description: <i>Leucophenga setipalpis</i> Duda, 1923 (Figs. 2C, 5G–I, 9D, 9E, 13E, 13F, 19) <i>Leucophenga setpalpis</i> Duda, 1923: 31, 1924: 189; Lin &amp; Wheeler, 1972: 251. <b>Diagnosis.</b> This species is most similar to <i>L</i>. <i>zebrina</i> <b>sp. nov.</b> in having the mesonotum mostly brownish yellow (Figs. 5H, 8Q), the pleura with a brown, longitudinal stripe above (Figs. 5I, 8R), the wing slightly brownish along the tip of R 2+3 and dm-cu crossvein (Figs. 2C, 4F), and the shape and pubescence of epandrium, cercus, and surstylus (Figs. 19A, 37A), but can be distinguished from the latter by the colour patterns of abdominal tergites (Fig. 9D, E); paramere anteroventrally with a projection (Fig. 19C); aedeagus basolaterally with a small process, laterally with a long process at same its height; the long process bearing 2 sensilla at tip (Fig. 19D); see below for that species. The specimens employed here are somewhat different from Duda’s (1923) descriptions of the only female holotype from Taiwan, China in the wing slightly brownish along the tip of R 2+3 and dm-cu crossvein (Fig. 2C), and the colour patterns of abdominal tergites (Fig. 9D, E). However, this is a “normal” species with numerous specimens. Moreover, some of these specimens were collected near the type locality. Therefore, all of the specimens were identified as <i>L</i>. <i>setipalpis</i> to avoid further confusion. <b>Description.</b> Ocellar triangle dark brown, with ca. 1 or 2 seta(e) above ocellar setae. Frons brownish (Fig. 5G). Pedicel brownish yellow; first flagellomere yellow (Fig. 5G). Clypeus brownish yellow medially and brownish laterally. Palpus brownish (Fig. 5G). Postpronotal lobe yellow (Fig. 5I). Acrostichal setulae in ca. 12–14 irregular rows (Fig. 5H). Scutellum brownish yellow to brownish, brown to dark brown laterally, yellow at tip (Fig. 5H). Pleura with a brown, longitudinal stripe above (Fig. 5H). Katepisternum and mesopleuron mostly yellowish to yellow (Fig. 5I). Wing (Fig. 2C): Costal vein between R and R 4+5 distally with ca. 5 or 6 peg-like spinules on ventral surface; R 4+5 and M 1 nearly parallel distally; halter mostly yellowish, with a brownish yellow patch at knob (Fig. 5H). Abdominal tergites black, 2nd tergite yellow medially and laterally, 3rd tergite not shortened in males (Fig. 9D, E), yellow anteriorly, sometimes also yellow laterally, 4th tergite yellow anteriorly. Male terminalia: Epandrium lacking pubescence, with ca. 7 setae near posterior margin per side (Fig. 19A). Cercus lacking pubescence (Fig. 19A). Surstylus pubescent (Fig. 19A). Paramere narrow basally, with ca. 6 sensilla distally (Fig. 19C). 2+3 <b>Measurements and indices.</b> BL = 2.58–2.89 mm in 5&amp;male;, 2.44–3.48 mm in 5&amp;female;, ThL = 1.20–1.47 mm in &amp;male;, 1.24–1.68 mm in &amp;female;, WL = 2.16–2.49 mm in &amp;male;, 2.22–3.00 mm in &amp;female;, WW = 0.89–1.11 mm in &amp;male;, 0.80–1.40 mm in &amp;female;, arb = 5/3 (6–7/3–4), avd = 0.72 (0.75–0.86), adf = 2.29 (1.73–2.50), flw = 1.87 (1.63–2.07), FW/HW = 0.30 (0.24–0.34), ch/o = 0.04 (0.04–0.06), prorb = 0.47 (0.40–0.87), rcorb = 0.36 (0.44–0.67), vb = 0.42 (0.33–0.75), dcl = damaged (0.31–0.60), presctl = damaged (0.27–0.58), sctl = 1.29 (1.20–1.56), sterno = damaged (0.53–0.75), orbito = 2.09 (1.83–2.50), dcp = 0.28 (0.20–0.33), sctlp = 1.01 (0.87–1.25), C = 2.22 (1.62–2.33), 4c = 0.90 (0.74– 1.18), 4v = 1.14 (1.05–1.55), 5x = 0.88 (0.97–1.83), ac = 1.96 (1.75–3.13), M = 0.45 (0.41–0.65), C3F = 0.72 (0.64–0.79). <b>Specimens examined.