本属に含まれるアザミウマは全て、ハダニ類を捕食している。本種は台湾から記載され、日本では北海道以外から記録されている。かつてムツテンアザミウマの学名にはS. sexmaculatus (Pergande, 1891)が使用されていたが、この種は北米のみに分布し、前胸背板の後縁付近に1対の刺毛を持つことでS. takahashiiと区別できる。

All 16 species of the genus are predators of the tetranychid mites. This species was described from Taiwan and has been also recorded from Japan other than Hokkaido so far. For the long time, this species was identified as S. sexmaculatus (Pergande, 1891) in Japan, but that species is distributed only in the North America and is distinguished from S. takahashii by the pronotum with a pair of discal setae near posterior margin.
