Plazi
Among this material there are at least three forms which differ clearly in song pattern from the previously described ones and from each other. Their songs differ mainly in three parameters, in echeme repetition rate (echeme period), in syllable repetition rate (syllable period) and in the number of syllables per echeme. For comparison, we present also data on the song of the Chinese species M. confracta ( Tab. 4 ). Concerning the structure of the stridulatory file,all species of the subgroup are relatively similar( Figs.11H–K , 12 ).
discussion · Plazi
According to Liu Cx et al. (2020), the species of this group „have mediate-width long tegmina, comparatively short files and the narrowest mirror. The file is widest in basal quarter, from which teeth are gradually narrower toward both ends. The songs are discontinuous and each song unit consists of numerous simple syllables“. The authors included the two newly described species Mecopoda confracta and M. synconfracta sp. n. ( China ), but listed also Mecopoda _“S” ( Malaysia ) with song and file data and Mecopoda _ “N” (Bali) ( Sismondo 1990 ) as group members. In addition and based on file structure, they added an unidentified Mecopoda species from Vietnam and an otherwise undescribed ‚ Mecopoda elongata‘ from India . From song structure also the „chirper“ in Nityananda & Balakrishnan (2006) belongs to the group. In our material specimens with a ratio larger than 1.5 (length/width of mirror area) always belonged to the confracta subgroup.
etymology · Plazi
Etymology. The species name indicates that its song consists of broken chirps.
diagnosis · Plazi
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 ).

Diagnosis. The species group “b” category has mediate-width long tegmina, comparatively short files ( Fig. 5 g–k) and the narrowest mirror ( Fig. 6 g–k). The file is widest in basal quarter, from which teeth are gradually narrower toward both ends ( Fig. 5 g–k). The songs are discontinuous and each song unit consists of numerous simple syllables ( Figs 2a, f, k ). Included taxa. Mecopoda confracta sp. n. ( China ), M. synconfracta sp. n. ( China ), Mecopoda _“S” ( Figs 3 k–o, 5i, 6i; Malaysia ) ( Sismondo1990 ), Mecopoda sp. ( Figs 5j , 6j ; Vietnam ), Mecopoda elongata elongata ( Figs 5k , 6k ; India ), and Mecopoda _“N” (Bali) ( Sismondo1990 ).
