The Cuban grassquit was formally described in 1789 by the German naturalist Johann Friedrich Gmelin under the binomial nameLoxia canora.[2] He based his description on the "Brown Cheeked Grosbeak" that had been described by Peter Brown in 1776. Brown's illustration was from a live bird belonging to Marmaduke Tunstall which Brown mistakenly believed had come from Mexico. It only occurs in Cuba.[3][4] This species was formerly placed in the genus Tiaris,[4] but a molecular phylogenetic study published in 2014 found that Tiaris was polyphyletic.[5] In the resulting reorganization, the Cuban grassquit was moved to the resurrected genus Phonipara that had been introduced in 1850 by the French naturalist Charles Lucien Bonaparte.[6][7][8] The genus name combines the Ancient Greekphōnēs meaning "vocal" with the Latinparus meaning "tit". The specific epithet conora is from Latin canorus meaning "melodious".[9] The Cuban grassquit is monotypic: no subspecies are recognised.[8]
Although traditionally placed with the buntings and New World sparrows in the family Emberizidae,[4] molecular genetic studies have shown that the Cuban grassquit is a member of the subfamily Coerebinae within the tanager family Thraupidae.[7]
