    Abstract:
    To identify lobster phyllosoma larvae of the genus Panulirus occurring in waters adjacent to Japan, genetic variation within and between 10 Indo-Pacific lobster species was investigated using restriction fragment length polymorphism (RFLP) analysis for the 1300-base pair mitochondrial cytochrome oxidase I (COI) gene. RFLP analysis using two endonucleases (AluI and TaqI) enabled discrimination of all species, including the P. longipes complex. The diagnostic DNA markers, supplemented with nucleotide sequence analysis, were applied to 44 mid- to late-stage phyllosoma larvae (7.4 to 27.7 mm in body length) collected in the northwestern Pacific. These samples were unexpectedly variable in species composition, comprising P. japonicus (n = 16), P. longipes bispinosus (21), P. longipes longipes (1), P. "aka" (1), and P. penicillatus (5). Comparison of larval size at similar stages revealed that P. l. bispinosus larvae were significantly larger than P. japonicus.
