摘要A new species of Leptobrachella is described from Sichuan Province and Chongqing Municipality,China.Molecular phylogenetic analyses based on mitochondrial and nuclear gene sequences indicated that the new species is genetically divergent from its congeners.It could be identified from its congeners by a combination of followings characters:body size of male 29.1-34.1 mm(n = 14),female 34.1-34.9 mm(n= 4);dorsal skin rough with large tubercles in size of humeral glands,without conical spines;fringes on toes narrow;ventral body basically floral white with deep grey pigments all over;dorsal body deep greyish brown with smoky black markings;iris gold above,gradually silver bellow;tibia-tarsal articulation reaches the level of the middle of the eye when leg being stretched forward;the main call type with dominant frequency 4.08±0.16 kHz(14.1-14.9℃),call duration 170.35±15.19 ms,the number of pulses for the first note in a call 3.50±0.89,and the number of pulses for the second note in a call 5.08±0.77.
