New material examined. EAST MALAYSIA; Sabah State • 2♂; Sinipung Hill, near Long Pasia and Meligan ; N4.44538 E115.71494, 1556.0± 10.1 m.a.s.l.; 21 November 2024, 21h30; attracted to light trap; coll. M.K. Tan; SBH.24.205, 206 ( ZRC) GoogleMaps • 2♂; Meligan (P28 a.k.a. pt 2); N4.57619 E115.73923, 1266.0± 6.8 m.a.s.l.; 23 November 2024, 22h00; attracted to light trap on the road; coll. M.K.

Remarks. Our specimens resemble those collected from Mount Trus Madi by Tan et al. (2024a) and northwestern Kinabalu ( Muhammad & Tan, 2025) in the important species characters, including the shapes of the male cercus, tenth abdominal tergite and subgenital plate, as well as the shape of the stridulatory areas ( Fig. 14 View FIGURE 14 ). Our specimens also resemble Tapiena bullata Karny, 1923 from Malay Peninsula, particularly in the shape of the apex of their cercus.

Type locality. EAST MALAYSIA: Sarawak: Baram River, Gunong Tamabo .

Calling song ( Fig. 15 View FIGURE 15 ). The calling song is an isolated echeme made up of an average of 11–12 closely-spaced syllables. The average echeme duration is 0.70± 0.10 s (0.58– 0.79 s). Within each echeme, the amplitudes of the syllables increase to a maximum; the average syllable duration is 13.7±1.4 ms (12.2–15.3 ms) and the average down time (silent interval between the two syllables) is 48.6±7.1 ms (40.7–54.5 ms). The average period of syllable is 62.3±5.8 ms (55.7–67.4 ms). The frequency spectrum is broadband and is not symmetrical and has a peak frequency of 13.82±0.83 kHz (13.41–14.16 kHz).
