Mecopoda sismondoi Heller sp. nov.

Holotype: male, labels: (1) Singapore [1°17′ N, 103°50′ E] 84 A, (2) Brit. Mus. 1985-242, (3) Molted to adult 28 I 84 gassed on 9 VI 84, (4) COLLECTED BY E. SISMONDO (5) SONG-RECORDED (6) The stridulation of this specimen has been recorded. Tape No. 568 Recording No 1, (7) NHMUK010210931. NHM. Song and stridulatory organs studied.

Paratypes; males CH 3746, MALAYSIA: Selangor, Ulu Gombak Field Study Centre (20 km nno Kuala Lumpur) (3°20’N, 101°45’E), 260 m, 8–28 iii 1981, leg. K.-G. Heller & M. Volleth (song and stridulatory organs). CH 3738, MALAYSIA: Selangor, Ulu Gombak Field Study Centre (20 km nno Kuala Lumpur) (3°20’N, 101°45’E), 260 m, 12–19 iv 1981, leg. K.-G. Heller & M. Volleth (song and stridulatory organs) (all CH).

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.

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).

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).

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).
