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.

Material examined (1 specimen). Mozambique: Sofala, Gorongosa , GNP, Bela Vista ranger outpost, elev. 26 m (-18.69470, 34.20853), 5–12.v.2015, coll. P. Naskrecki— 1 male ( MCZ) .
