Abstract

Examination of the holotype of Hynobius stejnegeri Dunn, 1923 revealed that the species is identical with H. yatsui Oyama, 1947, recently resurrected from H. naevius (Temminck and Schlegel, 1838). The name H. yatsui is therefore relegated to a subjective junior synonym of H. stejnegeri. The latter name, however, has been widely applied to an amber-colored or tortoise-shell salamander from Kyushu, southwestern Japan, which now requires a new name. We, thus, describe the ambercolored salamander as a new species Hynobius ikioi. The new species is phylogenetically very close to H. amakusaensis Nishikawa and Matsui, 2014 and H. osumiensis Nishikawa and Matsui, 2014, both also from Kyushu, but is easily distinguished from them by its uniquely bi-colored dorsum.
