Pitilla; type depository: Academy of Natural Sciences, Philadelphia – holotype male <i>Diagnostic description.—</i> Very similar to the previous species. Body slender, small for the genus; wings in both sexes surpassing apices of hind femora by about half their length (Fig. 37 B). Fastigium of vertex evenly tapered, its apex narrowly rounded, about as long as eye diameter and as wide as scapus (Fig. 23 F). Face flat, smooth; genal carinae of head poorly developed, hardly discernible. Dorsal surface of pronotum relatively rugose, flat; anterior margin of pronotum straight, posterior one weakly convex (Fig. 23 G); lateral lobes of pronotum about 1.7 times longer than high, their posterior angles right. Male stridulatory file straight, 1.2 mm long, 130 μm wide, with 239 closely spaced and relatively very wide, lamelliform teeth; teeth in proximal half of file thinner and more closely arranged than in distal part (Fig. 50 A); mirror approximately rectangular, slightly longer than wide; secondary veinlet next to AA1 well developed and forming actual margin of mirror; stridulatory area of left wing devoid of secondary venation, distal margin of left mirror convex; secondary veinlet next to AA1 present, somewhat divergent from AA1. Male 10th tergite with two short, rounded, usually more or less parallel lobes (Fig. 22 B); female 10th tergite with deep, narrowly triangular incision. Male cercus robust, somewhat inflated, with large, blunt, hook-like dorsal spine; apex of cercus constricted (Figs. 22 B-C). Female cercus simple, elongately conical, distinctly curved. Titillators flattened, squamose, distinctly dilated apically, apices multidentate, divergent (Fig. 23 A). Male subgenital plate with distinct ventral keel and deep triangular incision apically; female subgenital plate broadly triangular, with small, semicircular incision at apex. Ovipositor relatively slender, with distinct lamella along midline of upper valvula; ratio ovipositor/hind femur 0.61-0.67. <i>Coloration</i>.— General coloration light green (Fig. 37 B). Face pale green, mandibles brightly emerald green, labrum dark brown. Tegmina green, with contrastingly yellow venation. Legs green; abdomen light green; ovipositor light brown, with darker apex. <i>Measurements</i>.— Table 15. <i>Distribution</i>.— This species seems to have a wide distribution, ranging from Mexico, through Costa Rica (Map 14), to Panama. <i>Material examined.—</i> <b>COSTA RICA: Guanacaste Prov.</b>, Estac.
