Diagnostic remarks. One of the largest katydids in Mozambique, this slender insect can be identified by its elongate body, narrowly conical and hypognathous head, slender and spiny legs, and a distinct white line running along the sides of the body ( Figs. 22A, D View FIGURE 22 ). Its coloration varies from light green to brown. From its relative Clonia wahlbergi Stål, 1855   it can be distinguished by the shortened, black and yellow-bordered hind wings ( Fig. 22E View FIGURE 22 ), and the shape of the head ( Fig. 22C View FIGURE 22 ) and cerci ( Fig. 22B View FIGURE 22 ).

Bioacoustics. Males call at night from tall clumps of grass, producing a long, uninterrupted train of short syllables at the rate of 15–23 syllables/s (at 26°C), each syllable contains a short impulse created by the tegmina opening and a longer group of impulses produced by the tegmina closing; mean syllable duration is 0.05147 (SD=0.08954, n=89); the peak frequency of the call is 14.6–16.9 kHz ( Figs. 50 View FIGURE 50 A–C). The call is audible to the human ear from a few meters as a very soft buzz.

Distribution and natural history. P. macrocephala   , originally described from an unknown location in Mozambique ( Schaum 1853), has also been recorded from Zimbabwe, and Botswana ( Kaltenbach 1971). In Mozambique its presence has been confirmed so far only in the Sofala Province.

This species occurs in savanna and open woodland habitats, where it can be found in tall clumps of grass and small bushes. It is a nocturnal species that specializes in hunting flying insects. The prey is caught with the first two pairs of legs while the katydid hangs upside down from grass stems or a branch, attached only with its hind legs. Despite their slender appearance these katydids are powerful hunters, capable of catching and overpowering such large, strong fliers as hawk moths ( Sphingidae   ) and fruit-piercing moths ( Sphingomorpha   Guinée). In Gorongosa   adults can be found only during the wet season, between December and early May.
