Abstract:
Tephrinectes sinensis, an endemic flatfish from China's coastal waters, has remained taxonomically contentious owing to its distinctive morphology and osteology. We sequenced and annotated the first complete mitochondrial genome of this species using Illumina HiSeq 2500. The circular mitogenome spans 17,366 bp, encoding 13 protein-coding genes (PCGs), 22 tRNA genes, two rRNA genes, and a control region. A maximum-likelihood phylogeny places T. sinensis as a single-taxon lineage sister to the remaining Paralichthyidae. This matrilineal pattern is congruent with the long-standing morphological debate over its familial placement.The complete mitogenome provides a foundational genomic resource for resolving relationships within Pleuronectiformes.
