Year: 2025
Type: article
Abstract: The identity of Labeo nigrescens Day, 1870 is established based on examination of syntypes and a topotype from South Canara. L. nigrescens can be distinguished from congeners by its distinct colour pattern and a unique lateral line feature. A population from the Chalakkudy River basin in Kerala, formerly considered conspecific with L. nigrescens, is described here as Labeo chekida, a new species. In addition, a species from the Chandragiri River basin in Northern Kerala and South Canara, characterised by dramatically elongated finnage, is recognised as a new species distinct from L. nigrescens and L. filiferus and is described here as Labeo uru sp. nov.
