(Figs. 9G, 9H, 44)
Diagnosis. This species is similar to S. (S.) jianqinae Zhang, Tsaur, & Chen, 2014 in the shape of male terminalia (as fig. 8 in Zhang et al. 2014, Fig. 44), but can be distinguished from the latter by having the first flagellomere yellow on basal 2/3, black on distal 2/3 (Fig. 9H); the pregonite fused basally, with much long pubescence distally (Fig. 44C, D).
Description. Male and female: Face mostly yellow, black near lower margin; facial carina absent. Clypeus yellow. Mesonotum yellow, with blurry longitudinal stripes (Fig. 9G). Katepisternum yellowish (Fig. 9H). Scutellum yellow, brown along margin in male (Fig. 9G). Halter mostly yellow (Fig. 9H). Fore femur with a row of 3 strong setae on distal part of posteroventral surface. Abdominal tergites brownish (Fig. 9G, H); sternites yellow, about 2 times as wide as long. Male terminalia (Fig. 44): Epandrium with 4 setae near dorsal portion per side (Fig. 44A). Surstylus with numerous setulae on outer surface and some pubescence medially (Fig. 44A, B). Cercus with much pubescence (Fig. 44A). Hypandrium expanded anteromedially (Fig. 44C, D). Aedeagus expanded distally, with a pair of rod-like processes (Fig. 44C, D). Aedeagal sheath slightly saddle-shaped (Fig. 44E, F). Subepandrial sclerite slightly quadrate (Fig. 44G).

Distribution. China (Yunnan).
Etymology. A combination of the Latin words '' hirtus '' (= hirsute) and '' clavatus '' (= rod-like), referring to the pregonite distally with long pubescence.
