The reconstruction of evolution phylogeny of lobster species are necessary for revealing stock identity that can be used for the management of fisheries industries in Iran. Phylogenetic relationships among lobster species, from Oman Sea, Persian Gulf were examined with nucleotide sequence data from cytochrome oxidase subunit I (COI). The previous works on phylogeny showed that the mitochondrial COI gene in crustacean is a good discriminative marker at both inter- and intra-specific levels. For this purpose, DNA extraction using phenol- chloroform method (HILLIS and MORITZ, 1990) was done. The evolutionary relationships among these species of the lobster were examined using 610 bp of mitochondrial (mt) DNA from the cytochrome oxidase subunit I gene. The result completely agrees with the previously defined species using morphological characters. The resulted phylogenetic trees supported the monophyly of these species. The results imply that Iran's species’ origin is Indo-west pacific. Iran's species, which were grouped with the other Lobster taxa seem to always form a sister clade with Indo-west pacific species with bootstrap support of around 80%.
