recent genetic evidence has found that the genus "psittacula" is likely paraphyletic; for example, genetic analysis has supported merging short-tailed parrots of the genus "tanygnathus," "psittinus," and the extinct "mascarinus" with "psittacula." an alternative classification system to this was proposed by braun "et al." (2019) that splits the genus "psittacula" into multiple monophyletic genera in order to preserve "tanygnathus, psittinus," and "mascarinus" as distinct genera. after the proposed split, the only remaining species in "psittacula sensu stricto" are "p. derbiana" and "p. alexandri". the list of split or monophyletic genera and species is displayed below:
