Figs 4A–4D View FIGURE 4

KarSch, 1889 (1888). Berlin Ent. Z. 32: 455.

Material examined. Cameroon, Mukonje Farm, R. Rohde (2♂, 3♀) ; Cameroon, Mt. Koupé 31.I–8.II.1983, J. van Stalle (1♂) ; Gabon, N’Toum 29.IX.1985 (light), A. Pauly (1♂) ( RBINS) .

Measurements. Males. Body length: 18.0–18.5; length of pronotum: 4.0–4.1; height of pronotum: 3.6–3.8; length hind femur: 11.8–12.1; length of hind tibia: 13.5–14.0; length of tegmina: 22.5–23.0; width of tegmina: 7.0– 7.4.

Characters of the male. The description of the male by Karsch (1891) is too short, further characters are below reported. Small species, fastigium of vertex wide, ca. 2 times as wide as scapus. Fronto-genal carinae welldeveloped. Antennae as long as body. Pronotum flat, with slightly concave anterior margin and rounded posterior margin. Lateral carinae distinct, humeral excision well-developed, integuments smooth. Tegmina about 3.0 times longer than broad, rounded at the tip; differently from most species of the genus Eurycorypha , second pairs of wings are nearly as long as tegmina. Stridulatory file 1.2 mm long, curved, with ca. 80 evenly spaced teeth, central higher than lateral ones ( Fig. 4A View FIGURE 4 ). 4 spines on inner ventral margin and 2 on outer ventral margin, fore and mid femurs without dorsal spines. Fore femur with 3 spines on inner ventral margin, mid femur with 4 outer ventral spines, hind femur with 9 spines on outer ventral margin and 3 on inner ventral margin. Hind tibia with 3 apical spurs on each side. Last abdominal tergite modified, enlarged and divided into two down-curved processes. Cerci up-curved, stout at their base with a fine black tip ( Figs 4B, 4C View FIGURE 4 ); before the tip a second ramification of cerci branches off: the main base of cerci is 1.7 mm long, while the second branch is 2.6 mm long, out-curved and finely tipped ( Figs 4B, 4C, 4D View FIGURE 4 ). Subgenital plate concave, long, without styli.

Distribution. Known from Kimpoko ( Zaire), Democratic Republic of Congo, Cameroon, Fernando Poo ( Guinea) ( Karsch 1889, 1890, 1891, Griffini 1906, 1908, Sjöstedt 1912) and here reported from Gabon.
