Diagnostic remarks. One of the smallest katydids in Mozambique, P. parva   can be distinguished from other members of the genus by the shape of the male cerci ( Fig. 25H View FIGURE 25 ) and a distinctly shorter tegmen in comparison to the length of the hind wing ( Fig. 25I View FIGURE 25 ).

Bioacoustics. The call of P. sparsa   consists of a series of single syllables produced at the rate of approximately 0.2/s; mean syllable duration is 0.10966 s (SD=0.02159, n=6); the peak frequency of the call is 42.7–50.4 kHz ( Figs. 51 View FIGURE 51 G–I). This species is the only katydid in Gorongosa   other than Gorongosa carri   known to produce a purely ultrasonic call.

Distribution and natural history. P. parva   has so far been known only from its type specimens collected in Nigeria, the Democratic Republic of the Congo, and Malawi ( Ragge 1956a), and this is its first record from Mozambique. Based on the known distribution of this species it is likely that it occurs throughout the sub-Saharan Africa. In Gorongosa   P. parva   is a rarely encountered species, found in open, grassy habitats, where it has been seen feeding on flowers of grasses.

Measurements (1 male, 1 female). body w/wings: male 22.5, female 19; body w/o wings: male 9.6, female 9; pronotum: male 2.4, female 3; tegmen: male 10.7, female 12; hind femur: male 12.3, female 14; ovipositor: 4 mm.
