Abstract

The genus Hiatella is one of most abundant and widespread marine bivalves. To date, its intra-generic phylogeny remains disputed and mitogenome information is therefore much needed. Here, we first report the complete circular mitogenome of Hiatella sp. J that is distributed in the coast of Asia Pacific. The total length of this mitochondrial genome is 21,233 base pairs. It consists of 13 protein-coding genes, 22 transfer RNAs, 2 ribosomal RNAs, and a major noncoding region (MNR). Phylogenetic analysis of COI from 25 species (Hiatellidae) revealed that the Hiatella sp. J was closely related to Asian Hiatella in the family Hiatellidae. This Hiatella mitogenome provides new molecular data for the further taxonomic and phylogenetic studies of the genus Hiatella of marine bivalves.
