Odorrana utsunomiyaorum (Matsui, 1994)
Kogata Hanasakigaeru, Utsunomiya's Tip-nosed Frog
Individuals have a dorsal color ranging from light brown to greenish brown. The dorsum is scattered with numerous tubercles, while the side of the trunk is coarsely granular and the chest and abdomen are smooth. There is a weak, interrupted dorsolateral fold, but there is no supratympanic fold.
This species is the smallest of the R. narina group. Snout to vent length is 40-48 mm in males and 46-58 mm in females. Although R. utsunomiyaorum occupies the same range as R. supranarina, R. utsunomiyaorum is smaller with shorter hind legs. Also, the dark bars on the limbs are usually incomplete and irregular in R. utsunomiyaorum, unlike other frogs of the R. narina group.
