Steganina  ( Figure 6)    Diagnosis This species is similar to  S. cyclophylla Chen and Chen, 2009afrom south-western Chinain the shapes of hypandrium and aedeagus, can be differentiated from it by having the cercus lacking pubescence ( Figure 6A), the paramere absent or undistinguishable ( Figure 6D, E), the dorsal projection of gonopods slightly expanded, but not protruded ( Figure 6G). In  S. cyclophylla: the cercus with pubescence dorsally, the paramere with ca. 4 sensilla, the dorsal projection of gonopods strongly protruded and curved drosad (as in Chen and Chen 2009a, figs 10–13).    Description Frons and fronto-orbital plate nearly black, lacking minute setulae. Pedicel brown; first flagellomere black. Face brown on upper two-thirds, yellow on lower margin. Clypeus yellow. Scutum brown medially, brownish yellow laterally. Katepisternum yellow. Basisternum yellow. Scutellum brown. Wing brown anteriorly, paler posteriorly, dark brown on all crossveins. Fore femur with one row of four suberect setae on ventral surface. Abdominal tergites mostly dark brown. Sternites brown, much broadened, wider than length. Male terminalia: surstylus with serrated, minute processes, lacking prensiseta ( Figure 6B). Tenth sternite strongly broadened ( Figure 6C). Hypandrium slightly square anteromedially ( Figure 6D). Dorsal projection of gonopods with serrated, minute processes ( Figure 6F, G). Aedeagus round distally in ventral view, with pubescence medially and apically on opening ( Figure 6D, E).   Measurements BL = 3.28 mmin holotype(range in three ♂and five ♀ paratypes: 2.80–3.68 in ♂, 3.20–3.84 in ♀), ThL = 1.70 mm( 1.40–1.74 in ♂, 1.68–1.92 in ♀), WL = 3.40 mm( 2.08–3.08 in ♂, 2.56–3.16 in ♀), WW = 1.38 mm( 1.20–1.40 in ♂, 1.44–1.60 in ♀), arb = 13 /5 (12–14 /4–6), avd = 0.77 (0.64–1.43), adf = 2.17 (1.29–1.83), flw = 2.17 (1.72–2.17), FW /HW = 0.37 (0.38–0.47), ch /o = 0.16 (0.14–0.19), prorb = 0.94 (0.92–1.25), rcorb = 0.83 (0.63–0.84), vb = 0.55 (0.31–0.47), dcl = 0.56 (0.33–0.83), presctl = 0.83 (0.55–0.87), sctl = 1.87 (1.33–2.25), sterno = 0.65 (0.34–0.61), orbito = 1.80 (1.50–2.20), dcp = 0.31 (0.16–0.38), sctlp = 2.11 (2.10–2.33), C= 2.09 (1.76–2.22), 4c = 1.16 (1.03–1.30), 4v = 1.79 (1.25–2.00), 5x = 1.29 (1.07–1.78), ac = 22.00 (16.50–22.50), M= 0.47 (0.37–0.56), C3F = 0.71 (0.57–0.76).    Type material   Holotype ♂( SCAU, No. 121207), CHINA: Mount Maoer, Guilin, Guangxi, altitude  700 m,  19 October 2004, HW Chen.  Paratypes: five ♂, five ♀( two ♂and two ♀in KIZ; three ♂and three ♀in SCAU, Nos. 121208–13), HL Cao, HW Chen, F Xu, XL Zhang, same data as holotype;  one ♂, one ♀( SCAU, Nos. 121214, 15), Guangzhou, Guangdong, 23 ◦40 ′N, 113 ◦34 ′E, altitude  320 m,  3 November 2003, HW Chen;  one ♂( SCAU, No. 121216), Mount Wuliang, Jingdong, Yunnan, 24 ◦32 ′N, 101 ◦01 ′E, altitude  2230 m, 27,  28 July 2006, T Li.    Etymology A combination of the Latin words: latus+ gena, referring to the broad gena.    Distribution   China( Guangdong, Guangxi, Yunnan). 2004-10-19 SCAU HW Chen China 700 Guilin Mount Maoer 13 2005 1 1 Guangxi holotype 2004-10-19 KIZ, SCAU HL Cao & HW Chen & F Xu & XL Zhang China 700 Guilin Mount Maoer 13 2005 6 3 3 Guangxi paratype 2003-11-03 SCAU HW Chen China 320 23.666666 Guangzhou 1254 113.566666 13 2005 2 1 1 Guangdong paratype 2006-07-28 SCAU, T Li China 2230 24.533333 Jingdong 1250 101.01667 Mount Wuliang 13 2005 1 1 Yunnan paratype [211,659,1082,1106] China Guangdong 13 2005 1 Guangdong
