Xiangcheng Toothed Toad
The male is 49 mm long. The female is 57 mm long. This species has vertical pupils. No tympanum is visible. The upper maxillary teeth are relatively developed. The dorsum is full of thin and small spiny tubercles. Hind legs are short, with the tibiotarsal articulation extending only to the corner of the mouth. Toes are usually completely webbed, and outside of breeding season, the grooves are relatively deep. The dorsal surface is olive palm or palm brown, and completely lacks a dark piebald marking. The ventrum is light in color. The male has nuptial spines on the dorsal surfaces of the first and second finger and a pair of large, closely spaced, spiny clusters on the chest. Spines are thin and densely clustered.
Tadpoles are 60 mm in body length and 22 mm in head length. They are grayish brown or grayish palm. At the junction of the body and the tail there is a palm red “U” mark. The labial tooth row formula is I: 4-4/I:4-4. The center of the upper lip lacks three papillae. A few additional papillae are present at the corners of the mouth (Fei 1999).
Distribution and Habitat
Life History, Abundance, Activity, and Special Behaviors
In the morning, these toads hide under or between the large rocks by the streamside. At night, they will squat on the rocks by the water. Some will only expose their heads. Once disturbed, they quickly escape into the water.
Individual egg diameter is 3.8 mm. The animal pole is extremely palm brown in color. Tadpoles are commonly found in backwater pools by the streams, especially in shallow areas where water grasses grow (Fei 1999).
