Description. Male. General habitus & colour. Small-sized species, green with some darker spots on the posterior margin of tegmina; typical are whitish oblique veinlets ( Figs. 25a View FIGURE 25 ). Head and antennae. Antennae thin. Fastigium of vertex about 1.5 times as wide as scapus of antenna ( Figs. 25b, 25c View FIGURE 25 ); fastigium verticis meeting equally broad fastigium of frons along a horizontal line; face with evident frontogenal carinae; eyes elongate and oval ( Fig. 25c View FIGURE 25 ). Thorax. Pronotum as long as high, with evident lateral carinae, flat and smooth disc, anterior margin broadly incurved, posterior margin rounded ( Figs. 25b, 25d View FIGURE 25 ). Wings. Both pairs of wings fully developed; tegmina rounded at tips, narrow, 4.5 times longer as broad. Stridulatory file arched, consisting of ca. 80 evenly spaced teeth ( Fig. 25f View FIGURE 25 ). Legs. Fore coxa unarmed. Fore femora dorsally unarmed, ventrally with 3 spines. Mid femora with 2 ventral spines. Hind femora with 3 ventral outer and inner spines. Fore tibiae with an open tympanum on both sides, dorsal margin rounded ( Fig. 25e View FIGURE 25 ), with a ventral double row of 4 spines; mid tibiae with ventral double row of 6 spines. Hind tibiae with double row of 12 spines on ventral side and many on dorsal side; 3 slender sclerotized spurs on each side. Abdomen. Last abdominal tergite unmodified, ending with two imperceptible lateral tips, between them the margin is concave. Cerci are stout, apically narrowing and incurved with a pointed tip. Subgenital plate is straight with two small apical tips, similar to styli ( Figs. 26c, 26d View FIGURE 26 ).

Female. Same characteristics of the male, but tegmina are 3.8–3.9 times longer as broad, ovipositor short, subgenital plate triangularly pointed, with two lateral basal bulges ( Figs. 26a, 26b View FIGURE 26 ).

Measurements (mm). Males. Body length: 14.5–15.0; pronotum length: 3.1–3.2; pronotum height: 3.1–3.2; length of tegmina: 22.6–23.8; width of tegmina: 4.9–5.2; length of hind femur: 12.5–12.7. Females. Body length: 14.2–16.0; pronotum length: 3.1–3.2; pronotum height: 3.1–3.2; length of tegmina: 21.2–24.9; width of tegmina: 6.0–6.5; length of hind femur: 12.0–14.0; ovipositor: 4.9–5.1.

Diagnosis. Pseudoeurycorypha civilettorum gen. and sp. n. is very characteristic for the absence of a spine on the fore coxae, the rounded dorsal margin of the fore tibiae, and the pronotum as long as it is high.

Distribution. Known from Dzanga-Ndoki National Park ( Central African Republic), Nouabalé-Ndoki National Park ( Republic of Congo) and Taï National Park ( Côte d’Ivoire).

Etymology. Pseudoeurycorypha civilettorum gen. and sp. n. is dedicated to my late mother Emanuela ‘Nela’ Civiletti (1912–1961) and her paternal family, which also included the famous sculptor Benedetto Civiletti (1845– 1899).

Remarks. Following the key provided by Chopard (1954), among the species with open tympana lacking the spine on the fore coxae Pseudoeurycorypha civilettorum n. sp. results in being recovered near the genus Bueacola Sj ̂stedt, 1912, which contains only one species ( B. cornigera from Cameroon). However, Pseudoeurycorypha civilettorum n. sp. has very peculiar pronotal and frontogenal carinae and elongate eyes similar to those of the species of the genus Eurycorypha . Presently it seems difficult to establish the tribe to which the genera Bueacola and Pseudoeurycorypha may belong, but very likely they are related to Amblycoryphini , despite the absence of the spine on the fore coxae.
