Diagnostic description.— Body large, with wings in both sexes extending well beyond apex of abdomen ( Fig. 6 A). Fastigium of vertex forming large horn, with conspicuous, round dilatation below apex, apex sharply pointed; fastigium about 5 times as long as eye diameter; dorsal part of fastigium granulose ( Fig. 6 B-C). Face convex; genal carinae of head well developed, granulose. Pronotum smooth, shiny; metazona slightly raised; anterior dorsal margin straight, posterior one convex; lateral lobe of pronotum 1.8 times longer than high. Male stridulatory file nearly straight, 2.1 mm long, 156 μm wide, with 206 closely spaced, wide, lamelliform teeth ( Fig. 43 A); mirror approximately rectangular but with sides somewhat convex; small, parallel vein next to AA 1 present.

Ventral spines of femora long, conical, usually contrastingly white; all genicular lobes armed with long, sharp spines. Male cercus thick, blunt, and somewhat incurved, slightly thicker at apex than at base; ventral, subapical spine of cercus short and thick ( Figs. 6 D-E). Female cercus simple, elongately conical, somewhat curved. Male subgenital plate only weakly narrowed toward apex, apex with shallow incision; styli short, about twice as long as wide ( Fig. 6 E). Female subgenital plate approximately triangular, with small apical incision.

Ovipositor long, straight, less than twice as long as hind femur (ratio ovipositor/hind femur 1.7) ( Fig. 6 A).

Coloration.— General coloration green. Fastigium of vertex yellow, its dilated apical portion reddish brown; face green, clypeus, labrum and outer parts of mandibles yellow; inner parts of mandibles black. Pronotum green, with a contrasting red, hourglass-shaped pattern, continuous with red stripe on the head and fastigium of vertex. Tegmina green, densely mottled with brown dots; posterior margin of tegmina purple-red, resulting in conspicuous dorsal stripe when wings are folded; male stridulatory file usually bright white. Legs green, with white femoral spines. Abdomen green.

Measurements.— Table 4 .

Bioacoustics.— Call unknown.

Distribution.— In Costa Rica C. cochleata is known only from the Osa Peninsula ( Map 5 ). It also occurs in Panama (Chiriquí). Another, undescribed species of Copiphora with a similar, spoon-shaped fastigium of vertex occurs in Coclé Province, Panama.

Material examined.— COSTA RICA: Puntarenas Prov., Península de Osa, 2.5 mi SW Rincón, 08°42’N, 83°29’W, March 1973 (coll. Chadab) – 1 male; Península de Osa, Estac. Esquinas , elev. 200 m, 15 September 1993 (coll. M. Segura) - 1 female ( INBio); PANAMA: Chiriquí, (coll. Staudinger) - 1 female (allolectotype) ( NHMW); same locality, 1 - 30 April 1878 - 1 male (lectotype) ( NHMW).
