Comprehensive Description

Read full entry


Adults reach sizes of 71-73 mm snout-vent length and 121-133 mm total length. The trunk is fairly long and stocky. The tail is broad at the base and, when viewed from above, narrows to the tip. The limbs are long and robust as well. When the fore- and hindlimbs are adpressed, the toes of each overlap by the distance of one costal grove or more. There are 13, occasionally 14, costal groves. The hind feet have five toes. The dorsal color is reddish brown with sporadic yellowish spots from head to tail. The ventral color is light and without markings.

This is the only salamander in its range. It was once thought to be a subspecies of Hynobius naevius but is now recognized as a full species, as it was in the original description; its coloration is completely different from that of H. naevius.
