Sciaenidae is a diverse, commercially important family. To understand the phylogenetic position of Collichthys niveatus in this family, we present its complete mitochondrial genome sequence. The genome is 16469 bp in length and contains 37 mitochondrial genes (13 protein-coding genes, 2 ribosomal RNA genes and 22 transfer RNA genes) and a control region (CR) as in other bony fishes. Further sequencing for the complete control region was performed on Collichthys lucida. Although the conserved sequence domains such as extend termination associated sequence (ETAS) and conserved sequence block domains (CSB-1, CSB-2 and CSB-3) are recognized in the control region of the two congeneric species, the typical central conserved blocks (CSB-F, CSB-E and CSB-D) could not be detected, while they are found in Miichthys miiuy and Cynoscion acoupa of Sciaenidae and other Percoidei fishes. Phylogenetic analyses do not support the monophyly of Pseudosciaeniae, which is against with the morphological results. C. niveatus is most closely related to Larimichthys polyactis, and Collichthys and Larimichthys may be merged into one genus, based on the current datasets.
