Taxonomy
    
The genus Tanygnathus was introduced by the German naturalist Johann Wagler in 1832.[1] The type species was subsequently designated as the great-billed parrot (Tanygnathus megalorynchos) by the English zoologist George Robert Gray in 1840.[2][3] The name Tanygnathus combines the Ancient Greek words tanuō "to stretch out" and gnathos "jaw".[4]
The genus contains five species:[5]
- Great-billed parrot, Tanygnathus megalorynchos
 - Blue-naped parrot, Tanygnathus lucionensis
 - Blue-backed parrot, Tanygnathus everetti
 - Black-lored parrot, Tanygnathus gramineus
 - Azure-rumped parrot, Tanygnathus sumatranus
 
Genetic analysis has supported reclassifying all 4 species under Psittacula, making Tanygnathus a synonym of the former genus.[6]
