Female Rana longicrus are bright red, while males are yellow or brown. On the head, black stripes are present near the eyes. Lips are black with white spots all over. On the dorsum, black spots form the shape of the Chinese character for "eight". Front and hind legs have crossbars (Lue 1990).
The tadpole of Rana longicrus has a rounded body, small mouthparts, and a high tail fin. Two black spots are visible on the dorsum (Kuramoto et al. 1984).
