Bioacoustics of Erioloides macrocephalus

1 . Male 10th tergite with two short, rounded lobes ( Fig. 20 E); female 10th tergite with deep, narrowly triangular incision. Male cercus relatively robust, distinctly incurved; its apex constricted; subapical inner spine small, blunt ( Figs. 20 D-E). Female cercus simple, elongately conical, distinctly curved. Titillators flattened, squamose, distinctly dilated apically, apices multidentate ( Fig. 20 F). Male subgenital plate with distinct ventral keel and deep triangular incision apically; female subgenital plate widely triangular, with wide, semicircular incision at apex. Ovipositor robust, with distinct file of pegs along midline of upper valvula ( Fig. 20 G); ratio ovipositor/hind femur 1.04-1.07. Coloration .— General coloration light green. Upper portion of face green, lower portion of face, upper half of clypeus, and mandibles black; lower half of clypeus and labrum yellow ( Fig. 20 B). Tegmina green, with contrastingly yellow venation. Legs green; abdomen light green; ovipositor brown, with dark, nearly black apex. Measurements .— Table 15 . Bioacoustics.— Call unknown.

Diagnostic description.— General characteristics as described above. The largest species of the genus, body robust; wings in both sexes surpassing apices of hind femora by about half their length ( Fig. 20 A). Fastigium of vertex blunt, about as long as eye diameter and twice as wide as scapus ( Fig. 20 B). Face convex, distinctly punctate; genal carinae of head poorly developed but usually discernible. Dorsal surface of pronotum relatively rugose; flat; anterior margin of pronotum straight, posterior one convex ( Fig. 20 C); lateral lobes of pronotum about 1.7 times longer than high. Male stridulatory file straight, 1.8 mm long, 229 μm wide, with 187 closely spaced and relatively very wide, lamelliform teeth; teeth in proximal half of file much thinner and more closely arranged than in distal part; teeth on proximal end of file peg-like, irregularly clustered ( Fig. 49 C); mirror approximately rectangular, slightly longer than wide; secondary veinlet next to AA 1 present, well developed; stridulatory area of left wing devoid of secondary venation, secondary veinlet next to AA 1 present, somewhat divergent from AA
