Fronto-orbital plate black above, brownish yellow below. Pedicel yellow; first flagellomere dark brown. Face black on upper two-thirds, yellow on lower margin. Clypeus yellow. Scutum black medially, brownish yellow laterally. Basisternum yellow. Scutellum black basally, yellow distally. Wing brown anteriorly, paler posteriorly, dark brown on all crossveins. Fore femur with one row of three or four suberect setae on ventral surface. Abdominal tergites black. Sternites dark brown, broadened, wider than length. Male terminalia: cercus lacking pubescence (Figure 9A). Surstylus with one prensiseta on apical margin (Figure 9A). Tenth sternite slightly expanded medially (Figure 9C). Hypandrium slightly roundly expanded anteromedially (Figure 9D). Paramere distinctly protruded and with two sensilla (Figure 9C, D). Aedeagus broadened distally, with pubescence anteromedially and sporadic, minute processes (Figure 9D, E). <i>Measurements</i> BL = 3.28 mm in holotype (range in five &amp;male; and five &amp;female; paratypes: 2.84–3.32 in &amp;male;, 3.2–3.64 in &amp;female;), ThL = 1.28 mm (1.32–1.68 in &amp;male;, 1.50–1.84 in &amp;female;), WL = 2.64 mm (2.28–2.80 in &amp;male;, 2.36–2.96 in &amp;female;), WW = 1.16 mm (1.00– 1.20 in &amp;male;, 1.00– 1.40 in &amp;female;), arb = 7 <i>/</i> 4 (7–10 <i>/</i> 4–6), avd = 0.83 (0.78–0.90), adf = 1.20 (1.14–1.67), flw = 2.17 (1.71–2.17), FW <i>/</i> HW = 0.42 (0.35–0.47), ch <i>/</i> o = 0.14 (0.15–0.23), prorb = 1.07 (0.89–1.15), rcorb = 0.67 (0.69–1.00), vb = 0.31 (0.36–0.55), dcl = 0.43 (0.24–0.56), presctl = 0.48 (0.45–0.88), sctl = 1.40 (1.65–1.88), sterno = 0.44 (0.42–0.75), orbito = 1.80 (1.43–2.25), dcp = 0.21 (0.14–0.29), sctlp = 2.00 (1.40–2.11), <i>C</i> = 1.76 (1.80–2.03), 4c = 1.23 (1.06–1.28), 4v = 1.90 (1.50–1.92), 5x = 1.20 (1.27–1.82), ac = 18.50 (11.00–18.50), <i>M</i> = 0.40 (0.47–0.64), C3F = 0.79 (0.69–0.82). <i>Type material</i> Holotype &amp;male; (SCAU, No. 121295), CHINA: Mengla, Xishuangbanna, Yunnan, altitude 570 m, 22 April 2007, HW Chen.
