Bioacoustics of Larnaca (Larnaca) infolda

Figure 2 , Map 1 Description. Male. Body medium. Frons smooth, fastigium verticis about 1.7 times as broad as scape, apex truncate ( Fig. 2 A). Eye ovoid, ocelli inconspicuous, lateral margin flat. Apical segment of maxillary palpus longer than previous segment, apex inflated, truncate. Anterior margin of pronotum slightly projecting, posterior margin almost straight; lateral lobes longer than high, posterior margin slightly extended downward ( Fig. 2 B, D). Tegmina slightly shorter than the length of pronotum but longer than 2 mm , left and right ones not overlapping, apices reaching the middle of first abdominal tergite; hind wings transparent shorter than tegmina ( Fig. 2 B, C). External margin of fore coxae with 1 small spine; fore femora unarmed on ventral surface; fore tibiae with 4 pairs of spines and 1 pair of apical spines on ventral surface. Middle femora unarmed on ventral surface; middle tibiae with 4 pairs of spines and 1 pair of apical spines on ventral surface; dorsal surface of middle tibiae without internal apical spine. Hind femora with 9–10 external spines on ventral surface, internal spines inconspicuous; hind tibiae with 6 pairs of spines on dorsal surface, 1 pair of dorsal apical spines, 2 pairs of ventral apical spines, and 1 pair of ventral subapical spines. Lateral margins of second and third abdominal tergites without stridulatory teeth. Eighth abdominal tergite significantly prolonged backward, about 2 times as long as seventh abdominal tergite, nearly rectangular in dorsal view. Ninth abdominal tergite prolonged, curved ventrad, nearly trapezoidal in dorsal view, centre of posterior margin divided into two crossed and spine-shaped lateral lobes which directing outward and strongly folded inward; basal area of lateral lobes with rounded convexities, apices acute ( Fig. 2 E–G). Lateral margins of basal half of subgenital plate arc-shaped expanding, apical half nearly trapezoid, narrowing from middle area to apex, posterior margin almost straight, centre slightly concave ( Fig. 2 L). Styli conical located on both sides of near centre of subgenital plate. Female. Appearance is similar to male. Copulatory depressions of seventh abdominal sternum significantly prolonged backward, forming 1 pair of small lateral lobes, the area between them concave upward. Subgenital plate broad basally, apex obtusely rounded, posterior margin with a shallow notch in the middle ( Fig. 2 M). Ovipositor curved upward strongly, dorsal margin and ventral margin smooth, apex acute ( Fig. 2 N). Coloration. Body yellowish brown. Frons black, between antennal sockets with 1 black spot, fastigium verticis and occiput with some black spots ( Fig. 2 B, I). Ventral edges of antennal sockets black. Eyes blackish brown ( Fig. 2 A). Pronotum with black spots ( Fig. 2 B, D). Both sides of posterior margins of mesonotum, metanotum and first abdominal tergite black ( Fig. 2 B, C). Fore and middle tibiae with spines blackish brown. Apical areas of hind femora, apical and basal areas of hind tibiae black. Hind femora with blackish brown ventral spines, hind tibiae with black dorsal spines. Measurements (mm).
