Cosmetra fibigeri , new species

( Figs. 4 , 14 )

Type material. Holotype, ♂, UGANDA: Rakai Distr.: Sango Bay, Malamigambo Forest, 1140 m, 0 0o 55.796’S, 31o 37.287’E, 1-2.xi.2007, L. Aarvik & M. Fibiger, genitalia slide NHMO 2719 (NHMO).

Diagnosis. Cosmetra fibigeri has a forewing pattern similar to that of C. larseni and C. tumulata . It differs from these two species by its narrower tegumen and smaller socii in the male genitalia.

Description. Male ( Fig. 4 ). Head: Light ochreous, rough scaled. Antenna light ochreous. Labial palpus ca. 1.5 times diameter of eye, light ochreous, lightly sprinkled with brown, brown spot at end of second segment. Thorax: Light ochreous, brown in middle. Fore- and mid-leg grey, with light rings, hind-leg cream, tarsi ringed with light grey. Wingspan 11.5 mm. Forewing upperside light ochreous, dotted with dark brown; costal strigulae marked by dark brown oblique streaks, brown and grey suffusion form a dorso-basal blotch and a smaller rounded tornal blotch. Hindwing light greyish brown, veins with dark suffusion. Abdomen: Light ochreous. Genitalia ( Fig. 14 ) with tegumen narrow; uncus consisting of a single pointed process; socii short, curved; sacculus of valva from one third tapering towards cucullus; outer edge of cucullus rounded, convex, with numerous strong spines along lower half of ventral margin.

Female. Unknown.

Distribution. Uganda.

Biology. The food plant is unknown.

Etymology. This species is named in memory of Michael Fibiger (1945-2011), a close friend who participated in the field work in Uganda, and who contributed tremendously to lepidopteran taxonomy.
