Morphological comparisons with 15 congeneric species, including members of the <jats:italic>S. sihama<\/jats:italic> complex, show that <jats:italic>S. persica<\/jats:italic> closely resembles <jats:italic>S. sihama<\/jats:italic> in meristic counts and coloration but is clearly distinguished by a unique swim bladder morphology. The posterior sub-extensions of the anterolateral swim bladder extensions in <jats:italic>S. persica<\/jats:italic> display a complex structure comprising five broad extensions connected to the swim bladder body, a feature absent in <jats:italic>S. sihama<\/jats:italic> and other sillaginids. Additional diagnostic characters include distinct meristic, morphometric, and coloration traits. Molecular analyses of mitochondrial cytochrome c oxidase subunit I (COI) sequences corroborate this species\u2019 distinctiveness, with phylogenetic reconstruction placing <jats:italic>S. persica<\/jats:italic> haplotypes and a previously recognized G5 clade haplotype of the <jats:italic>S. sihama<\/jats:italic> complex in a strongly supported monophyletic clade sister to <jats:italic>S. indica<\/jats:italic> and <jats:italic>S. suezensis.<\/jats:italic> Intraspecific genetic divergence within haplotypes of silaginid species and clades of <jats:italic>S. sihma<\/jats:italic> ranged from 0.00 to 0.01 (K2P). The <jats:italic>S. persica<\/jats:italic> haplotypes matched the G5 clade of <jats:italic>S. sihama<\/jats:italic> (0.01, K2P distance) whereas it exhibited 0.18\u20130.24 K2P divergence from haplotypes of other sillaginid species and clades of the <jats:italic>S. sihama<\/jats:italic> complex.