</b> CHINA: 5&amp;male; (SCAU, Nos 128487–91), Jiulongshan, Lishui, Zhejiang, 28°22'N, 118°53'E, alt. 1610m, 5.vii.2013, ex tussocks, K Liu; 5&amp;male;, 5&amp;female; (SCAU, Nos 128492–501), Wuyishan, on the boundary between Jiangxi and Fujian, 27°32'N, 117°24'E, alt. 1000m, 18.viii.2001, ex tussocks, HW Chen; 2&amp;female; (SCAU, Nos 128502, 03), Mangshan, Yizhang, Hunan, 24°55'N, 112°34'E, alt. 800m, 3.x.2004, ex tussocks, HL Cao; 2&amp;male; (SCAU, Nos 128645, 46), Chitou, Nantou, Taiwan, 23°46'N, 120°47'E, alt. 1159m, 16.x.2012, ex tussocks, HW Chen, JJ Gao; 1&amp;male;, 1&amp;female; (SCAU, Nos 128718, 19), Lugu, Nantou, Taiwan, 23°44'N, 120°47'E, alt. 350m, 18.x.2012, ex tree trunks, HW Chen; 1&amp;male;, 1&amp;female; (SCAU, Nos 128720, 21), Wulu, Taitung, Taiwan, 23°10'N, 121°02'E, alt. 740m, 28.x.2012, ex tree trunks, HW Chen; 2&amp;male;, 1&amp;female; (SCAU, Nos 128652–54), Nanling, Shaoguan, Guangdong, 24°38'N, 112°40'E, alt. 800m, 5.x.2004, ex tussocks, HL Cao; 3&amp;male; (SCAU, Nos 128624–26), Diaoluoshan, Lingshui, Hainan, 18°10'N, 108°52'E, alt. 600m, 3.xii.2003, ex tussocks, HW Chen; 4&amp;male; (SCAU, Nos 128714–17), Maoershan, Guilin, Guangxi, 25°51'N, 110°27'E, alt. 700m, 18, 19.x.2004, ex tussocks, HL Cao; 1&amp;male; (SCAU, No. 128506), Xincheng, Yingjiang, Yunnan, 24°47'N, 98°11'E, alt. 963m, 18.viii.2016, ex tussock, YQ Liu; 1&amp;male;, 4&amp;female; (SCAU, Nos 128647–51), Zhengxing, Jinggu, Yunnan, 23°20'N, 100°58'E, alt. 1100m, 23.vii.2009, ex tussocks, L Wang, L Wu; 9&amp;male;, 9&amp;female; (SCAU, Nos 128627–44), Yixiang, Pu'er, Yunnan, 22°47'N, 101°02'E, alt. 1200m, 2.x.2011, 13.v.2012, 12.xii.2012, ex tussocks, HW Chen, JJ Gao; 6&amp;male;, 5&amp;female; (SCAU, Nos 128476–86), Muyiji Park, Ximeng, Yunnan, 22°37'N, 99°36'E, alt. 1103m, 1–4.iv.2011, ex tussocks, JM Lu, YR Su; 7&amp;male;, 12&amp;female; (SCAU, Nos 129089–107), Muyiji Park, Ximeng, Yunnan, 22°37'N, 99°36'E, alt. 1203m, 29, 30.iv.2016, 3.v.2016, ex tree trunks, J Huang, YQ Liu, YL Wang, L Zhu; 5&amp;male;, 4&amp;female; (SCAU, Nos 128661–68, 128672), Hesong, Menghai, Yunnan, 21°50'N, 100°06'E, alt. 1700–1900m, 16.iv.2010, 26.iii.2011, 2–11.iv.2011, 11–13.v.2012, ex tussocks, HW Chen, JJ Gao, JM Lu, ZF Shao, YR Su, SJ Yan; 5&amp;male;, 8&amp;female; (SCAU, Nos 128655–60, 128725–31), Menglun, Mengla, Yunnan, 21°41'N, 101°25'E, alt. 700–780m, 24.xii.2003, 17.iv.2007, ex tussocks, HW Chen; 2&amp;male;, 1&amp;female; (SCAU, Nos 128722–24), Wangtianshu, Mengla, Yunnan, 21°28'N, 101°38'E, alt. 670m, 25.iv.2007, 13.iv.2010, ex tussocks, HW Chen; 18&amp;male;, 14&amp;female; (SCAU, Nos 128509–14, 129063–88), Guanlei, Mengla, Yunnan, 21°38'N, 101°10'E, alt. 562m, 15.x.2012, 20–24.iv.2016, ex tussocks, JJ Gao, J Huang, YQ Liu, YL Wang, L Zhu. <b>Distribution.</b> China (Zhejiang, Jiangxi, Hunan, Fujian, Taiwan, Guangdong, Hainan, Guangxi, Yunnan).
