Repapa trusmadi Gorochov, 2016: 73 View in CoL .

New material examined. EAST MALAYSIA; Sabah State • 1♂; Bukit Hampuan; N5.99629 E116.67598, 943.1± 11.5 m.a.s.l.; 4 November 2023, 21h00; calling under bark of fallen log; coll. M.K. Tan et al.; SBH.23.152 ( ZRC) GoogleMaps • 1♂; Tenompok Forest Reserve ; N6.01856 E116.50286, 1390.0± 6.6 m.a.s.l.; 6 November 2023, 19h59; calling under rotten log; coll. M.K. Tan et al.; SBH.23.187 ( ZRC) GoogleMaps .

Remarks. Our specimens from Bukit Hampuan and Tenompok Forest Reserve resemble the ones described by Gorochov (2016) in the male FW venations and metanotal gland. There are some slight variations in the apex of the pseudepiphallic lophi of the male genitalia, but the specimens still resemble R. trusmadi most, compared to other congeners and particularly Repapa brevipes (Chopard, 1937) from northern Palawan Islands. Owing to the close proximity of our specimens to Mount Trus Madi ( type locality), we refrain from considering the variations in the male genitalia as specific differences and refrain from describing a new species until we have more material.

Distribution. EAST MALAYSIA: Sabah State: Mount Trus Madi ( type locality), Crocker Range, Bukit Hampuan [new locality record], Tenompok Forest Reserve [new locality record].

Calling song ( 2♂, in the field, 21.1°C) ( Fig. 12 View FIGURE 12 ). The calling song consists of an echeme made up of an average of 17±1 syllables (15–18 syllables). The average echeme duration is 0.85± 0.05 s (0.76– 0.92 s). The average interval between consecutive echemes is 1.27± 0.39 s (0.87– 2.12 s). The very first few syllables are of slightly lower amplitudes but generally the amplitudes of syllables remain relatively consistent. The average syllable duration of 25.9±1.0 ms (24.1–27.7 ms), the interval between consecutive syllables is 26.1±0.9 ms (24.6–27.6 ms) and the average period is 52.0±0.5 ms (51.2–53.1 ms). The frequency spectrum is pure-tonal and forms a harmonic series, with the energy peaking at a dominant and fundamental frequency of 4.09±0.09 kHz (4.03–4.22 kHz).
