W Madre de Dios); type depository: Academy of Natural Sciences, Philadelphia – holotype male <i>Diagnostic description.—</i> General characteristics as described above; wings in both sexes barely reaching apices of hind femora (Fig. 36 F). Fastigium of vertex 2.5 times as long as eye diameter, narrowly rounded apically, with distinct dorsal furrow dorsally; ventral keel of fastigium distinctly undulant (Figs. 35 D, 35G). Male stridulatory file nearly straight, 0.95 mm long, 111 μm wide, with 209 closely spaced and relatively very wide teeth (Fig. 51 D); stridulatory area on male without secondary venation; mirror square; secondary veinlet next to AA1 present, thick, divergent from AA1. Ventral anterior spines of hind femora nearly twice as long as width of hind femur below knee, distinctly flattened (Fig. 35 L). Tenth tergite of male with two somewhat divergent, wide lobes; female 10th tergite with lobes somewhat narrower, pointed; male cercus straight, basal internal spine curved towards base, slightly inflated subapically and distinctly constricted apically (Fig. 34 D); female cercus simple, elongately conical, somewhat curved. Male titillators needle-like, strongly bent (Fig. 34 E). Ovipositor short, sickle-shaped, about as long as half of hind femur (ratio ovipositor/hind femur 0.53-0.61). <i>Coloration</i>.— General coloration light green (Fig. 36 F); face creamy white; fastigium reddish-brown; clypeus and mandibles dark purple; metazona of pronotum in male with large, white, round spot; surrounded with dark brown margin; venation of tegmina and posterior edge of tegmina contrastingly yellow. <i>Measurements</i>.— Table 27. <i>Distribution.—</i> This species is known from only a few records in northeastern Atlantic portion of the country (Map 18). <i>Material examined.—</i> <b>COSTA RICA: Cartago Prov.</b>, Monumento Nacional Guayabo, A.C.A.C.
