Eurycorypha prasinata Stål 1874

Material examined. Madagascar, Morarano-Chrome forest (1♂) ; Madagascar, 25 km West Marontsetra 13.IV.1991, A. Pauly (1♂) ; Madagascar, Foulpointe I.1994, A. Pauly (1♀) ( RBINS) ; Madagascar, Antalaba (1♀) ( NHMP) .

Measurements. Males. Body length: 11.3–12.0; length of pronotum: 3.4–3.5; height of pronotum: 2.9–3.0; length hind femur: 11.1–12.1; length of hind tibia: 11.9–12.3; length of tegmina: 21.0–22.0; width of tegmina: 4.9– 5.1. Female. Body length: 14.8–15.2; length of pronotum: 3.8–4.2; height of pronotum: 3.9–4.0; length hind femur: 13.9–14.1; length of hind tibia: 15.0–15.8; length of tegmina: 24.5–26.7; width of tegmina: 6.0–8.4.

Remarks. Only the female of this species was known ( Stål 1874), characterized by the pronotum with rough punctuation. Karsch (1889) reported it from some continental African countries; however, it is supposed to be an endemic taxon from Madagascar and the description of the male has to be carried out from Madagascar material. The specimens above listed (both males and females) have rough punctuation on the pronotum and small black dots scattered on the tegmina and may be considered to belong to the same species, E. prasinata . It is possible to exclude E. brevipennis Karsch, 1889 from Madagascar, that also has a wrinkled pronotum with definite margins, but its tegmina are rather short and very oval, with the hind wings no longer than fore wings.

Characters of male. Anterior margin of pronotum concave, posterior margin rounded. 5 spines on inner margin of fore femora, 5 spines on inner ventral margin of fore tibiae, mid femora unarmed, mid tibiae with 7 spines on inner and outer ventral margins, hind femora with 8 spines on outer and 3 on inner ventral margins, hind tibia with 3 apical spurs on each side. Last tergite not modified, cerci incurved, stout with a black tip. Subgenital plate concave with very small styli.

Distribution. Madagascar and Comoro Is. ( Chopard 1958); the presence in continental Africa has to be confirmed.
