Males 3.5-5.2 cm in length, females 4.9-6.1 cm. The width and length of the head are roughly the same. The snout is short and pointed. There are dark, vertical markings on its lips. The tympanum and temporal fold are visible. It has various coloration, with a dark v-shaped horizontal mark between the eyes. The irregular longitudinal folds on the back are its most distinguishing feature. Males have a single, subgular vocal sac with a division at the center that makes it look like a pair. The male’s vocal sac is partially black. It is most often seen in rice fields, grass swamps and other still waters. It makes continuous “guo-guo-guo” alls. (Photo courtesy of Peng Zhen-ru)
