(Figs. 12 A–G)

Type specimen. Holotype: male, Uganda, Mpigi, Mpanga Forest, 25–30 xi 2014, LF, leg. W. Mey; gen. slide no. CIS-7048, wing slide no. CIS-7054, COI barcode CBNU008, deposited in MfN.

Diagnosis. This species is one of the smallest species of the genus, with forewing length of 6.5 mm. The male genitalia can be distinguished from those of all the preceding species by the cucullus narrowed toward apex and the aedeagus with a large, heavily sclerotized, sword-shaped cornutus.

Description. Male (Figs. 12 A–C). Forewing length 6.5 mm. Head: Vertex covered with dark-brown scales, with orange-white, erect scales laterally. Antenna shorter than forewing; basal segment elongated, slightly dilated distally, orange white; flagellum serrate with fine cilia ventrally, often with dark-brown annulations (Fig. 4B). Second segment of labial palpus thickened, saber-shaped, yellowish brown, speckled with irregularly scattered, darkbrown scales; 3 rd segment as long as 2 nd segment, brown, acute apically.

Thorax: Notum and tegula dark brown. Forewing ground color dark brown uniformly; antemedian fascia large, usually well developed, with black scales; postmedian fascia large, rectangular, black; costa slightly arched in basal 1/3 and beyond 2/3, with a small, crescent, yellowish costal patch beyond 3/4; apex obtuse; termen slightly oblique; fringe concolorous with ground color, with narrow, orange-white basal line; venation (Fig. 4C) with R 1 strongly bent outwardly near basal 1/3, R 3 and R 4 stalked for basal 2/5, R 4 reaching before apex; R 5 absent; M 1 close to R 3+4 at base; M 2 arising from lower corner of cell; M 3 parallel to M 2; M 3, CuA 1 and CuA 2 on a common stalk, 1A+2A shortly forked at base. Hind wing pale yellowish brown, with a bundle of hair-scale tuft at base.

Abdomen (Fig. 12G): Spinous zones on tergites elongated longitudinally; tergite VIII heavily sclerotized, Yshaped, with a few spines. Male genitalia (Figs. 12 D–F): Uncus broadened distally, as wide as basal plate of gnathos, nearly truncate caudal margin. Basal plate of gnathos rounded on caudal margin; median process strongly curved downward beyond 2/3, with acute apex. Tegumen weakly sclerotized, with inverted V-shaped incision anteriorly. Valva elongated, slightly expanded anteriorly in basal 1/4 of costa; cucullus elongated, densely setose, upturned, narrowed toward apex from middle, arched before middle on ventral margin. Juxta lacerated, indiscernible. Vinculum band-like, with nearly flat margin anteriorly. Aedeagus about 4/5 the length of valva, nearly straight, but with wavy marginal line due to variable width; cornuti consisting of a large, heavily sclerotized, dagger-like plate with hooked tip distally, and a row of short bristles medially.

Female unknown.

Distribution. Uganda (Mpigi Distr.).

Etymology. This species name is derived from Latin umbra (= shade), with Latin adjectival suffix atilis, referring the fuscous patch on forewing.
