Extended distribution Kurixalus lenquanensis is currently known from south-eastern Yunnan (Mengzi, Gejiu, Wenshan) and central eastern Yunnan (Shilin), China. This species was found on shrubs in a fruit garden at Lengquan Villiage in Mengzi, shrubs near Yangjiatian Reservoir in Gejiu and shrubs at Yigebai Villiage in Wenshan (Fig. 3). However, differing from the habitats of this species in south-eastern Yunnan, in Shilin, the species was found in a sink hole (Fig. 3) away from farmland during the extremely dry season in 2023. The cave is about 100 m in vertical depth and the environment inside it is moist. Vegetation was rich at the entrance of the cave, but no vegetation and water were inside the cave. Probably the cave acts as a refuge of K. lenquanensis during the dry season because of the moist environment inside it.
