by the cucullus elongated with round apex.

Description. Male ( Figs 9 A–C). Wingspan 14.0 mm. Head: Yellowish brown anteriorly; vertex yellowish brown centrally with yellowish white, erect scales laterally. Antenna slightly shorter than forewing; basal segment elongated, slightly dilated distally, purplish dark brown all around; flagellum yellowish white throughout, without annulations. Second palpomere of labial palpus thickened, arched, yellowish brown in basal half, yellowish white speckled with brownish scales in distal half on outer surface, yellowish white on inner surface; 3 rd palpomere slen- der, strongly upturned, shorter than 2 nd palpomere, yellowish brown on outer surface. Thorax: Tegula yellowish white, with purplish dark brown scales; thorax yellowish white, densely covered with purplish dark brown scales anteriorly and posteriorly. Hind tibia yellowish white in basal half, with yellowish brown, piliform scales above in distal half. Forewing ground color purplish dark brown; with light orange basal streak; antemedian band narrow, light orange, slightly expanded on costa; a small, light orange discal spot present; postmedian line oblique, originating from light-orange costal patch, discontinued to inner margin; subterminal line arising from beyond apex, extended to tornus along termen; costa arched beyond 3/4; apex produced, sharply acute apically; termen oblique; fringe with paler basal line and dark brown median band. Hind wing ground color same as forewing, with broad, yellowish white costal fascia in basal 2/3; postmedian band visible in anterior 1/3; apex sharply produced; fringe concolorous with ground color, with narrow, pale orange basal line and dark brown median band. Abdomen ( Fig. 9G ): purplish dark brown, with light orange transverse bands on dorsal surface of segments III–VI; spinous zones on dorsal surface more or less sparse spines; tergite VIII with crescent sclerite on anterior margin; sternite VIII broadly convex on posterior margin.

Male genitalia ( Figs 9 D–F): Uncus slender, long, gently bent medially, reaching apex of basal plate of gnathos, acute apically. Basal plate of gnathos narrowed in distal half; median process rather slender, strongly bent beyond middle, with sharply pointed apex. Tegumen sclerotized, deeply concave on anterior margin. Valva elongated, slightly narrowed distally; costa with small basal expansion anteriorly, then nearly straight beyond; ventral margin slightly convex before middle; sacculus weak, nearly invisible; cucullus foot-shaped, with round apex; outer margin slightly arched, densely setose. Juxta broad, shield-shaped, broadened distally, with heavily sclerotized median ridge; anterior margin emarginated at middle.Aedeagus stout, slightly shorter than valva, dilated distally, bifurcated apically; dorsal surface terminated with semi-ovate protrusion; vesica without plate.

Female unknown.

Distribution. Uganda.

Etymology. This species name is derived from the Latin, pedis- (= foot), with a Latin suffix, -alis, referring to the foot-shaped cucullus of the male genitalia.
