Remarks. Based on new material, we are able to redescribe the species and describe its calling song. The species is characterized by variation of melanisation, some specimens being almost black, while others are redbrown. Similarities in details of colouration, male genitalia and FW venation led us to consider these differences as intraspecific variation. New diagnosis. Cardiodactylus nigris is most similar to Cardiodactylus pictus in terms of general habitus and small size, colouration pattern and male FW venation and the pseudepiphallus having a posterior apex rectangular. However C. nigris shows the following distinctive characters: (1) the general colouration is more contrasted, dark orange brown to almost black, with a few yellow parts, including a narrow yellow band on lateral field of FWs; (2) the fastigium is yellow and the face has a darker shade of brown (fastigium dark brown and face yellow in C. pictus ) (3) the pronotum dorsal disk has a broader pair of cream-coloured longitudinal bands, (4) the pseudepiphallic parameres with their posterior and anterior lobes of equal size (instead of the anterior one distinctly broader and stouter than the posterior one), (5) the endophallic sclerite is very small and almost not extended anteriorly.

Distribution. Northern New Guinea , including Yapen I. and Biak I. Calling song ( Fig. 14 ). The calling of C. nigris song is composed of short echemes lasting 1.07±0.1 s. Each echeme is made up of 87±6 syllables. The average syllable duration is 5.0±0.3 ms and the syllable period is 7.2±0.1 ms. The frequency spectrum is made up of harmonics, the dominant frequency is 17.90±0.12 kHz, does not correspond to the fundamental harmonic, but to the third harmonic. The fundamental frequency is 6 kHz. The calling song activity seems to be more intensive during the night. On average, the call length and the number of echemes per call are higher during the night than the day (148.97±56.87 s vs. 83.08 ± 39.09 s and 15±5 echemes vs. 9±4 echemes, respectively).
