Song.
Continuous sequence of syllables, perceived only in the immediate surrounding, produced in the afternoon hours.
Altitudinal range at Mt Kilimanjaro
: 1300–1400–
1700–1900 m
Remarks.
Montane species with a slightly different dorsal aspect of the stridulatory rib as given by Bailey (1975). Studies on the song have to be undertaken to bring light into this
complex
of montane-bound species. The species is flightless with shortened tegmina and reduced alae. Bailey (1975) stated that
Ruspolia
species in montanous areas of Africa probably reveal a common phylogenetic stock and have become isolated at their respective highland localities. Species similar to
R. exigua
are the West African species
R. brevipennis
(Chopard)
and
R. jaegeri
(Roy)
and the south-west African distributed species
R. sarae
Bailey.
