Integrative Taxonomy Of The Genus Barbodes (Cyprinidae) In Peninsular Malaysia With A Focus On The B. Binotatus Species Complex And B. Lateristriga Morphotypes

This study focused on the fish genus Barbodes Bleeker, 1859 in Peninsular Malaysia, where four species have been often reported in the literatures, B. binotatus, B. banksi, B. lateristriga and B. dunckeri. Preliminary observations on the Barbodes fishes in Peninsular Malaysia had found variation in...

This study aims to resolve the taxonomic status of B. binotatus species complex and B. lateristriga morphotypes by morphology and molecular approach and provide a comprehensive species list of genus Barbodes in Peninsular Malaysia.
