673387FCD351325AFF1CFB7AFF17A7A0.taxon	discussion	Remarks. Our male specimens are very similar to Duolandrevus (Duolandrevus) spinicauda Gorochov, 2016 from Sarawak and Duolandrevus (Duolandrevus) balikpapan Gorochov, 2016 from Kalimantan (both species from Borneo) in the general morphology. Our specimens show more similarities in the male FWs with D. spinicauda by the venation around the mirror area and its stridulatory file vein more sinuous; as well as more similar in the male genitalia with D. spinicauda by the pseudepiphallic lophi in profile almost not S-shaped (instead of clearly S-shaped in D. balikpapan) (these lobes in our specimens are also shorter like in D. balikpapan) and the pseudepiphallic paramere in profile view more rounded (distinct from both D. balikpapan and D. spinicauda). Our specimens are also more similar to the nominal subspecies in that the pseudepiphallic lophi curved dorsad only at the apex (instead of subapical part) and the pseudepiphallic parameres in profile more triangular (instead of flattened). Our specimens are, however, more similar to D. (D.) spinicauda gading Gorochov, 2017 in the metanotal gland having its lateral parts of posterior keel-like fold extended more posteriorly and laterally than the nominal subspecies. These suggest that the subspecies status require revision, and more material and additional data type will be necessary.	en	Tan, Ming Kai, Damit, Dayang Fazrinah Binti Awg, Japir, Razy, Chung, Arthur Y.

The calling song consists of an echeme made up of an average of 24 ± 1 syllables (21 – 27 syllables). The average echeme duration is 0.34 ± 0.03 s (0.29 – 0.40 s). The first few syllables are of lower amplitudes but eventually the amplitude increases to a maximum and remains relatively consistent. The average syllable duration is of 11.1 ± 0.6 ms (9.8 – 11.8 ms), the interval between consecutive syllables is 3.2 ± 0.4 ms (2.5 – 3.9 ms) and the average period is 14.3 ± 0.6 ms (13.3 – 15.0 ms). The frequency spectrum is pure-tonal and forms a harmonic series, with the energy peaking at a dominant and fundamental frequency of 3.66 ± 0.19 kHz (3.47 – 3.84 kHz).	en	Tan, Ming Kai, Damit, Dayang Fazrinah Binti Awg, Japir, Razy, Chung, Arthur Y.

Calling song (1 ♂, in captivity, 28.7 ° C) (Fig. 10). The calling song consists of an echeme with a highly variable number of isolated syllables, ranging from 10 to 68. Consequently, the echeme duration can be variable, ranging from 0.51 – 3.53 s. On average, the echeme duration is 1.25 ± 0.76 s and the average number of syllables is 24 ± 14. The first few syllables sometimes are of slightly lower amplitudes or of shorter durations, but these parameters eventually remain relatively consistent. Each syllable has an average duration of 16.1 ± 4.6 ms (9.8 – 22.0 ms), the interval between consecutive syllables is 38.9 ± 5.9 ms (29.8 – 46.6 ms) and the average period is 55.0 ± 2.8 ms (51.0 – 61.8 ms).

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.	en	Tan, Ming Kai, Damit, Dayang Fazrinah Binti Awg, Japir, Razy, Chung, Arthur Y.
