Other material: Male CH7704, SOUTH EAST ASIA, exact locality unknown, obtained from breeder, 2013 (song, stridulatory organs, chromosomes). Males CH3751, CH 3645, CH3739, MALAYSIA: Selangor, Ulu Gombak Field Study Centre (20 km nno Kuala Lumpur) (3°20’N, 101°45’E), 260 m, 12–19 iv 1981 and 28 ii–24 iv 1984, leg. K.-G. Heller & M. Volleth. Six pairs of male tegmina CH3656, CH 3663, CH3666, CH 3687, CH3688, CH 3690 from the same locality GoogleMaps   .

The song of the species is described by Sismondo (1990) ( SINGAPORE; as species S), by Korsunoskaya (2008) ( INDONESIA: Sumatra) and by Hartbauer et al. (2006; 2012) ( MALAYSIA).

Diagnosis. The species has a much slower echeme repetition rate than the other species of the subgroup (echeme periods about 3 s; Tab. 4 View TABLE 4 ).

Description. Morphologically no difference to other species of the M. confracta   subgroup (Liu Cx et al. 2020).

Measurements (in mm): CH 3738, 3746: pronotum length 8.0–8.7; tegmen length 55–57; tegmen width 13; hind femora length 42.0–44.5.

In peninsular Malaysia, the species is often found syntopically with M. himalaya   (our data, Tan & Kamaruddin 2016). It is typically a little bit smaller than himalaya   and often brown, whereas himalaya   is more often green.

Chromosomes: 2n = 29, FN = 52; pairs 1 metacentric and 4–7, 9, 10, 12–14 metacentric/ submetacentric, 3 subacrocentric, 2, 8 and 11 acrocentric, X chromosome submetacentric ( Fig. 15 View FIGURE 15 ).

Derivatio nominis. Named in honour of Enrico Sismondo who discovered the song diversity of Mecopoda   , collected and recorded the type specimens of M. sismondoi   and analyzed and described the signal interactions in that genus ( Sismondo 1990).
