| occurrence of two types of hynobius naevius in northern kyushu, japan (amphibia: urodela). | a survey to examine genetic variation among hynobius naevius from four localities of fukuoka pref., northern kyushu, japan, resulted in the detection of two, sympatric, genetic types (a and b) that are clearly different in the allelic frequencies of four loci (acoh-a, acoh-b, adh-a, and sod-a) in each locality. morphological investigations between the two genetic types also proved that they are clearly discriminated; the type a is about 75 mm in svl, lacks mottling pattern on bluish purple dorsu ... | 2003 | 14709811 |
| morphological discrimination of two genetic groups of a japanese salamander, hynobius naevius (amphibia, caudata). | hynobius naevius, distributed on western honshu, shikoku, and kyushu islands of japan, includes two genetically distinct groups (groups a and b) that have never been delimited morphologically. using specimens from the entire species range, we investigated the possibility of distinguishing these groups morphologically. multivariate analyses of morphometric characters resulted in recognition of two groups that corresponded well to the two genetic groups. one (group a) was characterized by larger b ... | 2005 | 16357472 |
| estimation of the type locality of hynobius naevius (temminck and schlegel, 1838), a salamander from japan (amphibia: caudata). | a small japanese salamander, hynobius naevius, long considered a single species, has recently proven to include two groups (group a=large type and group b=small type) that are split at the species level. we compared the type series of h. naevius with specimens of the two groups to clarify which of them corresponds to true h. naevius, and to estimate the type locality of this species, which was not given in detail in its original description. results of various morphological analyses altogether i ... | 2007 | 17961000 |
| two new species of lotic breeding salamanders (amphibia, caudata, hynobiidae) from western japan. | two new species of lotic-breeding salamanders, hynobius sematonotos and h. oyamai, are described from chugoku district and northeastern kyushu district, respectively, western japan. they are members of the so-called h. naevius group and are phylogenetically close to h. naevius, h. katoi, and h. hirosei but divergent from them with large genetic distances. these new species have been treated as chugoku and northeastern kyushu lineages, respectively, of h. naevius to which they are morphologically ... | 2019 | 30790830 |
| taxonomic status of a salamander species allied to hynobius naevius and a reevaluation of hynobius naevius yatsui (amphibia, caudata). | a japanese small salamander, hynobius naevius (temminck and schlegel, 1838), has recently proven to include two species (larger [a] and smaller [b]) that are reproductively isolated and are genetically and morphologically distinct from each other. of these two species, species a is considered to correspond to true h. naevius. to determine the name of species b, we investigated five specimens stored at kyushu university and concluded from the locality and date of collection that they represent sy ... | 2008 | 18275239 |
| phylogenetic relationships of hynobius naevius (amphibia: caudata) as revealed by mitochondrial 12s and 16s rrna genes. | using mitochondrial 12s and 16s rrna sequences, we investigated phylogenetic relationships among populations of the endemic japanese salamander hynobius naevius. monophyly of this species was recovered only in the maximum parsimony tree and was unresolved in maximum likelihood and bayesian trees. instead the following four haplotype clades consistently emerged clearly: clade 1 from northwestern kyushu, clade 2 from chugoku and northeastern kyushu, clade 3 from western shikoku and kyushu, and cla ... | 2006 | 16337138 |
