Tricerophora brumale sp. n.

Type material.

Holotype ♂, "Namibia/Namib, Damaralan, Xaragu Camp, 561 m, 7.viii.2007, GEO-WG84, 14°20'042"E/-20°24'441"S, leg. Dr. C. Wieser, Kärtner Landesmusem" |"gen. slide 106/12, O. Bidzilya" (KLM). Paratypes: 1 ♀, same data as holotype (gen. slide 63/18, O. Bidzilya) (KLM)

Diagnosis.

The new species is defined externally by cream-white forewing gradually mottled with black and brown but without distinct black markings and patterns. T. nigrinervis sp. n. differs in the snow-white head without brown scales, more prominent black marking along veins and white area along dorsal margin of the forewing. T. acutivalva differs in the less black-irrorated and narrowed after half length of the forewing. The long and broad saccus, triangular gnathos, comparatively broad valva and triangular cornutus separate T. wieseri sp. n. from the rest of Tricerophora -species. A short antrum in combination with a long ductus bursae, pear-shaped corpus bursae and signum with broad weakly serrated arms are characteristic for the female genitalia.

Description.

Adult (Figs 13-14 View Figures 11–20 ): Wingspan 10.8-11.2 mm. Head, thorax and tegulae covered with white black-tipped scales, frons white, the female paratype with a head completely white. Labial palpus up-curved, far protruding over the head, segment 2 white with black-tipped scales, nearly white in middle with brush beneath, segment 3 narrow, pointed, white with a few black scales mainly in middle. Scape black, antennal segments white with black rings, male flagellum covered beneath with numerous short hairs (ciliated). Forewing cream-white, densely mixed with black, 2-3 diffuse black patches near the base and in cell, cilia white, black-tipped. Hindwing light grey.

Male genitalia (Fig. 25 View Figures 25–28 ): Posterolateral processes of tegumen short, pointed; uncus long, straight; gnathos slightly shorter than uncus, sub-triangular, broadened from base towards apex; tegumen two times long as broad; valva moderately broad, curved inwards in distal 1/4, haired, slightly extending beyond the top of uncus, apex pointed; sacculus about 1/3 length of valva, straight, apex rounded; vinculum tree times as broad as long and about 1/4 length of valva, posteromedial lobe triangular, extending to about 1/3 length of valva; saccus moderately broad, weakly constricted before apex; phallus weakly swollen on base, cornutus short, triangular.

Female genitalia (Fig. 36 View Figures 36–38 ): Sternum VIII slightly longer than broad, membranous; ostium indistinct; apophysis anterioris about as long as a length of segment VIII; antrum tubular, 1/3 length of apophysis anterioris; ductus bursae entirely sclerotized, of even width, as long as apophysis anterioris, with distinct transition towards pear-shaped corpus bursae; signum with broad, weakly serrated arms, the anterior one slightly longer and broader than the posterior one.

Etymology.

The specific name is derived from Latin " brumalis " -, winter-like, and alludes to the winter activity of the adult.
