ABSTRACT=<p>The complete mitochondrial genome of <italic>Eleutheronema rhadinum</italic> was determined for the first time. The <italic>E</italic>. <italic>rhadinum</italic> mitogenome was 16,718 bp in length, comprising 13 protein coding genes (PCGs), 2 ribosomal RNAs (rRNAs), 22 transfer RNAs (tRNAs), 1 control region (CR), and 1 L-strand replication origin (O<sub>L</sub>). The genome organization, and base composition were similar to other teleosts. An additional non-coding region detected in the HSL cluster, was with significant similarity to the nearby tRNA-Leu (CUN), which could be a useful marker for identifying <italic>E. rhadinum</italic> and <italic>Eleutheronema tetradactylum</italic>. Furthermore, phylogenetic analysis showed species in the family Polynemidae were well clustered together. But sister relationships between Polynemidae and Sciaenidae, Menidae plus Lactariidae were refused by present study.</p>
