Rasbora arundinata is a species of ray-finned fish in the genus Rasbora . It inhabits the Tripa Jaya, Kluet, and Alas rivers in Sumatra. [2]
This species is native to the rivers of northwestern Sumatra. Specimens have been found in various habitats, including gravel-bottomed mountain streams, moderate-flowing turbid rivers, and muddy backwater pools. R. arundinata has been observed sympatrically with other Rasbora species such as R. api , R. kluetensis , and R. haru . [3]
R. arundinata is distinguished by a prominent black midlateral stripe that intensifies centrally, forming a wedge-shaped subdorsal blotch, collectively resembling a reed-leaf-like profile. The body is laterally fusiform, and the species exhibits typical cyprinid features.
The species is part of the sumatrana group within the Rasbora genus. The formal description of R. arundinata, along with its congeners, introduced a new diagnostic character for the group: the partial exposure of the upper lip due to a submedial contact between the maxilla and the lower lip, marked posteriorly by a lachrymal groove.
