About Rana uenoi Matsui, 2014
Males of Rana uenoi are smaller than females. Males reach approximately 5–6.2 cm (2.0–2.4 in) in snout-vent length (SVL), while females reach approximately 6–7.6 cm (2.4–3.0 in) SVL. Their base coloration is brown, with striped legs and dark tympana, the sensory structures located at the temple region of the head. Individuals sometimes have black dots on their back. The abdomen is white, and it becomes yellowish closer to the posterior end. Many small morphological features distinguish R. uenoi from Dybowski's frog; for example, R. uenoi has longer hindlimbs. This species occurs in wooded habitats across the Korean Peninsula and its neighboring islands. While it is very likely present in North Korea, conclusive evidence confirming this occurrence is incomplete. It is also found on Tsushima Island, Japan.
