Description
Subgroup confracta Liu, 2020
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.
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).
