The Leptodea leptodon (Bivalvia: Unionidae) is native to the United States, it is threatened by human activities and habitat destruction. In the present study, it’s complete mitochondrial genome was reconstructed from whole-genome Illumina sequencing data with an average coverage of 1213X. The total length of mitogenome is 16,133 bp, which consists of 37 typical animal mitochondrial genes, including 22 transfer RNAs (tRNAs), 13 protein-coding genes (PCGs) and two ribosomal RNAs. The putative control region (329 bp) is located between ND5 and tRNA-Gln, with an A + T content of 67.4 %. The base composition of the genome is A (38.7 %), C (26.7 %), G (10.8 %) and C (26.7 %) with an overall GC content of 37.5 %. Phylogenetic analysis suggests that L. leptodon is closely related to its confamilial counterparts than to the other taxa.
