Bioacoustics of Habetia imitatrix

Description. General habitus of the genus. Coloration of face of general color; mandibles fully black; antennal scrobae with indistinctly darkened spot at ventro-internal angle. Femora with the following number of spines on ventral margins: (1) a 6 p 6; (2) a 7 p 3; (3) a 9–12 p ca 11 (n = 1). Male. Stridulatory file on underside of left tegmen with a distinct step in distal area; file length 2.50 mm with 78 teeth, of which narrow curved basal area 0.25 mm with 8 teeth, central area 1.58 mm with 37 teeth, step 0.15 mm with 5 teeth, narrow apical area 0.54 mm with 28 teeth ( Fig. 18D ). Tenth abdominal tergite with convex surface; from hind margin with a long and narrow oval incision closed from behind by projecting acute angles from tip of resulting gap. Cerci moderately curved and little narrowing towards end; from little before mid-length with a dorso-ventrally compressed inner ridge that widens to a wide and compressed internal process, which divides towards end into two compressed, wide, and little curved lobes, the proximal branch little larger than the distal branch, both with a minute denticle at tip, the proximal branch also with a dorsal carina from base of process; inner surface of cercus between these projections and upper margin little concave and terminated dorsally by a narrow rim ( Fig. 8A ). Subgenital plate roughly semi-circular with a long and narrow medial projection; in ventral view deeply incised from base and membranous between resulting oblique anterior margins; sclerotized area with convex and later concave lateral margins forming a long and narrow apical projection with a fine medial carina and acute and laterally compressed tip; this rather high and towards ventral margin laterally compressed projection obviously results from a widened fusion of the dorsal lateral margins with the ventral, medial carina, it is in lateral view obliquely truncate at end and carries 3 larger transverse teeth in upper and a few minute denticles in lower area ( Figs 11E , 12F , 14F ). Titillators mostly black; at base little recurved and with narrowing margins, then straight and approaching each other; before performing a curvature slightly widened and diverging, then performing a more than 180° curve, in apical area straight with parallel margins and truncate but with shortly recurved tip ( Figs 12G–I ); lateral sclerites elongate, of same color as titillators, with rounded ends and a small notch in about mid-length. Female unknown. Measurements ( 1 male ).—Body w/o wings: 35; pronotum: 9.3; tegmen: 33.5; hind femur: 24.5 mm .
