Diagnosis. The new species is distinguished from M. confracta sp. nov. by the spacing of the teeth of the stridulatory file, of which the basal teeth are gradually becoming smaller proximad (Fig. 5h).

Bioacoustics (see song parameters in Table 3). For its song type, a song unit is made up of several different-amplitude subunits. One subunit consists of 2 simple syllables. The neighboring subunits are broken (Figs 2 f–i). This new species is widely distributed in southern China (including Yunnan, Guangxi, Guangdong, and Hainan).

Etymology. The species name indicates its song unit consists of a series of chirps.
