( Figs. 12G, 12H View FIGURE 12 , 56 View FIGURE 56 )
Diagnosis. This species differs from the other Steganina species in having the pregonite basally with a pair of large, pubescent flaps ( Fig. 56B, C View FIGURE 56 ); the aedeagus distodorsally triangular, distolaterally protruding, with numerous minute, serrated processes near margin ( Fig. 56B, C View FIGURE 56 ).
Description. Male and female: First flagellomere brown. Clypeus yellow. Mesonotum dark brown to black medially, brown laterally ( Fig. 12G View FIGURE 12 ). Katepisternum yellowish, brownish on anterior corner ( Fig. 12H View FIGURE 12 ). Scutellum black, yellow at tip ( Fig. 12G View FIGURE 12 ).Halter mostly grey ( Fig. 12H View FIGURE 12 ). Fore femur with a row of 3 or 4 long setae on distal part of posteroventral surface. Abdominal tergites mostly black ( Fig. 12G, H View FIGURE 12 ); sternites yellow, slightly wider than long. Male terminalia ( Fig. 56 View FIGURE 56 ): Epandrium with ca. 12 setae on dorsal to posterior portions per side ( Fig. 56A View FIGURE 56 ). Surstylus with some minute, serrated processes on outer surface, 1 peg-like tooth and several setulae near distal margin, lacking pubescence ( Fig. 56A View FIGURE 56 ). Cercus lacking pubescence ( Fig. 56A View FIGURE 56 ). Hypandrium expanded anteromedially ( Fig. 56B, C View FIGURE 56 ). Pregonite fused and large, with 3 sensilla medially ( Fig. 56B, C View FIGURE 56 ). Aedeagal sheath distally dorsad curved and with several minute, serrated processes ( Fig. 55D, E View FIGURE 55 ). Subepandrial sclerite slightly expanded distally ( Fig. 55F View FIGURE 55 ).
