Parapyrrhicia longipodex new species

( Figs 4 B, 4D, 4E, 4H)

Material examined. Holotype ♂. Madagascar, Ambanja ( NHMP).

Description. Male ( Figs 4 B, 4D, 4E, 4H). Green with a small blackish spot on the stridulatory area. Fastigium of vertex very narrow, just furrowed, not distinct from fastigium of frons, eyes round oval, prominent, fronto-genal keels absent. Antennae incomplete in the holotype. Pronotum longer than high ( Fig. 4 B), anterior margin straight, posterior rounded. Fore coxae armed with a small spine, fore femora with 4 small spines ventrally, fore tibiae with open tympana on both sides, superiorly rounded, with 5 inner and outer ventral spines + 1 spur on each side; mid femora with 3 ventral outer spines, mid tibiae with 13 inner and outer ventral spines + 1 spur on each side, 3 inner dorsal + 1 spur; hind femora with 9 inner and 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 very long, pointed and down-curved; supra-anal plate hidden below the last tergite ( Figs 4 D, 4H). Cerci stout, incurved, shorter than the last tergite, with a black chitinous inner not pointed spine before the apex ( Fig. 4 E). Subgenital plate very long and narrow, divided into two apically convergent lobes ( Fig. 4 H).

Female. Unknown.

Diagnosis. Parapyrrhicia longipodex is characterized by its long subgenital plate, last tergite and cerci. The absence of any black spot on the fore margin of tegmina and the different number of spines on hind femora allow to exclude that it may be the male of P. dentipes , of which only the female is known (black spots on the fore base of fore margin of tegmina, 10 outer and 3 inner ventral spines on hind femora: Saussure 1899). Differences from P. virilis may be noticed in the Fig. 4 .

Etymology. From Latin: longipodex (= with long anus) refers to the long subgenital plate.

Measurements. Male. Body length: 20.0; length of pronotum: 4.2; height of pronotum 2.7; length of tegmina: 26.6; width of tegmina: 4.2; length of hind femora: 19.0.
