Bioacoustics of Habetia curvata

Description. Coloration of face uniformly pale, of general color; mandibles black, only a small area at base light ( Fig. 3D–E ). Femora with the following number of spines on ventral margins: (1) a 6–7, p 6–8; (2) a 7, p 3; (3) a>10, p>14 (n=1). Male. Stridulatory file on underside of left tegmen with a distinct step in distal area; with 79 teeth, of which 7 narrow teeth at base, 41 in main part of file, 5 at a step, 15 clearly separated at end, and 11 of decreasing size at end ( Fig. 17F ). Tenth abdominal tergite transverse, nearly parallel-sided; at base wide roundly incised in middle; surface with a medial furrow and with a long narrow apical incision from hind margin through which the epiproct is visible; at both sides of apical incision hind margin faintly slanting mediad. Cerci narrow elongate, faintly curved, behind basal area with an internal carina that forms a small projecting lobe before mid-length of cercus; internal surface, especially behind mid-length excavated with the ventral margin prolonged into a curved-triangular internal process that terminates into one acute spine, the hind margin of that process carries a minute tubercle at about end of basal third; the cercus stem ends into a short cone behind the internal process ( Figs 11D , 17D ). Subgenital plate strongly incised from base to almost mid-length; lateral margin convex in basal, straight in apical area, dorsal-lateral margin partly with laterally expanded rim; apical margin in middle roundly incised; with a pair of rather long styli ( Fig. 11D ). Titillators moderately widened at base that is curved ventro-apicad, then simply band-shaped, from around mid-length apical area curved ventro-apicad and widened to an oval extension that has the proximal margin markedly widened in middle; apical area narrowed and recurved, with obtuse tip. Phallus also provided with a pair of small circular sclerites at top of titillators and with a pair of elongate lateral sclerites ( Fig. 17E ). Female. Subgenital plate with lateral margins upcurved and approaching each other posteriorly and with a shallow furrow along midline, at end terminating into a pair of narrow spine-like projections, apical margin between bases of projections subtruncate, very faintly projecting in middle; above apical margin and between bases of apical projections with a compressed, upright lamella with faintly bilobate margin ( Fig. 5G ). Measurements ( 1 male , 1 female ).—Body w/o wings: male 30, female 35; pronotum: male 8.7, female 9.5; tegmen: male 30, female 36; hind femur: male 27, female 27; ovipositor length: female 62 mm .
