( Figs. 44 View FIGURE 44 A–E, 53J–L)

Diagnostic remarks. Similar to P. graminea but the male cerci strongly bent inwards in the apical half and not narrowly tapered ( Fig. 44A View FIGURE 44 ). Males frequently have a dark brown spot on the stridulatory area of the left tegmen ( Fig. 44C View FIGURE 44 ). 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 View FIGURE 44 ).

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 View FIGURE 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 View FIGURE 44 ), adapted to laying eggs between the layers of the leaf epidermis ( Fig. 44E View FIGURE 44 ).

Measurements (3 males, 2 females). body w/wings: male 43.3–43.8 (43.5.3), female 44.2–44.8 (44.5.4); body w/o wings: male 21.4–23.8 (22.21.4), female 27.2–29.7 (28.51.8); pronotum: male 6.5–6.6 (6.5.1), female 6.8–7 (6.9.1); tegmen: male 33.5–35.4 (34.51), female 37–38.4 (37.71); hind femur: male 14.9–17.1 (15.91.1), female 16.8–17.4 (17.1.4); ovipositor: 6.8–7.6 (7.2.6) mm.
