According to the genus concept by Chant and McMurtry (2005), this species belongs to the asiaticus species group of the genus Scapulaseius as setae R 1 are inserted on the lateral margin of the dorsal shield of the adult female. The species group comprises 24 species. Species of the genus Scapulaseius are supposed to belong to the life-type III ( McMurtry and Croft 1997 ; McMurtry et al. 2013), i.e. a polyphagous generalist predator. Evans (1953) has indicated that the specimens collected were feeding in colonies of tetranychid mites. Despite these qualitative observations on the group, the biology of S. asiaticus itself remains totally unknown. The material examined had been collected in Java Island, Indonesia ( Evans 1953), in Mauritius Island ( Kreiter and Abo-Shnaf 2020b ; Ferragut and Baumann 2019) and in Vietnam (Kreiter et al. 2020b).
