Abstract
A new species of music frog, Nidirana guibeiensis sp. nov., is described from northern Guangxi, China. Based on two mtDNA fragments analyzed, phylogenetic trees reveal that N. guibeiensis sp. nov. is most closely related to N. leishanensis. However, the new species can be identified by conspicuous diagnostic morphological characteristics as well as bioacoustics. In contrast to the known Nidirana species, the advertisement calls of the new species can be divided into three types, calls with one, two, and three notes. In addition, the new species has nest construction behavior, which is inconsistent with N. leishanensis. Nidirana guibeiensis sp. nov. occurs in paddy fields or still pools at 300–1300 m a.s.l.

Nidirana guibeiensis Chen, Ye, Peng & Li, sp. nov.
Diagnosis: Nidirana guibeiensis sp. nov. differs from its congeners in the combination of the following characteristics: larger body size (SVL 50.2–63.6 mm in males; 54.6 mm in the only sampled female); dorsum smooth with tubercles on the posterior of the back; surfaces of throat, chest, and upper part of the belly with grey clouding, lower part of the belly near immaculate creamy white; dorsal midline with a discrete creamy-white line; lateroventral grooves present on all fingers and toes but not on Finger I; tibiotarsal articulation reaching the level between eye and nostril; a pair of subgular vocal sacs present; three types of calls: one note, two notes, or three notes.
Etymology: The species name refers to its distribution in northern Guangxi. ‘Guibei’ means northern Guangxi. We suggest the English name Guibei Music Frog and the Chinese name Gui Bei Qin Wa (桂北琴蛙).
