Notes:
- ⏲ According to Labeda et al. (2016), this species is a later heterotypic synonym of Streptomyces hirsutus Ettlinger et al. 1958 (Approved Lists 1980). Publication: Labeda DP, Rong X, Huang Y, Doroghazi JR, Ju KS, Metcalf WW.

- ❗ Streptomyces cyanoalbus is the correct name instead if this species is regarded as a separate species (i.e., if its nomenclatural type is not assigned to another species whose name is validly published, legitimate and not rejected and has priority) within a separate genus Streptomyces.
