Bioacoustics. Tegmina (Fig. 3), stridulatory file (Table 1), and spectrum of the song (Fig. 6) do not show large differences to the typical Hetrodini pattern. The calling song (Fig. 8C) consists of long series of syllables (song type B in Fig. 5) with varying duration (1–40 s measured). Surprisingly also in SRR relatively large differences were found (12–42 Hz), which may be at least partly explained by temperature differences during recording (18–26ºC).

Genitalia. The central part of the genitalic sclerites (titillator) of our specimen (Fig. 9C) is similar to that figured by Glenn (1991).

Chromosomes: 2n = 26 (24 + neo-XY), FN = 29; pairs 1 and 2 meta/submetacentric, 3–12 acrocentric, neo-X acrocentric and neo-Y meta/submetacentric (1 male); thin C-bands in the paracentromeric region in all chromosomes including the sex chromosomes, and thick telomeric C-positive blocks in three acrocentric medium-sized pairs 3, 4, 5 (Fig. 12C).
