description: <i>Leucophenga valvata</i> Huang &amp; Chen, sp. nov. (Figs. 4E, 8M–O, 11J–L, 12A–D, 16I, 16J, 36) <b>Diagnosis.</b> This species is most similar to <i>L</i>. <i>delta</i> <b>sp. nov.</b> in the having the postocellar setae minute (Figs. 7A, 8M), the mesonotum and scutellum mostly brownish yellow (Figs. 7B, 8N), the pleura lacking stripe above (Figs. 7C, 8O), and the wing mostly clouded (Figs. 3D, 4E), but can be distinguished from the latter in having the epandrium lacking pubescence and seta (Fig. 36A); surstylus caudally acute, lacking pubescence, with setae along caudal margin only (Fig. 36A); paramere slender, basally acute (Fig. 36C); aedeagus distally slightly curved ventrad, laterally with a long, apically narrow process (Fig. 36D). There is intraspecific variation in abdominal tergite colour pattern in this species (Figs. 11J–L, 12A–D). This species is comprised of a large proportion of “shortened” (Figs. 11J–L, 12A) and a few “normal” specimens (Fig. 12B), but there is no other conspicuous intraspecific morphological variation between these two kinds of specimens. Therefore, all the specimens were identified as a single new species to avoid further confusion. <b>Description.</b> Ocellar triangle dark brown, with ca. 2 or 3 setae above ocellar setae. Frons brownish (Fig. 8M). Orb 3 and Orb 2 parallel (Fig. 8M). Pedicel brownish yellow; first flagellomere yellow (Fig. 8M). Clypeus entirely brownish. Palpus brownish yellow (Fig. 8M). Postpronotal lobe brownish yellow (Fig. 8O). Acrostichal setulae in ca. 14–16 irregular rows (Fig. 8N). Katepisternum and mesopleuron mostly yellow to dark yellow (Fig. 8O). Wing (Fig. 4E): mostly clouded; costal vein between R 2+3 and R 4+5 distally with ca. 5–7 peg-like spinules on ventral surface; R 4+5 and M 1 slightly convergent distally; halter mostly yellow, with a dark yellow to dark brown patch at knob (Fig. 8O). Abdominal tergites dark brown to black, 2nd tergite usually yellow medially and laterally, 3rd tergite usually yellow anteriorly and laterally, entirely setigerous even in the “shortened” specimens (Figs. 11J–L, 12A, B), 4th tergite usually yellow anteriorly (Figs. 11J–L, 12A–D). Male terminalia: Cercus lacking pubescence (Fig. 36A). Paramere narrow apically, with ca. 7 sensilla distally (Fig. 36C). <b>Measurements and indices.</b> BL = 4.13 mm in holotype (range in 5&amp;male; and 5&amp;female; paratrpes: 3.82–4.18 in &amp;male;, 3.13– 3.53 in &amp;female;), ThL = 2.11 mm (1.87–2.09 in &amp;male;, 1.60–1.70 in &amp;female;), WL = 3.59 mm (3.19–3.49 in &amp;male;, 2.67–2.83 in &amp;female;), WW = 1.59 mm (1.43–1.61 in &amp;male;, 1.20–1.37 in &amp;female;), arb = 6–7/4 (6–7/3–4), avd = 1.05 (0.84–1.10), adf = 2.45 (1.89– 2.73), flw = 2.31 (1.87–2.73), FW/HW = 0.24 (0.22–0.34), ch/o = 0.06 (0.03–0.06), prorb = 0.62 (0.60–0.81), rcorb = 0.67 (0.70–0.90), vb = 0.60 (0.44–0.70), dcl = damaged (0.38–0.60), presctl = 0.59 (0.42–0.58), sctl = damaged (1.16–1.25), sterno = damaged (0.59–0.83), orbito = 1.07 (1.16–1.78), dcp = 0.24 (0.23–0.38), sctlp = 1.16 (1.01– 1.33), C = 2.14 (1.78–2.16), 4c = 1.24 (1.14–1.32), 4v = 1.77 (1.51–1.84), 5x = 0.91 (0.85–1.28), ac = 2.66 (2.63– 3.49), M = 0.42 (0.39–0.58), C3F = 0.75 (0.71–0.83). <b>Type specimens.</b> Holotype &amp;male; (SCAU, No. 128737), CHINA: Muyiji Park, Ximeng, Yunnan, 22°37'N, 99°36'E, alt. 1103m, 4.iv.2011, ex tussock, JM Lu.
