Gena yellowish and lorum with inferior part blackish, lateral margin and superior part yellowish covered by dense and long silvered hairs.

Thorax. Pronotum green, with black median posterior fasciae showing a pentagonal shape ( Fig. 10 ); paramedian fissure greenish; lateral fissure with brown ornamentations. Pronotal collar green. Lateral parts of pronotal collar with two prominent green lobes; posterior lobe semi-circular with brown anterior spot coming from ambient fissure. Ambient fissure of pronotum black. Mesonotum mostly brown with green longitudinal ornamentations along parapsidal suture and median part. Scutal depression marked by circular black patch. Metanotum and cruciform elevation entirely brown. Opercula yellow, domed with sparse long hairs on margin.

Wings. On forewings, radial and radiomedial crossveins with brown infuscation. Hindwing hyaline; ambient vein brownish, vannus and jugum hyaline with brown infuscation at margin.

Legs. Fore legs with coxa brownish with edges of lateral sides green; trochanter greenish with wide brownish patch in inner side. Femur greenish with wide brown longitudinal lines. Tibia brownish with short golden hairs. Mid legs with coxa greenish to yellowish with wide linear brown spot on medio anterior side; trochanter greenish with wide brownish patch in inner and lateral side; femur greenish with three longitudinal brown lines on interior side; tibia and tarsus entirely green/brownish covered by short golden hairs.

Abdomen. Tergite 2 entirely yellow. Tergites 4 to 7 with discontinuous dorsal black median line. Tergites 3 to 7 yellow with black lateral spot wide at base and getting thinner upwards, occupying a third of tergite width on tergites 3 to 5 and fading on tergites 6 and 7. Tergite 8 yellow with wide black spot occupying two third of anterior part. Sternites 1 to 8 entirely yellow. Timbals bear series of three short ribs and four long ribs connected by dorsal bar and running dorsoventrally to the timbal plate; long ribs 1 and 2 fused ventrally.

Genitalia. Pygofer yellow with a pair of lateral small black patches at base. Median lobe of uncus curved downwards and obtuse with wide shallow median furrow. Thecal pseudoparameres of aedeagus slender, curved downwards and undulated.

Body measurements (in mm, first value refer to holotype, second and third value refer to paratypes males). FL: 49.1, 51.8, 49.4; FW: 17.0, 17.8, 16.4; HW: 10.2, 10.8, 10.5; HL: 4.1, 4.3, 4.1; BL: 39.3, 41.7, 40.8; PL: 4.9, 5.4, 5.0; PW: 10.1, 11.0, 10.4.

Song patterns. Male calling song ( Fig. 15 ) formed only by short echemes repeated at very low rate. Echemes duration vary between 61 to 81 ms. Each echemes composed by 3 or 4 groups of pulse and separated by intervals lasting between 5.9 s to 11.7 s. Echeme amplitude range covers frequency from 1.4 kHz to 4.1 kHz. The main energy is contended between 1.7 kHz to 2.6 kHz and a maximum of energy at 2.2 kHz.

Female ( Fig. 14 ). Head. Colouration similar to that of male.

Thorax. Colouration and black ornamentation of pronotum similar to that of male. Mesonotum colouration similar to that of male.

Legs. Similar in colour to those of male.

Abdomen. Tergites darker in colouration to those of male with similar lateral black ornamentations; abdominal segment 9 yellowish with a pair of longitudinal near-dorsal black fasciae that extend to the anterior edge and ventrolaterally to some extent, dorsal beak terminally pointed; sternites colouration similar to that of male. 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 and third value refer to paratypes females). FL: 47.5, 51.0, 53.3; FW: 14.5, 16.8, 18.7; HW: 10.4, 10.8, 11.7; HL: 3.8, 3.8, 4.5; BL: 32.4, 36.0, 40.5; PL: 5.5, 5.8, 6.5; PW: 10.6, 11.0, 12.3.

Distribution. North-east coast of New Caledonia (Mont Panié, Forêt de Toveine and Roches de la Ouaième) ( Fig. 33 ).

Habitat and ecology. Kanakia paniensis Delorme sp. nov., inhabits primary rainforests and old mining forest formation where niaouli trees ( Melaleuca quinquenervia ) are dominant. Males generally call set on the trunk of Niaouli trees or trunk of big trees, from 2 m high to base of tree crown. It appears not gregarious, but two or three males can call on the same trunk. Call activities occur as well on daylight as 1 to 2 hours after sun set. In the Mont Panié area, reproduction stations are localized in deep soils where old niaouli trees are growing. In this station many exuviae where collected and many larva found in the ground. On both stations, the species was encountered from 500 m up to 600 m. We have no information on seasonality and peak period of emergence.
