Bioacoustics of Holochlora falcata

Description. Habitus typical for genus; medium in size compared to congeners; head, pronotum, tegmina and legs when alive generally green, yellow when preserved ( Figs 9G, 9H , 13B ). Eyes in dorsal view globular and slightly protruding anteriorly; in frontal view slightly longer ( Figs 9H, 9I ). Frontal rostrum somewhat flattened, triangular, stout, with rounded apex and median sulcus indistinct ( Fig. 9H ). Antennal scapus with a tint of pinkish red; pedicles mainly pinkish red; and segments pinkish red ( Figs 9H, 9I ). Face and mouthparts generally light coloured, median ocellus large and pyriform ( Fig. 9I ). Pronotal disc with anterior margin straight in middle, posterior margin rounded ( Fig. 9H ); pronzona 1.4 times longer than metazona. Pronotal lobe 1.2 times taller than long; ventral margin short and rounded ( Fig. 9G ). Tegmen relatively narrow and unicolourous green ( Fig. 13B ). Legs generally green. Fore tibia with inner tympanum conchate, slightly swollen, with broad slit opening, around tympanum and knee black ( Fig. 10G ); with outer tympanum pyriform ( Fig. 10H ). Hind femur with genicular area green, external lobes bispinose, dorsal spine subacute, ventral spine acute ( Fig. 10I ). Male. Left tegmen with vein 1A swollen, typical for genus, somewhat transversely oblong but at anal end slightly narrower ( Fig. 11E ); right tegmen with vein 1A mostly substraight with basal end faintly curved and mirror bowl-shaped with distal end distinctly shorter than basal end ( Fig. 11F ). Stridulatory file on left tegmen stout, typical for genus; straight with ca. 30 fairly widely-spaced, equally-spaced and equally-sized teeth and 7 additional smaller stout teeth at basal end ( Fig. 12C ). Abdominal apex as shown in Fig. 16 : tenth abdominal tergite in middle with raised triangle; its posterior margin broadly rounded, in middle with two bulbous lobes; lobes obtusely rounded; between lobes narrowly emarginated. Cercus large, flattened and strongly curved, with apex flattened tooth-like, truncated. Subgenital plate broad basally, narrowing in basal third into narrow shaft with lateral margins parallel. At apical end with two lateral lobes; apical lobes slightly longer than half the length of the subgenital plate; between lobes broadly and angularly emarginated. Styli flattened, elongated, with apices rounded. Female. Unknown. Measurements ( ♂ holotype , in mm). BL = 18.9; BWL = 44.9; PL = 5.4; PW = 3.5; TL = 36.9; TW = 6.3; HWT = 3.4; HFL = 20.2; HFW = 2.4; HTL = 23.4.
