Bioacoustics of Ischyra (Anapolisia) picta

Diagnosis. Vein MA with four main branches reaching wing margin ( Fig. 58 ). Tegmina slightly hyaline, with numerous small circular yellow and dark green spots ( Fig. 62 ). Thorax laterally with four dark green spots ( Fig. 57 ). Mesobasisternum lateral lobes anterolaterally and laterally convex, posteriorly concave, forming a posterolaterally blunt tip ( Fig. 57E ). Metabasisternum anteriorly straight with two small lateral convex projections; lateral lobes anterolaterally convex, laterally and posteriorly straight, posterolaterally forming an angle of 120° ( Fig. 57E ). Apex of cercus with rectangular projection and large lateral spine, with a dark brown color ( Fig. 57K ). Left stridulatory file slightly curved ( Fig. 59A ).

Description. Holotype Male. Thorax . Mesobasisternum triangular, anteriorly straight; lateral lobes anterolaterally and laterally convex, posteriorly concave, forming a posterolaterally blunt tip ( Fig. 57E ). Metabasisternum triangular, anteriorly straight with two small lateral convex projections; lateral lobes anterolaterally convex, laterally and posteriorly straight, posterolaterally forming an angle of 120° ( Fig. 57E ). Wings. Vein MA with four main branches reaching wing margin ( Fig. 58 ). Left stridulatory file slightly curved; apical and basal teeth smaller ( Fig. 59A ). Total file length of 2.1 mm, greater vein width of 0.4 mm and total of 62 teeth. Right stridulatory slightly curved; basal teeth more spaced apart ( Fig. 59B ). Total length file of 1.9 mm, widest vein of 0.2 mm and total of 59 teeth. Legs . Hind femur with expanded region equivalent to 2/3 of the total femur length ( Fig. 57H ). Abdomen . Cercus slightly curved inwards, with the apex not expanded ( Figs. 57I–K ). Apex of cercus with rectangular projection and large lateral spine, with a dark brown color ( Fig. 57K ). Stylus small and triangular ( Fig. 57I ). Internal male genitalia. Ejaculatory vesicles reniform ( Figs. 60A–D ). Upper folds of ventral lobe elongated, narrow and connected ( Figs. 60A–B ). Titillator process elliptical ( Figs. 60A–D ). Lower folds of ventral lobe large, triangular and exceeding the dorsal lobe ( Figs. 60A–B ). Dorsal lobes anteriorly, laterally and posteriorly convex ( Figs. 60A–D ). Dorsal folds elongated and asymmetrical ( Figs. 60C–D ). Coloration . Described based on photos of live specimens ( Fig. 62 ). General color of the body light green. Eyes purple. Thorax laterally with four dark green spots. Abdomen whitewish-green. Tegmina slightly hyaline, with light green coloring; radial branches with numerous small circular yellow spots; cubital and median branches with small dark green spots; margins of tegmina and apex of the membranous wing with narrow yellow band Female: Morphologically similar to the male, except by the following characteristics ( Figs. 61A–K ): Thorax . Mesobasisternum triangular, anteriorly convex; lateral lobes anterolaterally, laterally and posteriorly convex, forming a posterolateral acuminate tip ( Fig. 61E ). Metabasisternum triangular, anteriorly straight; lateral lobes anterolaterally convex, laterally and posteriorly straight, posterolaterally forming an angle of 100° ( Fig. 61E ). Wings . Unaltered anal veins for sound production ( Fig. 61A ). Abdomen . Cercus slightly curved inwards, apex acuminate ( Figs. 61H–J ). Subgenital plate triangular, apex rounded and stylus absent ( Fig. 61H ). Ovipositor curved; apical region of dorsal and ventral valve with small rectangular teeth ( Fig. 61J ). Coloration . Based on photos of preserved specimen ( Fig. 61 ). Body yellowish-brown. Eyes dark brown.
