Bioacoustics of Habetia tuta

Description. Coloration of face uniformly pale, of general color; lateral areas of face and genae little darker than central area of face, which might be due to conservation; antennal scrobae faintly darkened; mandibles black with few small yellow and dark red spots. Femora with the following number of spines on ventral margins of legs: (1) a 5–8, p 4–8; (2) a 7, p 2–4; (3) a 11–15, p 14–16 (n=3). Male. Stridulatory file on underside of left tegmen with a distinct step in distal area, in holotype with 66 teeth, of which 7 narrow teeth at base, 36 in main part of file, 5 at a step, 13 clearly separated at end, and 6 of decreasing size at end ( Fig. 18A ), in paratype with 69 teeth, of which 8 narrow teeth at base, 35 in main part of file, 5 at a step, 13 clearly separated at end, and 6 of decreasing size at end. Mirror behind stridulatory file with straight anterior and posterior margins and convex lateral margins; slightly longer than wide, greatest width anteriorly. Tenth abdominal tergite transverse, in midline furrowed and at fore margin with an obtuse-angular incision filled by membrane, from hind margin with a narrow elongate triangular sub-membranous area; fully sclerotized areas with apical margin obtuse-angular but with rounded angle above bases of cerci ( Fig. 8B ). Cerci in about basal half roughly cylindrical, in apical half with an obtuse dorsal carina and strongly concave internal surface; at end of cercus, at dorsal margin from nearly tip, at ventral margin from beginning of apical third with a large internal projection with concave proximal surface that is before end divided into a short rounded dorsal process with narrowing margins that ends into an acute black spine, and into a small compressed ventral flap that is curved posteriorly, surpasses the dorsal spine, and carries a minute black spinule at tip ( Fig. 12A ). Subgenital plate with convex lateral margins that form in basal two thirds a wide, dorso-ventrally compressed rim that frame the strongly convex central area that is dived from base to nearly apical third into a pair of ovoid hemispheres; apical area short and narrow, flattened and with a faint median carina, with two short styli ( Fig. 11A ); above the subgenital plate there is a semi-tube-shaped sclerotized phallus sheath that holds the phallus when at rest, it has the dorsal margins faintly granular and terminates into a pair of separate rounded lobes ( Fig. 8B ). Its function is unknown. Titillators simple, laterally compressed, dark or red brown, forming a pair of simple, curved sclerites; at base faintly curved, then straight, followed by an about 150–160° curve, in apical area faintly narrowed, tip rounded ( Figs 12B–C ). With a pair of spindle-shaped narrow elongate lateral sclerites. Female. Subgenital plate rhombic with up curved lateral margins that are in basal area strongly prolonged dorsad; at apico-lateral angles with up-bent acute cones ( Figs 5E–F ). Ovipositor almost twice as long as body; behind basal constriction straight with dorsal valves in basal half faintly higher than in apical half; dorsal margin faintly convex but not raised ( Fig. 1B ). Measurements ( 2 males , 1 female ).—Body w wings: male 44–45, female 53; w/o wings: male 33–37, female 39; pronotum: male 9.2–9.5, female 10; tegmen: male 33–34, female 40; hind femur: male 23–24, female 29; ovipositor length: female 69; ovipositor height: female 2.7 mm .
