    <i>Phortica</i> (<i>Ashima</i>) <i>eseta</i> Chen, sp. nov. <p>(Figs 4–7)</p> <p> <b>Diagnosis.</b> This species is similar to <i>P. afoliolata</i> Chen & Toda in Chen <i>et al.</i>, 2005 from China and Myanmar, and <i>P. xishuangbanna</i> Cheng & Chen in Cheng <i>et al</i>., 2008 from China in the plumose arista; it can be differentiated from them by having the vertical process of gonopods distinctly asymmetric, nearly entirely sclerotized and pointed apically (Figs 6, 7), aedeagus comprised of 2 sclerites entirely separated from median rod (Figs 6, 7, aed sc), while in <i>P. xishuangbanna</i> aedeagus is comprised of 3–4 sclerites of different shape.</p> <p> <b>Description.</b> Frons brown, with thick and dense interfrontal setae. Pedicel and first flagellomere grayish yellow. Arista plumose, not swollen apically in male. Face brown, with yellowish white patches on lower corners. Clypeus medially white, laterally black. Thorax and scutellum orange brown. Legs yellow, with brown spot submedially on each femur and 2 brown rings on each tibia; fifth tarsomere of male foreleg without long seta apically. Abdominal third to fifth sternites longer than wide; sixth sternite with a few long setae laterally. Male terminalia: Surstylus distally with pubescence, several setae and ca. 20 prensisetae on ventral margin to inner surface (Fig. 5). Paramere finely serrated apically, with 3 sensilla submedially (Figs 6, 7). Aedeagus with developed outer membrane (Figs 6, 7).</p> <p> <b>Measurements.</b> BL = 3.98 mm in holotype (3.44 mm in 13 paratype), ThL = 1.69 mm (1.52 mm), WL = 2.72 mm (2.48 mm), WW = 1.20 mm (1.20 mm), arb = 5/4 (5-6/4), avd = 0.50 (0.50), adf = 1.20 (1.20), flw = 1.50 (1.50), FW/HW = 0.38 (0.40), ch/o = 0.07 (0.07), prorb = 1.10 (1.30), rcorb = 0.50 (0.60), vb = 0.50 (0.35), dcl = 0.50 (0.55), presctl = 0.57 (0.55), sctl = 0.98 (1.00), sterno = 1.00 (0.90), orbito = 1.80 (1.50), dcp = 0.30 (0.32), sctlp = 1.20 (1.10), C = 2.05 (1.94), 4c = 1.58 (1.80), 4v = 2.42 (3.10), 5x = 0.88 (1.14), ac = 4.75 (4.50), M = 0.58 (0.80), C3F = 0.68 (0.67).</p> <p> <b>Type materials.</b> Holotype 3 (SEHU), MALAYSIA: Poring, Sabah, 30.xii.1998, MJ Toda.
