description: <i>Leucophenga glabtabulata</i> Huang &amp; Chen, sp. nov. (Figs. 3G, 7J–L, 10K, 10L, 15G, 15H, 30) <b>Diagnosis.</b> This species is somewhat similar to <i>L</i>. <i>hyaloptera</i> <b>sp. nov.</b> in the shape and pubescence of epandrium, cercus, and surstylus (Figs. 30A, 32A), and the shape of paramere (Figs. 30C, 32C), but can be distinguished from the latter in having the postocellar setae minute (Fig. 7J); colour patterns of abdominal tergites in both male (Fig. 10K) and female (Fig. 10L); aedeagus laterally mostly covered by its long, bifurcated processes (Fig. 30D); see below that species. <b>Description.</b> Ocellar triangle dark brown, with ca. 1–3 seta(e) above ocellar setae. Frons brownish (Fig. 7J). Orb 3 and Orb 2 parallel (Fig. 7J). Pedicel brownish; first flagellomere yellow (Fig. 7J). Clypeus entirely brownish yellow. Palpus brownish yellow (Fig. 7J). Mesonotum mostly brownish yellow (Fig. 7K). Postpronotal lobe dark yellow (Fig. 7L). Acrostichal setulae in ca. 14–16 irregular rows (Fig. 7K). Scutellum mostly brownish yellow, brownish laterally (Fig. 7K). Pleura with a brown, longitudinal stripe above (Fig. 7L). Katepisternum and mesopleuron mostly dark yellow (Fig. 7L). Wing (Fig. 3G): slightly clouded; costal vein between R 2+3 and R 4+5 distally with ca. 5 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. 7K). Abdominal tergites dark brown, 2nd tergite yellow medially, 3rd tergite mostly yellowish except for small lateral region, setigerous only on lateral posterior margin in males (Fig. 10K), 3rd tergite yellow anteriorly and laterally in females (Fig. 10L), 4th tergite yellowish to yellow anteriorly. Male terminalia: Epandrium with ca. 11 setae near posterior and ventral margins per side (Fig. 30A). Paramere narrow basally, with ca. 7 sensilla distally (Fig. 30C). <b>Measurements and indices.</b> BL = 3.25 mm in holotype (3.20 in 1&amp;female; paratype), ThL = 1.65 mm (1.53), WL = 2.61 mm (2.70), WW = 1.11 mm (1.23), arb = 6/4 (8/4), avd = 1.06 (0.94), adf = 2.00 (2.13), flw = 2.03 (2.13), FW/ HW = 0.34 (0.33), ch/o = 0.04 (0.03), prorb = 0.53 (damaged), rcorb = 0.85 (0.81), vb = 0.38 (0.50), dcl = damaged (damaged), presctl = 0.46 (damaged), sctl = 1.07 (1.11), sterno = damaged (damaged), orbito = 1.29 (1.25), dcp = 0.29 (0.29), sctlp = 0.97 (1.12), C = 1.88 (1.96), 4c = 1.38 (1.45), 4v = 2.13 (2.12), 5x = 1.04 (1.12), ac = 2.79 (2.67), M = 0.62 (0.58), C3F = 0.85 (0.83). <b>Type specimens.</b> Holotype &amp;male; (SCAU, No. 128732), CHINA: Menglun, Mengla, Yunnan, 21°41'N, 101°25'E, alt. 780m, 17.iv.2007, ex tussock, HW Chen. Paratype: CHINA: 1&amp;female; (SCAU, No. 128610), same data as holotype. <b>Distribution.</b> China (Yunnan). <b>Etymology.</b> A combination of the Latin words: “ <i>glabellus</i> ” (= glabrous) and “ <i>tabulatus</i> ” (= plate), referring to the abdominal 3rd tergite medially non-setigerous in males.
