( Figs. 10A, 10B , 45 ) Diagnosis. This species is similar to S . ( S .) hirticlavata sp. nov. in the face mostly yellow, black near lower margin, but can be distinguished from the latter by having the first flagellomere yellow on basal 2/3, black on distal 1/3 ( Fig. 10B ); the facial carina present; the pregonite small, with 7 or 8 sensilla, lacking long pubescence distally ( Fig. 45B, C ); the aedeagus with 1 pair of sclerotized and 1 pair of membranous lobe-shaped processes ( Fig. 45B, C ). Description. Male: Clypeus and palpus yellow. Mesonotum and scutellum yellow ( Fig. 10A ). Katepisternum yellowish ( Fig. 10B ). Halter mostly grey ( Fig. 10B ). Fore femur with 3 strong setae on distal part of posteroventral surface. Abdominal tergites yellow ( Fig. 10A, B ); sternites yellow, about 2 times as wide as long. Male terminalia ( Fig. 45 ): Epandrium with 11 setae on dorsal to posterior portions per side ( Fig. 45A ). Surstylus with some setulae near distal margin, lacking pubescence ( Fig. 45A ). Cercus with much pubescence ( Fig. 45A ). Hypandrium slightly expanded anteromedially ( Fig. 45B, C ). Aedeagal sheath acute apically, with 1 pair of acute processes subapically ( Fig. 45D, E ). Subepandrial sclerite broadened, slightly expanded distally ( Fig. 45F ). Measurements and indices.
