Range extension of Spanner barbs, Barbodes lateristriga (Valenciennes, 1842) (Cypriniformes: Cyprinidae) to Bangka Island, Indonesia

The Spanner barb, Barbodes lateristriga, a Cyprinid, lives as a benthopelagic in the clear mountain streams with rocks and boulders beds, frequently found below waterfalls. This species was previously recorded from Southern Thailand; Malay Peninsula, Singapore and Borneo. In this study, we report from Bangka Island, Indonesia. The Bangka Islands are located on the Sundaland, which has a quite high biodiversity. The specimens of B. lateristriga were taken from the Menumbing Hill River, Bangka Island, Indonesia and then identified morphologically and molecularly. The molecular identification was carried out using the DNA barcoding method and the standardized cytochrome c oxidase subunit I (COI) gene. The results of molecular analysis revealed that specimens of the Bangka Islands are B. lateristriga with a similarity level of up to 100%. This is also confirmed by the results of phylogenetic tree analysis where samples from the Bangka Islands clustered in the same group as B. lateristriga found in the Genbank.
