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

The snapping shrimp <i>Alpheus digitalis</i> 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 <i>A. digitalis</i>, 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 <i>A. digitalis</i> and <i>Alpheus hoplocheles</i>. These findings furnish essential mitogenomic resources for advancing phylogenomic, taxonomic, and evolutionary investigations of caridean shrimps.
