Type material.
Holotype ♂, [Iran], "S-Iran, Strasse Shiraz-Kazerun, Imam Sade, 1200 m, 3.vi.1969, H.G. Amsel leg." | "gen. slide 47/18, O. Bidzilya" ( SMNK); Paratypes: 3 ♂, 4 ♀, same data as holotype (gen. slide 1/18♂, 77/18♀, O. Bidzilya); 1 ♂, S-Iran, 4-7.vi.1969, Miyan Katal, 1900 m, östl. Kazerun, 51°40 ’öL, 29°30'nB (Amsel) (all SMNK)
Diagnosis.
The new species is defined externally by the forewing narrowed in distal half and less extensive black pattern contrary to the other blackish-white Tricerophora -species. T. brumale sp. n. is more strongly black-irrorated and the forewings are not narrowed in distal half. The apically acute valva with merged sacculus and broad sub-triangular saccus are characteristic for the male genitalia. The female genitalia are distinct by sternum VIII broadly sclerotized laterally in combination with long and broad ductus bursae which is sclerotized in distal half only.
Description.
Adult (Figs 17-18 View Figures 11–20 ): Wingspan 10.0-12.0 mm. Head white with rare black-tipped scales on neck, labial palpus white, segment 2 with black base and rare black scales on outer surface, brush of scales underside, segment 3 acute, white mottled. Scape light brown, flagellum light brown with white belts, pubescent by male on underside. Thorax and tegulae white mixed with black-tipped scales. Forewing white with veins distinctly mottled with black, black streak on mid width from 2/3 length towards apex, cilia white black-tipped. Hindwing and cilia grey.
Male genitalia (Fig. 26 View Figures 25–28 ): Posterolateral processes of tegumen moderately long, pointed; uncus straight; gnathos about 3/4 length of uncus, weakly constricted in middle, apex broadly rounded; tegumen twice as long as broad; valva moderately broad, of even width, haired, far extending beyond the top of uncus, apex elongated and distinctly pointed; sacculus merged with valva; vinculum four times as broad as long, about 1/6 length of valva, posteromedial lobe trapezoidal, medially broadly emarginated, extending to 1/4 length of valva; saccus broad, sub-triangular, apex rounded; phallus swollen on base, slightly broadened distally, cornutus short, broad on base.
Female genitalia (Fig. 37 View Figures 36–38 ): Sternum VIII as long as broad, membranous except for strongly sclerotized areas along lateral margins; ostium indistinct; apophysis anterioris slightly longer than segment VIII; antrum tubular, somewhat broadened in distal 3/4, as long as length of apophysis anterioris; ductus bursae 1.5 times as broad as antrum, with sclerotized patch in distal half along right margin, left margin weakly inflated distally, twice as long as apophysis anterioris, with distinct transition towards egg-shaped corpus bursae; arms of signum of equal length and width, gradually narrowed apically, distinctly serrated.
Etymology.
The specific name is derived from Latin “acutus” - sharp, and “valva” - clasper, referring the apically pointed valva of the new species.
