Remarks: Species of this genus are supposed to be of type III ( McMurtry and Croft 1997; McMurtry et al. 2013), i.e. a polyphagous generalist predator. However, the biology of S. asiaticus remains totally unknown.

This species was already known from Vietnam from results of a previous survey ( Nguyen et al. 2016). Exact indications of locations were provided in this paper without providing any morphological data on the collected specimens. Measurements of collected specimens during this study are provided in table 5 and compared with those obtained from specimens collected in other countries of Asia and Indian Ocean. Measurements obtained match with most of previous measurements, especially with measurements of specimens from Thailand.
