Kanakia gigas Boulard, 1988

( Figs. 2–3 )

Material examined. Holotype male and one paratype male, Nouvelle-Calédonie, Province Sud, Parc de la Rivière Bleue, 28/XII/1987, Boubinot & Legrand rec, à la lumière (MNHN). Allotype female and one paratype female, Province sud, Boulouparis, Mont Do, 03/XII/2013 Salesne rec, (MNHN). Other material: 7 males, Province Sud, Boulouparis, Mont Do, 15/XII/2009, Salesne rec, (Delorme personal collection); 1 male, same locality, 03/XII/ 2010, Salesne rec, (Delorme, personal collection); 3 males, same locality, 12/I/2013, Salesne rec (Delorme personal collection); 4 males same locality, 10/I/2015 Salesne rec à la lumière (Delorme personal collection); 1 male same locality, 23/XII/2013 Salesne rec à la lumière (Delorme personal collection); 1 male, Province sud, Dumbéa, Monts Koghi, 24/I/2013, Delorme rec (MNHN); 1 male, Nouvelle-Calédonie, Province Nord, Pouembout, Massif du Kopéto, (800 m), 21/I/2015, Quentin Delorme rec, caught by net, (Delorme personal collection).

Body measurements (in mm, 3 males from Province Sud, Boulouparis, Mont Do). FL: 63.5, 63.5, 64.8; FW: 22.5, 22.1, 22.8; HW: 11.6, 12.0, 12.0; HL: 3.8, 3.7, 3.7; BL: 55.0, 55.5, 55.5; PL: 7.0, 6.6, 6.9; PW: 12.8, 12.9, 13.1.

Male Diagnosis. Head green, about as wide as pronotum. Pronotum green, longer than head. Abdomen green. Legs green. Forelegs with femur bearing three developed brown spines. Forewings hyaline. On male genitalia, thecal pseudoparameres of aedeagus in dorsal position, originating closer to its apex than to its base, always much longer than theca. Claspers shorter than pseudoparameres, divergent, ending in a wide hooked spine in posterior part, and a smaller and shorter spine in anterior part (ice ax like).

Song patterns. Male calling song ( Fig. 2 ) formed only by long echemes, repeated at a low rate. Echemes duration varies between 0.8 s to 1.1 s. Each echeme are separated by intervals lasting around 15 s. Echeme amplitude range covers frequency from 1.3 kHz to 1.7 kHz. The maximum of energy is contended at 1.5 kHz.

Description of female ( Fig. 3 )

Head. Colouration similar to that of male (entirely green).

Thorax. Colouration of pronotum and mesonotum similar to that of male (entirely green).

Legs. Similar in colour to those of male (entirely green).

Abdomen. Conic, not as inflated as male abdomen. Tergites uniformly ocher to pale orange with black lateral spot on tergites 3 to 8; abdominal segment 9 ocher to pale orange with a pair of diffuse longitudinal near-dorsal black fasciae; dorsal beak terminally pointed; sternites colouration greenish to pale brownish.

Genitalia. Ovipositor sheath black with long golden hairs; reaching approximately the tip of dorsal beak of abdominal segment 9.

Body measurements (in mm, first value refer to allotype, second value refer to paratype female). FL: 64.5, 63.2; FW: 22.7, 21.5; HW: 12.2, 12.1; HL: 3.8, 3.7; BL: 45.5, 46.3; PL: 6.9, 6.7; PW: 13.1, 12.9.

Distribution. Rainforests of the Grande Terre of New Caledonia: Yaté (Parc de la Rivière Bleue), Dumbéa (Monts Koghi), Boulouparis (Mont Do), Pouembout, (Massif du Kopéto) ( Fig. 33 ).

Habitat and ecology. Kanakia gigas inhabits primary rainforests. The species was encountered from 500 m up to 900 m of altitude. We have no information on seasonality and peak period of emergence.
