title: Molecular phylogeny of Japanese Catocala moths based on nucleotide sequences of the mitochondrial ND5 gene.
abstract: Phylogenetic relationships of 31 Japanese Catocala species were analyzed based on the partial nucleotide sequences of the mitochondrial NADH dehydrogenase subunit 5 (ND5) gene (762 bp). When several non-Catocala Noctuidae moths were designated as the outgroup, these Catocala species formed a monophyletic group. However, divergences between these Catocala species were very deep, and no close phylogenetic relationships were recognized among them except for that between the two recently separated species, C. xarippe and C. fulminea. The remote relationships implied for several pairs of species suggest that the color of the hindwings is a changeable characteristic, and does not reflect phylogenetic lineage. Continental specimens were analyzed in 20 of 31 Catocala species, and all of them showed a close relationship with their Japanese counterpart. However, the closeness of the nucleotide sequences between the Japanese and continental individuals of the same species varied from species to species, indicating that isolation between the Japanese and continental populations of these species occurred at many different times. The two analyzed species endemic to North America showed a close relationship with their morphologically inferred Japanese counterparts, indicating that the geographic separation and following speciation between these Eurasian and American species occurred much more recently compared with the speciation events among the Catocala species now found in Japan.
