Frons (Fig. 2B View Figure 2 ) claviform, 2.58 times as long as wide. Pronotum (Figs 1A View Figure 1 , 2A View Figure 2 ) as long as vertex. Mesonotum 1.40 times longer than pronotum and vertex combined, lateral carinae curved outwards. Forewing (Figs 1B View Figure 1 , 2C View Figure 2 ) 2.28 times longer than wide, with 12 apical cells and six subapical cells; RP 3 branches, MP with five terminals: MP11, MP12, MP2, MP3, and MP4, fork MP1+MP2 basad of fork MP3+MP4. Hind tibia with three lateral spines; chaetotaxy of hind tarsi 6/7.
Male genitalia. Pygofer (Fig. 3A, C View Figure 3 ) symmetrical. Medioventral process rounded protruding in ventral view. Anal segment (Fig. 3A, D View Figure 3 ) asymmetrical, apical margin expanded downwards in lateral view; 2.28 times longer than wide in dorsal view; anal style strap-shaped, not beyond anal segment. Gonostyli (Fig. 3B, C View Figure 3 ) symmetrical ventrally; in inner lateral view, base slender, apex enlarged. Aedeagus (Fig. 3E-H View Figure 3 ) with five processes. In left side view, basal ventral margin of periandrium protruding; in right side view, base of periandrium with a U-shaped spinose process, directed cephalad; in ventral view, near base of periandrium with a long spinose process, apex curved upwards, forming a hooked process, directed cephalad. Endosoma somewhat long, apex with a hooked spinose process.
Distribution.
China (Xizang) (Fig. 12 View Figure 12 ).
Etymology.
The specific name is derived from the Latin adjective flagellihamus, referring to the 1-hooked spinose process arising from the apex of the endosoma.
Remarks.
This species can be distinguished from the other species of the genus by the following characters: basal right side of periandrium with a U-shaped spinose process; basal ventral margin of periandrium with a long spinose process, apex curved upwards, forming a hooked process; apex of endosoma with a hooked spinose process.
