Diagnostic remarks.
Similar to
P. graminea
but the male cerci strongly bent inwards in the apical half and not narrowly tapered (
Fig. 44A
). Males frequently have a dark brown spot on the stridulatory area of the left tegmen (
Fig. 44C
). Both green and yellow forms of this species are known, the latter sometimes with brown, irregular spots on the dorsal (posterior) half of the tegmina (
Fig. 44B
).
Bioacoustics.
The call of
P. satiscaerulea
is very similar to that of
P. graminea
and consists of 2–3 syllabic echemes produced every 6–9s; mean syllable duration is
0.043 s
(SD=0.0113, n=19); the peak frequency of the call is 9.3–12.3 kHz (
Figs. 53
J–L). The call is audible from a distance of a few meters.
Distribution and natural history.
P. satiscaerulea
was recently described from
Tanzania
but this species appears to have a much wider distribution. In
Mozambique
it has so far been only recorded in
Gorongosa
, where adults can be found throughout the year.
Females have a wide, relatively long ovipositor with a broadly rounded apex (
Fig. 44D
), adapted to laying eggs between the layers of the leaf epidermis (
Fig. 44E
).
