Bioacoustics of Podacanthophorus maylinae

Diagnostic description.— The largest species of the genus; general characteristics as described above; wings in both sexes surpassing apices of hind femora by about fifth of their length. Fastigium of vertex twice as long as eye diameter, narrowly rounded apically, with distinct dorsal furrow dorsally; ventral keel of fastigium smooth ( Figs. 35 E, 35H). Male stridulatory file weakly curved, 1.4 mm long, 115 μm wide, with 310 closely spaced and relatively very wide teeth ( Fig. 51 B); stridulatory area on male without secondary venation; mirror square; secondary veinlet next to AA 1 present, divergent from AA 1. Ventral anterior spines of hind femora relatively short, as long as half of width of hind femur below knee ( Fig. 35 M). 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, distinctly constricted apically ( Fig. 34 F); female cercus simple, elongately conical, somewhat curved. Male titillators needle-like, straight but slightly bent outwards apically ( Fig. 34 G). Ovipositor short, sickle-shaped, slightly longer than half of hind femur (ratio ovipositor/hind femur 0.66-0.70). Coloration .— General coloration light green; face creamy white; fastigium reddish-brown; lower half of clypeus dark purple; metazona of pronotum in male with small, V-shaped, dark red spot, surrounded by thick, white margin; venation of tegmina and posterior edge of tegmina contrastingly yellow.
