Type specimens. Holotype: female, Côte d’Ivoire, Mt. Tonkoui [Tonkpi], 10 km WNW Man (Südosthang), Sekundärregenwald, 7°28′ n. Br. 7°38′ w. L. ca. 980 mNN, 25 viii 1997 LF (125W HQL), leg. T. Karisch, gen. slide no. GU-3803/Karisch, in SDEI . Paratype: 1♀, with the same data as the holotype, in MNVD .

Diagnosis. This species can be distinguished from its allies by having more elongated forewing with a small wedge-shaped costal patch and the oblique termen, and the antenna white beyond 2/3. The female genitalia have a large, unique, quadrate signum, distinguishing from any previously known species of the genus.

Description. Female ( Figs. 5A, A 2 ). Wingspan 16–16.5 mm

Head: Dark brown with yellowish orange erect scales laterally. Antenna slightly shorter than forewing; scape elongated, slightly broadened distally; flagellum yellowish orange, with dark-brown annulations, serrated towards tip, with fine cilia. Second palpomere of labial palpus thickened, arched, fuscous on outer surface, whitish dusted on inner surface; 3 rd palpomere slender, strongly upturned, grayish brown, a bit longer than 2 nd palpomere.

Thorax: Dark brown. Hind tibia dark brown with yellowish band just beyond mid spurs and apex; spurs grayish brown. Forewing: ground color dark grayish brown, antemedian fascia well-developed, irregularly shaped, black; postmedian fascia not well defined; costa arched in basal 1/3, with a small, yellowish white costal patch beyond 3/4; apex obtuse; termen oblique; fringe dark gray brown, with a narrow, yellowish white basal line. Hind wing evenly grayish brown; apex obtuse; fringe concolorous, with a fine yellowish-white basal line.

Abdomen. Dark grayish brown dorsally. Spinous zones with strong spines.

Female genitalia ( Fig. 5B ): Abdominal sternite VIII deeply emarginated into U-shape medially. Ostium bursae broadly concave. Antrum tub-shaped, membranous, about 1/3 the length of ductus bursae. Ductus bursae extremely broadened as wide as corpus bursae, with no distinct conjunction between corpus bursae, with numerous strong conic spines scattered; ductus seminalis broad, arising from half, about half the width of ductus bursae. Corpus bursae ovate; signum unique, quadrate, with serrated margins anteriorly and posteriorly.

Male unknown.
