By Western pentatonic scale (which shows up in other musical traditions as well), I mean all the modes of the major pentatonic scale, which is anhemitonic (scales that do not contain semitones) and can be considered as generated from a chain of fifths.
The reason why I am interested in this is that pentatonic can technically describe any 5-note scale, and I would like to be able to specify this Western pentatonic scale in a similar manner to how one specifies "the heptatonic scale" as "the diatonic scale".
However, I wouldn't be surprised if no such term, besides "modes of the major/minor pentatonic scale" or "Western pentatonic scale", existed, seeing as the meaning of diatonic is also sometimes vague.
