Diagnostic description.— General characteristics as described above. Male stridulatory file straight, 1.2 mm long, 153 μm wide, with 229 closely spaced and very wide, lamelliform teeth; teeth in proximal half of file thinner and more closely arranged than in distal part ( Fig. 49 E); mirror approximately rectangular, slightly longer than wide; secondary veinlet next to AA 1 well developed, strongly divergent from AA 1; stridulatory area of left wing devoid of secondary venation, distal margin of left mirror concave; secondary veinlet next to AA 1 present, strongly divergent from AA 1.

Male 10th tergite with two long, rounded, clearly divergent lobes ( Fig. 22 D). Male cercus relatively slender, cylindrical, with large, blunt, hook-like dorsal spine; apex of cercus finger-like ( Fig. 22 D-E). Female cercus simple, elongately conical, distinctly curved. Ttillators flattened, squamose, distinctly dilated subapically, apices multidentate, narrowed, strongly divergent ( Fig. 23 B). 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 file of pegs along midline of upper valvula ( Fig. 22 A); ratio ovipositor/hind femur 0.70-0.77.

Coloration.— General coloration light green. Face pale green, mandibles brightly emerald green, labrum dark brown. Tegmina green, with contrastingly yellow venation. Legs green; abdomen light green dorsally; purple ventrally; ovipositor light brown, with darker apex.

Measurements.— Table 15 .

Distribution.— This species seems to be distributed throughout Costa Rica ( Map 15 ), Panama, and Colombia.
