Bioacoustics of Erioloides acutidentis

Diagnostic description.— Very similar to the previous species; fastigium of vertex more pointed than in other species of the genus ( Fig. 23 H). Male stridulatory file straight, 1.0 mm long, 103 μm wide, with 179 closely spaced and very wide, lamelliform teeth; teeth in proximal half of file thinner and more closely arranged than in distal part ( Fig. 50 C); mirror elongately rectangular, distinctly longer than wide; secondary veinlet next to AA 1 well developed, strongly divergent from AA 1; stridulatory area of left wing devoid of secondary venation. Male 10th tergite with small, narrow incision on posterior margin ( Fig. 22 F). Male cercus relatively slender, cylindrical, with small, spur-like dorsal spine; apex of cercus blunt ( Fig. 22 F-G). Female cercus simple, elongately conical, distinctly curved. Titillators not clearly differentiated from phallic membrane, squamose ( Fig. 23 C). Male subgenital plate with distinct ventral keel and deep triangular incision apically; female subgenital plate broadly triangular, with small, triangular incision at apex. Ovipositor relatively slender, with irregular lamella along midline of upper valvula; ratio ovipositor/hind femur 0.81. 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.
