Stegana (Steganina) glaucopalpula Cui & Chen View in CoL , sp. nov.

( Figs. 9C, 9D View FIGURE 9 , 42A–C View FIGURE 42 )

Diagnosis. This species is similar to S. (S.) curvitabulata sp. nov. in the laterally curlied 8th sternite ( Figs. 35B View FIGURE 35 , 42B View FIGURE 42 ), but can be distinguished from the latter by having the palpus large, mostly yellow, slightly grey distally ( Fig. 9D View FIGURE 9 ); the epiproct lacking sensilla, with several setae ( Fig. 42A View FIGURE 42 ); the 8th sternite glabrous ( Fig. 42B View FIGURE 42 ).

Description. Female: First flagellomere black. Clypeus brownish medially, yellow laterally. Mesonotum yellow, with broad, brown longitudinal stripes medially ( Fig. 9C View FIGURE 9 ). Katepisternum mostly yellow, brownish posteriorly ( Fig. 9D View FIGURE 9 ). Scutellum brown ( Fig. 9C View FIGURE 9 ). Halter mostly grey ( Fig. 9D View FIGURE 9 ). Fore femur with a row of 4 or 5 sturdy setae on distal part of posteroventral surface. Abdominal tergites dark brown ( Fig. 9C, D View FIGURE 9 ); sternites brown, about 2 times as wide as long. Female terminalia ( Fig. 42A–C View FIGURE 42 ): Epiproct lacking pubescence ( Fig. 42A View FIGURE 42 ). Cercus and hypoproct with numerous setae and much pubescence ( Fig. 42A, C View FIGURE 42 ).

Measurements and indices. BL = 2.88 mm in holotype, ThL = 1.59 mm, WL = 2.46 mm, WW = 1.21 mm, arb = 8/5, avd = 0.77, adf = 1.30, flw = 2.50, FW/HW = 0.33, ch/o = 0.13, prorb = damaged, rcorb = damaged, vb = 0.58, dcl = damaged, presctl = 0.79, sctl = damaged, sterno = damaged, orbito = 1.96, dcp = 0.33, sctlp = 1.33, C = 2.48, 4c = 0.89, 4v = 1.83, 5x = 1.73, ac = 8.89, M = 0.58, C3F = 0.67.

Type material. Holotype ♀ ( SCAU, No. 125753, DNA #2704, 2777), CHINA: Wugongshan, Kaohsiung, Taiwan, alt. 340m, 15.vi.2011, ex tree trunk, X.Y. Liu.

Distribution. China (Taiwan).

Etymology. A combination of the Latin words '' glaukos " (= grey) and '' palpulus '' (= palpus), referring to the grey distally palpus.
