Zoobank registration: u r n: l s i d: z o o b a n k. org:act: 90220A73-AEB1-40E3-9F6D-69C6F1A15FF3
Holotype: ♂ (SCAU, No. 122179; BOLD process ID BDORF002–13), China: Hesong, Menghai, Yunnan, 21.833°N, 100.133°E, 1940 m a.s.l., 10–12.v.2012, tree trunk, H. W. Chen.
Paratype: China: 1♂, 6♀ (SCAU, Nos 122180–86), same data as holotype; 1♂, 1♀, (SCAU, Nos 124707, 08; BOLD process ID BDORF 001– 13 in ♂), same data as holotype except 6.iv.2011, J. M. Lu; 1♂, 4♀ (SCAU, Nos 121887–91), Yixiang, Pu’er, Yunnan, 22.700°N, 101.150°E, 1400 m a.s.l., 13.v.2012, ex tree trunks, H. W. Chen.
Etymology: The name refers to the tachinid genus Zebromyia Malloch, 1929, which is so named for its striped abdomen (from Greek ζέβρα, zebra, and Μυια, muscles) referring to the mesoscutum with its longitudinal markings.
Diagnosis: This species resembles S. dianensis Chen & Chen, 2012 in male terminalia (Fig. 7), but can be distinguished from the latter species by mesoscutum being brown, submedially with broad, yellow longitudinal strips (Fig. 4E, F), the opening of aedeagus heart-shaped in ventral view (Fig. 7C). In S. dianensis: colour patterns of mesoscutum is similar to the new species S. zopheria (Fig. 4G, H); opening of aedeagus narrow, slit-like in ventral view (as fig. 10 in Chen & Chen, 2012).
