Description

Hynobius takedai has a snout to vent length of 52-67 mm and a total length of 98-124 mm. It usually has 12 costal grooves. Its limbs are relatively short and when the forelimb and the hindlimb are adpressed to the flank, there is a space of 0.5-2 costal grooves between the tips of the toes. Its dorsal color is dark to yellowish brown and females generally have black blotches.

H. takedai was described as a distinct species by Matsui and Miyazaki (1984). The shallow U-shape of its vomerine teeth, its slightly longer limbs, and its relatively stable number of costal grooves distinguish it from the similar species H. abei (Goris and Maeda 2004).

The takedai in the scientific name is a patronymic. The "Hokuriku" in the vernacular refers to an area of northwestern Honshu comprising of the prefectures of Ishikawa, Fukui, Niigata, and Toyama (Goris and Maeda 2004). [3684]
