Comment

In the Hynobius nebulosus group by implication. Matsui, Nishikawa, Tanabe, and Misawa, 2001, Comp. Biochem. Physiol. B—Comp. Biochem., 130: 181-189, documented that populations of the type locality of Hynobius tokyoensis are more closely related to Hynobius lichenatus than to other populations of "Hynobius tokyoensis" from the Nagoya Region, which are more closely related to Hynobius nebulosus. Thorn and Raffaëlli, 2000, Salamand. Ancien Monde: 51-52, provided a brief account. Goris and Maeda, 2004, Guide Amph. Rept. Japan: 3234, provided an account, map, and photograph. See brief account by Raffaëlli, 2007, Les Urodèles du Monde: 47-48. Ogano, Kasahara, Yagi, Tanaka, and Yoshino, 2007, Bull. Herpetol. Soc. Japan, 2007: 9-14, discussed the range and population status in Chiba Prefecture. Matsui, Tominaga, Hayashi, Misawa, and Tanabe, 2007, Mol. Phylogenet. Evol., 44: 204-207, reported on phylogeography and suggested that Hynobius tokyoensis is the sister taxon of Hynobius nebulosus and together the sister taxon of Hynobius lichenatus. See photograph, map, description of geographic range and habitat, and conservation status in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 552. Raffaëlli, 2013, Urodeles du Monde, 2nd ed.: 70, provided a brief account, photo, and map.
