 Early writers claimed the Mascarene parrot was found on Madagascar , an idea that led French naturalist and ornithologist René Primevère Lesson to coin the junior synonym Mascarinus madagascariensis in 1831 . His new genus name prevailed and , when Tommaso Salvadori combined it with the earlier specific name in 1891 , it became a tautonym ( a scientific name in which the two parts are identical ) . Lesson also included species of the Tanygnathus and Psittacula genera in Mascarinus , but this was not accepted by other writers . The following year , German herpetologist Johann Georg Wagler erected the genus Coracopsis for the Mascarene parrot ( which became Coracopsis <unk> under this system ) and the lesser vasa parrot ( Coracopsis nigra ) . English zoologist William Alexander Forbes , believing that mascarinus was invalid as a specific name , since it was identical to the genus name , coined the new name Mascarinus <unk> in 1879 , in honour of Dubois . The binomial name was emended from M. mascarinus to M. mascarin in 2014 .
