The complete mitochondrial genome of Microdous chalmersi (Gobiiformes: Odontobutidae)

Microdous chalmersi is an Odontobutidae fish that mainly inhabits in East and Southeast Asia. In this study, the complete mitochondrial genome of M. chalmersi was first determined and described. It was 16,485 bp in length and composed by 13 protein-coding genes, 22 tRNA genes, two rRNA genes, a putative light strand origin of replication (O-L) and a putative control region (D-loop). The overall nucleotide composition was 28.9% of A, 16.0% of G, 25.0% of T, and 30.1% of C, with a total of 53.9% A + T content. Phylogenetic analysis suggested that M. chalmersi had the closest evolutionary relationship with Micropercops swinhonis. The availability of the M. chalmersi mitogenome would contribute to further phylogenetic research of Odontobutidae and genetics studies of this species.
