Rana longicrus is a medium-sized frog, with a maximum SVL of 55 mm; females are larger than males. The snout is pointed in lateral view and acute in dorsal view. R. longicrus has a long narrow body with slender limbs. Fingers and toes are rounded, but do not have enlarged tips. The skin has a smooth texture with indistinct small black bumps (Lue 1990).

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).
