Phylogeny of the genus lagocephalus fishes(tetraodontiformes: tetraodontidae) from Korea

The Genus Lagocephalus fishes were caught to study the morphological, osteological and interrelationship in the coast of Pusan, Pohang, Kyungju and Cheju-do in Korea from September, 1989 to September, 1993. Five species representing Lagocephalus in Korea redescribed to species were provided. Cluster analysis method was used for the various morphological and osteological characters to clarify the interrelationship of the species level of genera, Lagocephalus. Lagocephalus inermis was classified into subgroup Ⅰ, and L. laevigatus, L. lunaris, L. gloveri, and L. wheeleri as subgroup Ⅱ at the level of 1.25 of average taxonomic distance. Lagocephalus inermis differs from the other four congeneric species, since it shows different synapomorphic characters of the frontal, pterotic, black gill slits, and prickles.
