We applied next-generation sequencing (NGS) method to construct the complete mitochondrial genome of Glossogobius aureus. The obtained mitogenome of G. aureus (16,590 bp) exhibited a typical structure harboring 13 protein-coding genes (PCGs), 22 transfer RNAs (tRNAs), two ribosomal RNAs (rRNAs), and one control regions (D-loop). Most of mitochondrial genes are encoded on the heavy (H) strand, except for eight tRNAs and ND6. Unusual start codons were identified in COX1 (GTG) and ATP6 (TTG). Six genes (ND2, COX2, COX3, ND3, ND4, and CytB) were terminated by an incomplete stop codon (TA-/T-). A phylogenetic study showed that Glossogobius formed a clade distinct from other species in the subfamily Gobiinae. G. aureus was most closely related to G. giuris with 87.04% sequence identity among the four species in the genus Glossogobius.
