Material examined.
Holotype: apterous ♂, China, Hubei Province, Wufeng County, Houhe National Nature Reserve : 30.0869°N, 110.5520°E; 1085 m a.s.l.; 2015-VIII-8; Zhen Ye leg. (NKUM) GoogleMaps . Paratypes: 1 apterous ♀ 1 macropterous ♀, same data as holotype (NKUM) GoogleMaps .
Diagnosis.
Body large, mainly brown. Connexiva straight in dorsal view, with dark yellow strips in male and brighter strips in female (Figs 1a-c View Figure 1 , 3a, b View Figure 3 ), connexival spines sharp and dorsocaudally directed in female (Fig. 3a, b View Figure 3 ); abdominal segment VIII of male stout and ventrally concaved (Fig. 6a, b View Figure 6 ); proctiger of male with triangular dilations on each side and broadly rounded hind margin (Fig. 7a View Figure 7 ).
Comparative notes.
Velia bui sp. nov. and V. longiconnexiva are similar in the coloration and size of the body. However, the female of V. bui sp. nov. can be easily distinguished from that of V. longiconnexiva by its nearly straight connexiva and relatively slender, straight, sharp, slightly directed dorsad connexival spines (Fig. 3a, b View Figure 3 vs. 3c, d). The male of the new species can be distinguished from that of V. longiconnexiva by its relatively stout segment VIII in lateral view and slightly emarginated dorsal hind margin (Fig. 6a, b View Figure 6 vs. 6c, d), the triangular lateral dilations and the broadly rounded hind margin of proctiger (Fig. 7a View Figure 7 vs. 7b).
