Characters
. Only the male of
P. virilis
was shortly described and later this species has no more reported; for this reason peculiar characters of both sexes are here listed.
Male (
Figs 3
A, 4A, 4C, 4F, 4G). Green with a two small blackish areas at the base of tegmina and along their hind margin. Eyes round prominent. Pronotum longer than high, anterior margin straight, posterior rounded (
Fig. 4
A). Stridulatory file curved and constituted of ca. 100 evenly spaced teeth (
Fig. 3
A). Fore coxae armed, fore femora with 7 small spines ventrally, fore tibiae with open tympana on both sides, superiorly rounded (not forrowed), with 5 inner and outer ventral spines + 1 spur on each side; mid femora with 4 ventral outer spines, mid tibiae with 9 inner and outer ventral spines + 1 spur on each side; hind femora with 3 inner and 12 outer ventral spines, hind tibiae with many spines + 3 spurs on each side. All genicular lobes with a pair of small spines on each side. Last tergite long, pointed and down-curved (
Fig. 4
C). Cerci slender, long and incurved, flattened in the apical part (
Fig. 4
F). Subgenital plate narrow, ending with a wide concavity and two sulcate divergent lobes (
Fig. 4
G).
Female (
Figs 3
B, 3C, 3D). Same characters and colour of the male, with the following differences. Hind femora with 3 inner and 13 outer ventral spines. Ovipositor 2 times longer than pronotum, with upper and lower apices serrate (
Fig. 3
D). Subgenital plate small and triangular (
Fig. 3
B) [different from that of
P. dentipes
Saussure, 1899
and
P. madagassus
(Karsch, 1889)
]. In addition, the female has on inner margin and on the dorsal area of right tegmen some transverse and longitudinal veins with little teeth covered by very small bristles (
Fig. 3
C), that certainly are used for acoustical communication with the male. A similar character (one to three transverse veins) has been already highlighted by
Hemp
et al
. (2016)
in the female of
P. abdita
Hemp, 2016
. However, most females of
Phaneropterinae
have some teeth on the right tegmen to communicate with the other sex (
Heller
et al
. 2015
).
