(Figs. 35 A–H, 55J–L)

Diagnostic remarks. A medium size green katydid (Figs. 35G, H), similar in its general characteristics to P. guytonae but easily identifiable by the unique, deeply branched structure of the male cercus (Figs. 35A, B) and strongly elongated posterior lobes of the subgenital plate (Fig. 35C). The stridulatory file is 1.7 mm long, with 97–109 teeth (Fig. 35D). The ovipositor in P. abdita is more slender and its upper valvula ends in a sharp point (Fig. 35F). The call of this species lacks the frequency modulation seen in P. guytonae.

Bioacoustics. The call of P. abdita is a series of syllables in groups of 2–4; mean syllable duration is 0.0033 s (SD=0.002105, n=20); the peak frequency varies from 18.2 to 24.6 kHz but exhibits no consistent incremental changes that are seen in P. guytonae (Fig. 55 J–L).

Distribution and natural history. P. abdita was recently described from Central Tanzania (Udzungwa Mountains National Park and Kihansi forest reserve) but its presence in Gorongosa indicates a much wider distribution. In Gorongosa this species is found in dense riparian forests and adults have only been seen at the end of the rainy season, in March and April.
