Calling song ( Fig. 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).

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 ). Our specimens also resemble Tapiena bullata Karny, 1923 from Malay Peninsula, particularly in the shape of the apex of their cercus.

Remarks. Our specimen resembles most Tapiena incisa Karny, 1923 previously described from Sarawak , particularly by the shape of the male cercus ( Fig. 33C ). However, our male specimen also differs in an important character: the male tenth abdominal tergite is truncated excised in the middle (and not triangularly excised) ( Fig. 33D ). This species is also similar to Tapiena paraincisa Tan & Wahab, 2018 from Brunei Darussalam (not too far from Mount Trus Madi) by its stout body, red (or purple) fore femora and tympanal area ( Fig. 32 ) and stridulatory areas on both tegmina ( Figs 33A, 33B ), but also differs distinctly by the cercus at its apex broad and flattened (instead of tapering into two tooth-like processes) ( Fig. 33C ), the tenth abdominal tergite being broadly and truncated and excised in middle (instead of narrowly excised) ( Fig. 33D ) and the subgenital plate having much shorter apical lobes but longer styli ( Fig. 33E ) (see also Tan & Wahab, 2018a ). Based on new material from Sabah , it appears that Tan et al . (2019) may have misidentified the Tapiena reported in Lungmanis (near Lahad Datu in Sabah ).
