Material examined. CAR. Dzanga-Sangha SR, 2.VI.1998, Bayanga-Lidjombo pk15, P. Annoyer (1♂ holo- type) ( PAPC) .

Diagnosis. Paraeurycorypha ocellata n. sp. is characterized by eye elongated as in Eurycorypha . Pronotum dorsal margins are rounded, tympanum of fore tibia is open, fore femora are laterally compressed, mirror of right tegmen is present, styli are present.

Description. Male ( Fig. 27 ). General habitus and colour. Tegmina yellowish with scattered large blackish spots, some surrounding a small yellow spot, like eyespots ( Fig. 27 ). Abdomen yellow, legs yellow and black ( Figs. 28–31 ). Head. Fastigium of vertex not contiguous with fastigium of frons, wider than first antennal segment. Eyes elliptical, prominent, face smooth ( Fig. 30 ). Thorax. Pronotum as long as high, with rounded margins, surface shiny with a well-developed humeral excision on the lateral lobes ( Figs. 30, 32 ). Anterior margin of pronotum incurved, posterior margin rounded, pronotum lobes widely rounded. Tegmina with a net of veinlets; anterior margin of tegmina rounded. Stridulatory area marked ( Fig. 32 ), right tegmina with mirror ( Fig. 32 ), stridulatory file short, ca. 0.5 mm long, consisting of about 50 arched teeth ( Fig. 35 ). Legs. Short, fore coxae armed with a fine spine, open tympana on inner and on outer fore tibiae, that are furrowed dorsally. Ventral inner margin of fore femora armed with 4 spines, ventral outer margin of mid femora armed, ventral outer and inner margins of hind femora armed with 10 spines, genicular lobes of hind femora armed with 1 spine on inner and outer margins. Fore tibiae ventrally armed with 4 spines + 1 long apical spur on outer and inner margins, mid tibiae armed on outer and inner margins, hind tibiae with many spines on ventral and dorsal margins + 3 apical spurs on each side. Abdomen. Cerci stout at the base, with a robust apical inward spine ( Figs. 33–34 ). Subgenital plate much longer than wide, ending with two styli ( Fig. 33 ).

Measurements (mm). Male. Body length: 18.0; length of pronotum: 6.0; height of pronotum: 4.0; length of fore femora: 4.5; length of hind femora: 22.5; length of tegmina: 30.0; width of tegmina: 10.0.

Etymology. From Latin ocellatus = bearing eyespots, after the presence of eyespots on tegmina.
