RESUMEN
Penaeid shrimps are widely distributed from Indian to western Pacific Oceans and some which are economically important. In this study, we reported full mitochondrial genome of an endemic shrimp species, Penaeus acehensis, which inhabits exclusively in the coastal water of Aceh, Indonesia. Full length of circular mitogenome of P. acehensis was 15,991 bp in length, which contained 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and a control region. Start codons of all protein-coding genes were ATN except for COX1 in which ACG was used. Incomplete stop codon (T- -) was found in five genes including COX2, COX3, NAD5, NAD4, and NAD4L. Among its relatives, P. acehensis was most closely related to Penaeus monodon showing 89% sequence identity in its mitogenome, which was corresponding to morphological analysis. Phylogenetic tree result showed that P. acehensis was clustered together with those were distributed in Indo-West Pacific region (clade II), which is distinct from Eastern Pacific region (clade I).
