description: <i>Leucophenga hyaloptera</i> Huang &amp; Chen, sp. nov. (Figs. 4A, 8A–C, 11D, 11E, 16A, 16B, 32) <b>Diagnosis.</b> This species is most similar to <i>L</i>. <i>forcipula</i> <b>sp. nov.</b> in having the pleura with a brown, longitudinal stripe above (Figs. 7F, 8C), the wing entirely hyaline (Figs. 3E, 4A), the colour patterns of abdominal tergites in females (Figs. 10H, 11E), and the shape and pubescence of epandrium, cercus, and surstylus (Figs. 28A, 32A), but can be distinguished from the latter in having the postocellar distinct (Fig. 8A); aedeagus straight, ventrolaterally with a long, apicodorsally acute process (Fig. 32D). <b>Description.</b> Ocellar triangle brownish yellow, with ca. 1 or 2 seta(e) above ocellar setae. Frons brownish yellow (Fig. 8A). Pedicel brownish yellow; first flagellomere yellow (Fig. 8A). Clypeus entirely brownish yellow. Palpus dark yellow (Fig. 8A). Mesonotum mostly brownish yellow (Fig. 8B). Postpronotal lobe yellow (Fig. 8C). Acrostichal setulae in ca. 12–14 irregular rows (Fig. 8B). Scutellum mostly brownish yellow, dark yellow at tip (Fig. 8B). Katepisternum mostly dark yellow (Fig. 8C). Mesopleuron yellow, brownish posteriorly (Fig. 8C). Wing (Fig. 4A): Costal vein between R 2+3 and R 4+5 distally with ca. 4–6 peg-like spinules on ventral surface; R 4+5 and M 1 nearly parallel distally; halter mostly yellowish, with a brown patch at knob (Fig. 8C). Abdominal tergites dark brown, 2nd tergite yellow medially and laterally, 3rd tergite mostly yellowish except for lateral region, only setigerous laterally in males (Fig. 11D), 3rd tergite yellow submedially and sublaterally in females (Fig. 11E), 4th and 5th tergites with yellow patches submedially and sublaterally. Male terminalia: Epandrium with ca. 7 setae near posterior margin and ventral corner per side (Fig. 32A). Hypandrium with 1 sensillum (Fig. 32B). Paramere expanded basally and rounded apically, with ca. 3 sensilla medially and ca. 5 ones distally (Fig. 32C). Aedeagus rectangular apically (Fig. 32D). <b>Measurements and indices.</b> BL = 2.66 mm in holotype (range in 2&amp;male; and 3&amp;female; paratrpes: 2.62–2.93 in &amp;male;, 2.40– 3.00 in &amp;female;), ThL = 1.39 mm (1.47–1.53 in &amp;male;, 1.27–1.50 in &amp;female;), WL = 2.54 mm (2.59–2.70 in &amp;male;, 2.30–2.83 in &amp;female;), WW = 1.21 mm (1.23–1.25 in &amp;male;, 1.10–1.20 in &amp;female;), arb = 7/2–3 (6–7/2–3), avd = 1.04 (0.73–0.96), adf = 1.58 (1.67– 2.05), flw = 1.92 (1.53–2.32), FW/HW = 0.37 (0.35–0.42), ch/o = 0.03 (0.03–0.04), prorb = 0.65 (0.60–0.74), rcorb = 0.60 (0.54–0.72), vb = 0.37 (0.31–0.46), dcl = damaged (0.40–0.50), presctl = 0.50 (0.45–0.55), sctl = 1.20 (1.17–1.34), sterno = damaged (0.76–0.84), orbito = 2.04 (1.90–2.38), dcp = 0.30 (0.23–0.28), sctlp = 0.99 (0.98– 1.11), C = 2.56 (2.32–2.48), 4c = 1.05 (1.08–1.35), 4v = 2.08 (1.89–2.32), 5x = 1.55 (1.36–1.60), ac = 1.71 (1.73– 1.86), M = 0.69 (0.58–0.71), C3F = 0.75 (0.71–0.76). <b>Type specimens.</b> Holotype &amp;male; (SCAU, No. 128733), CHINA: Muyiji Park, Ximeng, Yunnan, 22°37'N, 99°36'E, alt. 1103m, 2.iv.2011, ex tussock, JM Lu.
