A new locality was reported for Esomus metallicus in Kapalo Banda River, 50 Kota Regency, West Sumatra Province, Indonesia, about 74 km from Maninjau Lake. Identification of species was made by morphological and molecular methods using the COI gene. We also applied the Neighbor-Joining method to construct the phylogenetic tree. Based on morphological analysis, the specimens from Kapalo Banda River were E. metalicus with the unique feature of having long maxillary barbels. Based on the DNA sequence, specimens of West Sumatra were identical to E. metallicus sequence of Thailand specimens with a similarity of 99-100%, suggesting the probable origination of the Kapalo Banda River from Thailand.
