FIG. 1 in Panoploscelis scudderi Beier, 1950 and Gnathoclita vorax (Stoll, 1813): two katydids with unusual acoustic, reproductive and defense behaviors (Orthoptera, Pseudophyllinae)
FIG. 1. — Variations in characters used to distinguish Panoploscelis scudderi Beier, 1950 and Panoploscelis angusticauda Beier 1950 n. syn. females. The speci- mens pictured are breed from samples collected in Mitaraka (F1 and F2 generations). The frequent-most condition is represented in the left panels (A, E, J). Specimens from Mitaraka display variations in: A-D, the number of tubercle-bearing veins; E-I, the shape of ovipositor in side view (holotype of P. angusticauda display the same shape of ovipositor as illustrated in F); J-N, the shape of epiproct hind margin (male juvenile holotype of P. scudderi display the same shape of epiproct hind margin as illustrated in N; in P. angusticauda, the hind margin is somehow as in K). Scale bars: 10 mm.
