Figs. 22 J-K, 23E, 49E, Map 15

Type locality: Costa Rica, Alajuela Prov., Sector Colonia Palmareña; type depository: Academy of Natural Sciences, Philadelphia – holotype male

Diagnostic description.— Very similar to previous species. Male stridulatory file straight, 1.1 mm long, 145 μm wide, with 220 closely spaced and extremely wide, lamelliform teeth; teeth in proximal half of file thinner and more closely arranged than in distal part ( Fig. 49 E); mirror approximately rectangular, distinctly longer than wide; secondary veinlet next to AA 1 well developed, slightly 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 small, triangular apical incision ( Fig. 22 J). Male cercus relatively slender, cylindrical, with thin, finger-like dorsal spine; apex of cercus somewhat constricted ( Fig. 22 K). Female cercus simple, elongately conical, distinctly curved. Titillators flattened, squamose, apices multidentate, strongly divergent. 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; ratio ovipositor/hind femur 0.74-0.78.

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 new species seems to be widely distributed in Costa Rica, with most records from low or mid elevation forest habitats ( Map 15 ).
