description: <i>Stegana</i> (<i>Steganina</i>) <i>convena</i> sp. nov. (Figure 1) <i>Diagnosis</i> This species is similar to <i>S. serratoprocessata</i> Chen and Chen, 2009a from southern China in the shapes of 10th sternite and aedeagus, can be differentiated from it by having the cercus lacking pubescence (Figure 1A), the surstylus lacking prensiseta (Figure 1A), the aedeagus sub-basally with two serrated processes per side (Figure 1C, D). In <i>S. serratoprocessata</i>: cercus pubescent and surstylus with one prensiseta on apical margin (as in Chen and Chen 2009a, figs 21, 22); aedeagus with numerous serrated, minute processes submedially (as in Chen and Chen 2009a, figs 24, 25). <i>Description</i> Frons brown. Fronto-orbital plate yellow. Pedicel yellow; first flagellomere black. Face black on upper two-thirds, yellow on lower margin. Clypeus yellow. Scutum yellow, with brown patches, and longitudinal stripe: medially broad and sublaterally thin. Basisternum yellow. Scutellum brown medially, yellow along margin. Wing brown anteriorly, yellowish posteriorly, dark brown on all crossveins. Fore femur with one row of four suberect setae on ventral surface. Abdominal tergites first to third mostly dark brown, each with one yellow patch on lateral margin; fourth to sixth mostly yellow, each with dark brown, narrow band along posterior margin. Sternites brown, slightly broader than length. Male terminalia: surstylus distally with numerous serrated, minute processes on outer surface (Figure 1A). Tenth sternite slightly oblong medially (Figure 1B). Hypandrium roundly expanded anteromedially (Figure 1C). Paramere slightly protruded, with ca. four sensilla (Figure 1C, D). Dorsal projection of gonopods with numerous serrated, minute processes (Figure 1C, D). Aedeagus slightly sclerotized posteromedially, protruded apicomedially (Figure 1D); with dense pubescence and numerous serrated processes along anterior margin of opening (Figure 1C, D). <i>Measurements</i> BL = 3.67 mm in holotype (range in two &amp;male; and three &amp;female; paratypes: 3.32–3.64 in &amp;male;, 3.32–3.80 in &amp;female;), ThL = 1.60 mm (1.24–1.72 in &amp;male;, 1.40–1.44 in &amp;female;), WL = 2.30 mm (2.20–2.88 in &amp;male;, 2.52–2.68 in &amp;female;), WW = 1.17 mm (1.00– 1.40 in &amp;male;, 1.12–1.32 in &amp;female;), arb = 16 <i>/</i> 7 (14–16 <i>/</i> 5–7), avd = 0.70 (0.63–0.88), adf = 1.67 (1.60–2.25), flw = 2.00 (2.00–2.40), FW <i>/</i> HW = 0.52 (0.40–0.49), ch <i>/</i> o = 0.16 (0.17–0.26), prorb = 1.14 (0.67–1.17), rcorb = 0.86 (0.60–0.83), vb = 0.55 (0.42–0.63), dcl = 0.58 (0.38–0.67), presctl = 0.63 (0.56–0.83), sctl = 1.46 (1.39–1.72), sterno = 0.59 (0.59–0.80), orbito = 1.43 (1.67–2.00), dcp = 0.31 (0.21–0.33), sctlp = 2.83 (1.36–1.70), <i>C</i> = 1.55 (1.88–2.08), 4c = 1.47 (0.92–1.72), 4v = 1.80 (1.70–1.83), 5x = 1.80 (1.15–1.80), ac = 22.00 (16.00–18.00), <i>M</i> = 0.93 (0.50–0.68), C3F = 0.65 (0.61–0.73). <i>Type material</i> Holotype &amp;male; (SCAU, 121115), CHINA: Menglun, Mengla, Xishuangbanna, Yunnan, 21 ◦ 41 ′ N, 101 ◦ 25 ′ E, altitude 700 m, 17–19 April 2007, HW Chen.
