Diagnosis. The new species is distinguished from its congeners by basal teeth of the stridulatory file which are abruptly becoming smaller proximad (Fig. 5g).

Bioacoustics. The song unit is only a simple chirp, made up of a few simple syllables (Fig. 2 a–d) (see song parameters in Table 3). Its song is very similar to the song type “Chirper“ that was described by Nityananda & Balakrishnan (2006), but different from the latter by the short interval between neighboring chirps. The relation between duration and period is 1: 2 in M. confracta sp. n. compared to 1: 4 in “Chirper”.

The species “b1” is widely distributed in southern China (including Yunnan, Guangxi, and Guangdong).

Etymology. The species name indicates that its song consists of broken chirps.
