Distribution. China (Yunnan, Hainan, Taiwan); Pakistan, Philippines, Thailand, Burma, Ceylon, India, Malaya, Nepal, Pakistan ( Beaver et al., 1977; Knutson, 1977).

Remarks. This species is similar to S. lobifera in having a cochleate vesicle and distinct velvet black spots on the frons but differs from S. lobifera in lacking parafacial spots. It can be distinguished from S. lobifera by the present of orbital and scutellar setae.
