Bioacoustics of Podacanthophorus vargasi

Diagnostic description.— 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 AA 1 present, thick, divergent from AA 1. 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). Coloration .— 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.
