Trisuloides xizanga Han, Kononenko & Behounek sp. n.
( Figs. 29, 30 View FIGURES 23 – 30 , 54 View FIGURES 54 – 56 , 65 View FIGURES 57 – 66 )
Type material. Holotype: male, China, Prov. Xizang, Hanmi-Motuo, 2100 m. 18–28.viii.2005, Huang, Zhou, Tang, genit.prep. HHL-1768-1(coll. NEFU). Paratype: male with same data as holotype, genit. Prep. HHL-1781- 1. The holotype and paratypes deposited in the collection of NEFU.
Diagnosis. The new species differs from its congeners by its larger size, more elongate shape of forewing, reddish-brown ground color and light pale-greyish suffusion along veins, which is especially expressed in subterminal and terminal fields. It is closest to T. taiwana but externally differs from the latter by the absence of pale whitish suffusion in mid part of wing around reniform and in the subterminal field; in male genitalia it differs by the thinner uncus, shape of valva and shape of harpe, which is large, leaf-like, and serrate along lateral margin.
Description. Adult ( Figs. 29, 30 View FIGURES 23 – 30 ). Wingspan 55–60 mm. Head and thorax covered with brown hair-like scales, tegulae and patagia bordered with whitish; abdomen with crest on segments 1–5 formed by brown erected scales bordered with whitish. Forewing somewhat narrower and elongate comparing with other species. Ground color of forewing reddish brown with whitish irroration; basal line black-brown, diffused; subbasal field with diffused darkbrown area; subbasal line distinct, blackish brown, outlined with whitish inwardly; orbicular distinct, reniforn indistinct, no pale suffusion in reniform area; medial shadow diffused; double submedial fascia peaked on veins, in costal and subtornal area with white marks; subterminal field dark brown, dentate, with whitish irroration; terminal field brown, veins in terminal field suffused with grey; terminal line as row of semicircular streaks, bordered with whitish inwardly; cilia brown between veins, yellowish opposite veins. Hindwing yellow with brown basal patch and wide terminal band. Male genitalia ( Fig. 54 View FIGURES 54 – 56 , 65 View FIGURES 57 – 66 ). Uncus longer and somewhat narrower than in related T. taiwana ; tegument broad, somewhat higher than vinculum; juxta shield-like; valva longer than in taiwana , broader in apical third, narrover apically, with rounded apex; lobes of sacculus smaller than in T. taiwana and deeply cut basally; harpe much larger than in T. taiwana , almost reaching costa, wide, leave-shaped, on short basis, serrate along apical and lateral margings; a heavily setose flap-like costal process (editum) smaller than in T. taiwana . Aedeagus with posterior end protruded ventrally like in T. rotundipennis , carina with few minute spines; vesica with basal and subapical diverticula smaller than in rotundipennis . Female unkbown.
Etymology. The name “ xizanga ” is derived from the type locality, the Autonomous Region Xizang, southwest China.
Distribution and biology. Occurs in southwest China (Autonomous Region Xizang). Two specimens were collected in late August at an elevation of 2100 m.
