- 🛺 The type genus of this family has been placed in the family Segnochrobactraceae Akter et al. 2020. Publication: diCenzo GC, Yang Y, Young JPW, Kuzmanovic N.

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