Allozymic variation of Hynobius kimurae Dunn (Amphibia, Caudata)

Cryptic species and systematics of the hynobiid salamanders of the Liua–Pseudohynobius complex: Molecular and phylogenetic perspectives

“…Molecular data have repeatedly revealed a surprisingly high amount of genetic divergence in morphologically conservative amphibian species that might otherwise be indistinguishable. These include hynobiid salamanders such as Hynobius and Batrachuperus, where allozyme and mitochondrial DNA sequence data have revealed several cryptic species (Matsui, 1987;Matsui et al, 2000).…”

Taxonomic Relationships of an Endangered Japanese Salamander Hynobius hidamontanus Matsui, 1987 with H. tenuis Nambu, 1991 (Amphibia: Caudata).

“…Relative distances from allozymic data, however, show a good taxonomic standard (Matsui, 2000b). Hynobius tenuis and H. hidamontanus are genetically not considered to be different species because their genetic distances are much smaller than are found among already named species or even within one species of Hynobius (D>0.22: e. g., Matsui 1987;Matsui et al 2000;Nishikawa et al 2001).…”

“…The geohistory of the Japanese islands including the formation of the Fossa Magna (=Itoigawa-Shizuoka tectonic line) was supposed to have strongly affected the formation of patterns in distribution and divergence of these animals (Matsui, 1987;Matsui et al, 2000;Nishikawa et al, 2001).…”

“…For studies of intra-and interspecific variations and taxonomy among morphologically similar urodelan species, electrophoretic studies contribute the best data (e. g., Matsui et al, 1992Matsui et al, , 2000Jackman and Wake, 1994;Highton, 1999). Indeed, recent genetic analyses by electrophoresis have elucidated many taxonomic problems in Hynobius (e. g., Matsui 1987;Nishikawa et al, 2001).…”

Population Structure of the Salamander Hynobius retardatus Inferred from a Partial Sequence of the Mitochondrial DNA Control Region

“…In recent decades, intraspecific phylogeny and population genetics studies have been conducted using various molecular markers in several species of the Japanese salamander genus Hynobius, including H. tokyoensis (Matsui et al, , 2007, H. kimurae (Matsui et al, 2000), H. boulengeri , H. naevius (Tominaga et al, 2003), H. nebulosus (Yamane and Nishida, 2010), H. yatsui (Sakamoto et al, 2009), and H. retardatus (Matsui et al, 1992a). This work is an extension of those studies.…”
