The complete mitochondrial genome of <i>Alpheus digitalis</i> De Haan, 1844 (Decapoda: Alpheidae)

The snapping shrimp Alpheus digitalis De Haan, 1844 represents a commercially valuable fishery resource within the family Alpheidae. In this study, we sequenced and characterized the complete mitochondrial genome of A. digitalis, followed by phylogenetic reconstruction to elucidate its evolutionary relationships. The genome is 15,735 bp in length and contains 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), 2 ribosomal RNA genes (rRNAs), and 1 D-Loop control regions, with a pronounced A + T bias (60.66%). Phylogenetic analysis based on 13 PCGs robustly supports a sister-group relationship between A. digitalis and Alpheus hoplocheles. These findings furnish essential mitogenomic resources for advancing phylogenomic, taxonomic, and evolutionary investigations of caridean shrimps.
