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]
Habitat and distribution
[edit]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]
Morphological characteristics
[edit]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.
Taxonomy
[edit]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.
