Trisuloides prosericea Han, Kononenko & Behounek , sp. n.

( Figs. 23 , 50 , 61 )

Type material. Holotype: male, [ China, Prov. Guangdong, Nanling Mountains], 22.ix.2001, genit. prep. HHL- 1053-1 (coll. SCAU). The holotype is deposited in the collection of SCAU.

Diagnosis. In the shape, color and pattern of forewing this new species is similar to T. sericea ; it differs from the latter by a redder tint and prominent antemedial fascia, filled between borderlines with white. In the male genitalia it differs from T. sericea by the short, abrupt harpe, bearing two basal teeth.

Description. Adult ( Fig. 23 ). Wingspan 55 mm. Head and thorax covered with reddish-brown hair-like scales, tegulae and patagia bordered with whitish. Forewing reddish-brown; basal line indistinct, diffused; submedial line distinct, waved; medial field darker, reddish-brown with diffused medial shadow; orbicular distinct, reniform indistinct, marked outward by black streak; area around reniform paler than ground color; double postmedial fascia peaked on veins, filled between lines with whitish, with clear white, bordered with black subtornal mark; subterminal field blackish-brown, with pale grayish irroration; subterminal line dentate; terminal field reddish brown, with whitish patch in tornal angle; terminal line as a row of dark brown semilunar streaks; cilia brown. Hindwing yellow, with brownish basal part and wide terminal band. Male genitalia ( Figs. 50 , 61 ). Uncus, tegumen, vinculum and juxta similar to those of T. sericea ; valva somewhat wider than in T. sericea and more acute apically; harpe digitate, more massive and shorter than in T. sericea , apically abrupted, directed dorso-transversaly, serrate, with small teeth along apical and dorsal margins and with large bidentate basal projection. Aedeagus rather slender; protruding ventrally, with heavily sclerotized band on carina; vesica somewhat smaller than in T. sericea . Female unknown.

Etymology. The name “ prosericea ” refers to the close relationship of the new species with T. sericea .

Distribution and biology. The species is known only from the type locality, Nanling Mts. in Prov. Guandong, South East China. The single specimen was collected in September in montane mixed and broad-leaved forest at an elevation of ca. 1400 m.
