description: <i>Leucophenga brevitabulata</i> Huang &amp; Chen, sp. nov. (Figs. 3C, 6M–O, 10D, 10E, 14I, 14J, 26) <b>Diagnosis.</b> This species is most similar to <i>L</i>. <i>fuscipalpula</i> <b>sp. nov.</b> in the colour patterns of abdominal tergites in both male (Fig. 10D, I) and female (Fig. 10E, J), but can be distinguished from the latter in having the paramere basally narrow (Fig. 26C); aedeagus apically hook-shaped, laterally with a long, acute, distoventrally expanded process (Fig. 26D); see below for that species. <b>Description.</b> Ocellar triangle dark brown, with ca. 2 or 3 setae above ocellar setae. Frons brownish (Fig. 6M). Pedicel brownish yellow; first flagellomere yellowish (Fig. 6M). Clypeus entirely brownish. Palpus brownish (Fig. 6M). Mesonotum brownish yellow, brownish in front of scutellum (Fig. 6N). Postpronotal lobe yellow (Fig. 6O). Acrostichal setulae in ca. 14–16 irregular rows (Fig. 6N). Scutellum entirely dark brown to black (Fig. 6N). Pleura with a brownish to brown, longitudinal stripe above (Fig. 6O). Katepisternum and mesopleuron mostly yellow (Fig. 6O). Wing (Fig. 3C): distally clouded; costal vein between R 2+3 and R 4+5 distally with ca. 5 or 6 peg-like spinules on ventral surface; R 4+5 and M 1 slightly divergent distally; halter mostly yellowish, with a brownish to brown patch at knob (Fig. 6N). Abdominal tergites dark brown to black, 2nd tergite yellow medially and laterally, 3rd and 4th tergites anteriorly yellow (Fig. 10D, E), 3rd tergite entirely setigerous, sometimes setigerous laterally and only on posterior margin in males (Fig. 10D). Male terminalia: Epandrium lacking pubescence, with ca. 16 setae near posterior and ventral margins per side (Fig. 26A). Cercus lacking pubescence (Fig. 26A). Surstylus pubescent (Fig. 26A). Hypandrium with 2 sensilla (Fig. 26B). Paramere with ca. 10 sensilla distally (Fig. 26C). <b>Measurements and indices.</b> BL = 4.01 mm in holotype (range in 5&amp;male; and 5&amp;female; paratypes: 3.24–4.13 in &amp;male;, 3.55– 4.13 in &amp;female;), ThL = 1.91 mm (1.64–2.31 in &amp;male;, 1.72–1.93 in &amp;female;), WL = 3.14 mm (2.89–3.33 in &amp;male;, 2.75–3.08 in &amp;female;), WW = 1.51 mm (1.33–1.82 in &amp;male;, 1.25–1.57 in &amp;female;), arb = 7/3 (7–9/3–4), avd = 0.73 (0.57–1.00), adf = 2.26 (1.50– 2.40), flw = 2.12 (1.67–2.36), FW/HW = 0.30 (0.27–0.38), ch/o = 0.03 (0.03–0.04), prorb = damaged (0.49–0.60), rcorb = 0.70 (0.53–0.73), vb = 0.47 (0.45–0.60), dcl = 0.46 (0.34–0.50), presctl = 0.63 (0.43–0.80), sctl = damaged (1.18–1.67), sterno = 0.66 (0.42–0.70), orbito = 2.03 (1.63–2.33), dcp = 0.29 (0.19–0.33), sctlp = 1.03 (1.03–1.17), C = 2.26 (2.11–2.56), 4c = 0.98 (0.84–1.12), 4v = 1.27 (1.16–1.51), 5x = 0.83 (0.54–0.86), ac = 1.79 (1.45–2.13), M = 0.34 (0.28–0.39), C3F = 0.72 (0.59–0.67). <b>Type specimens.</b> Holotype &amp;male; (SCAU, No. 128460), CHINA: Wangtianshu, Mengla, Yunnan, 21°28'N, 101°38'E, alt. 600m, 22.iv.2007, ex tree trunk, HW Chen.
