Characterization of the complete mitochondrial genome of Lysmata debelius (Decapoda: Hippolytidae)

Despite its wide distribution in the Indo–Pacific region and its popularity as an aquarium species, genetic studies on Lysmata debelius remain very limited. In this study, we obtained and characterized the complete mitochondrial genome (mitogenome) of L. debelius. Results showed that the mitogenome was 16,757 bp in length and consisted of 37 genes, including 13 protein-coding genes (PCGs), 22 transfer RNA genes, and two ribosomal RNA genes. Fourteen genes were light-strand encoded and 23 genes were heavy-strand encoded. The A + T content of the heavy strand was 67.16%. All PCGs had ATN as the start codon. Eight PCGs terminated with a complete stop codon of TAN, and five PCGs (ND3, ND5, ND4, Cox2, and Cytb) had an incomplete stop codon. The phylogeny of 42 shrimp species showed that all three Lysmata species were clustered together. The newly described mitogenome should provide valuable data for phylogenetic analysis of Hippolytidae.
