Ruspolia Schultess 1898

Ruspolia sp. “G4

(Figs. 11I, J, 47 J–L)

Diagnostic remarks. This species, known so far from a single male specimen, is readily identifiable by the strongly narrowed tegmina that are unlike any other Ruspolia species in Gorongosa (Fig. 11J). The stridulatory file is relatively long and narrow, with 107 teeth; the mirror is slightly angular, with comparatively thin posterior vein of the mirror (A 1 + A 2) (Fig. 11I).

Bioacoustics. The call is a slow trill, with syllables produced at the rate of 7.2/sec (at 26°C); mean syllable duration is 0.1019 (SD=0.00704, n=25), with the frequency peak at 10.5–11.1 kHz (Figs. 47 J–L). The call is loud and readily audible to the human ear.
