Diagnostic description.— General characteristics as described above. Fastigium of vertex strongly developed, about 4 times as long as diameter of eye and, at its base, about twice as wide as eye diameter, slightly bent apically; ventral basal tooth of fastigium prominent; gap between fastigia of vertex and frons deep, about as wide as scapus ( Figs. 15 A-C).

Stridulatory file of male 2.87 mm long, with 70 lamelliform teeth (n=1), maximum width of file 0.23 mm ( Figs. 46 E-F). Male cercus as in Figs. 14 D-E. Ovipositor distinctly bent upwards, shorter than hind femur (ratio ovipositor/hind femur 0.77), not reaching apex of tegmina ( Fig. 15 A).

Coloration.— Body coloration of most specimens from Costa Rica tan to sienna brown, dorsum of head and pronotum with dark brown (raw sepia), wide stripe; less frequently entire body pale green, with no dark stripe on dorsum.

Measurements.— Table 11.
