text: The closest relatives are not the other species that occur in the East Pacific, but rather Panulirus argus from the Caribbean Sea and West Pacific species such as Panulirus japonicus, Panulirus marginatus, Panulirus pascuensis, Panulirus cygnus and Panulirus longipes; this relationship has been recovered from comparative studies of adult and larval morphology, as well as from molecular phylogenetics, using the sequences from cytochrome c oxidase and 16S ribosomal RNA genes.
