Two overlooked generic synonyms in the Thraupidae (Aves: Passeriformes)

Area of Science:

• Ornithology
• Taxonomy
• Zoology

Background:

• A 2016 revision proposed the tanager genus Islerothraupis, with Tanagra cristata as its type species.
• This revision overlooked a prior genus-level type designation for Tanagra cristata.

Purpose of the Study:

• To identify and rectify an error in the recent generic classification of tanagers.
• To establish the correct taxonomic nomenclature for the genus containing Tanagra cristata.

Main Methods:

• Reviewed historical ornithological literature, specifically Jarocki's 1821 "Zoologiia."
• Examined the original description of the subgenus Loriotus and its type species designation.

Main Results:

• Identified that Feliks Pawel Jarocki designated Tanagra cristata as the type species for the subgenus Loriotus in 1821.
• The minimal description of Loriotus was provided in Polish, detailing bill morphology.

Conclusions:

• The genus Islerothraupis proposed by Burns et al. (2016) is invalid due to the earlier designation of Loriotus.
• Correct taxonomic classification requires acknowledging Jarocki's 1821 contribution to tanager nomenclature.
