The new species can be distinguished from all other congeners by a suite of morphological characters, including a dorsal-fin origin posterior to the pelvic-fin origin, a degenerated posterior chamber of the swim bladder, and an incomplete lateral line, with 11\u201313 lateral-line pores. Phylogenetic analysis based on mitochondrial cytochrome <jats:italic>b<\/jats:italic> (<jats:italic>Cytb<\/jats:italic>) gene sequences confirmed its separation, with uncorrected <jats:italic>p<\/jats:italic>-distances ranging from 1.4% to 8.7% compared to closely related species.
