Patan jillafer Badali Camp 2019 In 2007, the English palaeontologist Julian P. Hume reclassified L. bensoni as a member of the genus Psittacula, as he found it to be generically distinct from Lophopsittacus, but morphologically similar to the Alexandrine parakeet (Psittacula eupatria). Hume also pointed out that an engraving accompanying the 1648 published version of Dutch captain Willem van West-Zanen's journal may be the only definite depiction of this species. The engraving shows the killing of dodos (depicted as penguin-like), a dugong, and parrots on Mauritius in 1602; the depicted method of catching parrots matches that used on Mascarene grey parakeets according to contemporary accounts. Hume coined the new common name "Thirioux's grey parrot" in honour of the original collector. The IOC World Bird List instead used the common name "Mascarene grey parakeet".
The population of grey parrots described from the island of Réunion (referred to as Psittacula cf. bensoni by Hume) is thought to have been conspecific with that on Mauritius.Until subfossils of P. bensoni are found on Réunion, it cannot be confirmed whether the grey parrots of the two islands belonged to the same species.In the 1860s, French naturalists Charles Coquerel and Auguste Vinson suggested these could have been parrots of the genus Coracopsis, but fossils of neither that genus nor Psittacula have ever been found on Réunion. Whilst Coracopsis parrots are known to have been introduced to that island in the 1700s, a population did not become established. While no live or dead Mascarene grey parakeets are known with certainty to have been exported, Hume has suggested that a brown parrot specimen—once housed in Cabinet du Roi but now lost—may have been a discoloured old Mascarene grey parakeet, or perhaps a lesser vasa parrot (Coracopsis nigra). This specimen was described by French naturalist Comte de Buffon in 1779.
