The abundant clouded salamander from western Japan, Hynobius nebulosus, has long been considered a single widespread species, although some authors have suggested the inclusion of several cryptic species. This led to a molecular and morphological analysis of populations from all parts of the known range. Phylogenetic relationships were inferred from complete sequences of the mitochondrial cytochrome b gene, and nuclear genome differentiations were estimated by multiplexed inter simple sequence repeat genotyping by sequencing (MIG-seq). The results suggest that H. nebulosus hitherto recognized consists of at least nine species. We applied existing names to two of them, H. nebulosus (Temminck et Schlegel) and H. vandenburghi Dunn, and described seven others as new species.

Using mitochondrial DNA sequences, we surveyed genetic features of 12 individuals of Cynops pyrrhogaster introduced into Hachijojima Island, in order to estimate their possible origin in the main islands of Japan. The phylogenetic analysis revealed that the 12 examined newts of the introduced population display no genetic diversity and share characteristics with the conspecific population of Shikoku and thus belong to the WESTERN Clade proposed by earlier studies. Our results suggest that the Hachijojima population, having experienced a drastic founder effect, stems from very few individuals from the Shikoku District approximately 650 km to the west.
