Taxonomy & naming
Hamilton described the species in 1822 as Cyprinus boga, from the Brahmaputra at Goyalpara in Assam. It is now placed in Labeo, with the authority in parentheses. Labeo is a large genus of labeonine cyprinids with a ventral, fringed mouth used to scrape algae and detritus from hard surfaces, found in Africa and Asia.
