Description.

Whole body orange-yellow (Figs 16–19 View Figures 16–21 ). Anterior margin of head curved, posterior margin concave, ocelli brown at junction of head and face, eyes light brown, and crown suture conspicuous, reaching to middle of crown. Pronotum with anterior margin arcuate, anterior domain with a transverse dark depression, middle and posterior domains orange, elevated, and intershield grooves brown, not reaching both margins (Figs 16 View Figures 16–21 , 18 View Figures 16–21 ). Face broad, frontclyeal area elevated in lateral view (Figs 17 View Figures 16–21 , 19 View Figures 16–21 ). Forewing RP and MP’ veins heal at base, m-cells wider than and longer than c cells and r cells, 3 rd apical triangular, 2 nd apical lateral veins subparallel (Fig. 20 View Figures 16–21 ). Hindwing CuA veins unbranched (Fig. 21 View Figures 16–21 ).

Male abdominal apodemes extending to 4 th abdominal segment (Fig. 22 View Figures 22–31 ). Pygofer side lateral view basally broad, apex membranous, dorsal margin abruptly narrowed near middle, resulting in large difference in width between terminal and basal pygofer side lateral view, and pygofer appendage long, distinctly exceeding apex of pygofer, apex split (Figs 23 View Figures 22–31 , 24 View Figures 22–31 , 25 View Figures 22–31 , 31 View Figures 22–31 ). Anal process absent (Fig. 26 View Figures 22–31 ). Subgenital plate long, base slightly broad, subequal in width in terminal half, with 8 individual macrosetae, 39 long, fine setae (Fig. 30 View Figures 22–31 ). Paramere long and narrow, hooked and curved in terminal half, with fine setae subterminally (Figs 28 View Figures 22–31 , 29 View Figures 22–31 ). Aedeagus curved in lateral view, with a pair of lateral processes at base of shaft, which are slightly shorter and narrower than shaft, while apex of paramere curved towards shaft in ventral view (Figs 27 View Figures 22–31 , 28 View Figures 22–31 ). Connective base broad, terminal margin deeply concave (Figs 27 View Figures 22–31 , 28 View Figures 22–31 ).

Material examined.

Holotype: • 1 ♂, Menghai , Xishuangbanna, Yunnan, 2013 - July- 14, coll. Ji-Chun Xing . Paratypes: • 1 ♂, 4 ♀, same collecting information as holotype .

Etymology.

The new species is named after the pair of dark-coloured striped depressions on both margins of the pronotum in specimens examined.

Measurement.

Length of males 3.9–4.0 mm, females 4.1–4.5 mm.

Remarks.

The new species is similar to V. pleuroprominens Zhang & Qin, 2004 in having a well-developed preatrium, slightly shorter than the shaft, and symmetrical lateral processes of the shaft (Fig. 28 View Figures 22–31 ). The latter species is different from the former in that: (1) the apex of the two lateral processes at the base of the shaft deviates from the shaft; (2) the apex of the pygofer of the abdominal processes is unbranched ( Zhang & Qin, 2004 a).
