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 consists of a long, uninterrupted trill (song type A) with a SRR of about 28 Hz (Fig. 10E; see Table 2).

Genitalia. The titillator is relatively large and massive with short basal parts and a slightly bifurcate tip (Fig. 11A). The lateral sclerites are weakly developed.

Chro mosomes: 2n = 17 (16 + X0), FN = 28; pairs 1–5 meta/submetacentric, 6–8 acrocentric, X chromosome submetacentric (2 males); thin C-positive paracentromeric bands in all chromosomes and an interstitial one on the pair 2 (Fig. 12I).
