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
) and a distinctly shorter tegmen in comparison to the length of the hind wing (
Fig.
25I
).
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
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.
