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 series of echemes repeated at 0.6 Hz and with about 30 syllables each ( Fig. 8B ; see Table 2 ). The first echeme of a series is often slightly longer than the following.

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

Chromosomes: 2n = 29 (28 + X0), FN = 29; pairs 1–14 and X chromosome acrocentric (2 males); thick (occupied the region next to the centromere) C-bands in the paracentromeric region in the long/medium chromosomes and the X chromosome, thin C-block in the short-sized autosomes ( Fig. 12B )
