Neoxolmis Explained

Neoxolmis is a genus of South American birds in the tyrant flycatcher family Tyrannidae.

Taxonomy

The genus Neoxolmis was introduced in 1927 by the Austrian ornithologist Carl Eduard Hellmayr with the chocolate-vented tyrant as the type species.^[1] The genus name combines the Ancient Greek neos meaning "new" with the genus Xolmis that was introduced by Friedrich Boie in 1826.^[2]

This genus formerly contained only the chocolate-vented tyrant. Following the publication of a molecular phylogenetic study in 2020, three species were moved from the genus Xolmis to Neoxolmis.^{[3] [4] [5]}

The genus contains four species:^[5]
