Each ocellus set on yellowish part of vertex. Eyes greenish, prominent, wider than long. Epicranial suture deep yellowish to greenish. Dorsal postclypeal uniformly greenish. Scape yellowish and supra-antennal plate entirely blackish. Antennal flagella and pedicel black. Posclypeus slightly domed yellowish with wide median blackish spot notched in its superior part; the notch reaching half of the spot or reaching the sixth transversal groove. Anteclypeus bicolor; lateral parts blackish covered by long silvered hairs and median part yellowish to greenish and hairless. Rostrum with labrum and mentum greenish.

Pronotal collar greenish to yellowish; lateral parts with two prominent green lobes; posterior lobe with brown anterior spot coming from ambient fissure. Mesonotum mostly brown with wide green ornamentations along parapsidal suture and median part. Scutal depression with circular black patch. Metanotum and cruciform elevation entirely brown. Opercula brownish, domed with sparse long hairs on the 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.

Femur greenish with wide brown longitudinal lines, bearing three spines. Tibia brownish with short golden hairs. Mid legs with coxa greenish to yellowish with 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; tibiae and tarsi entirely brownish covered by short golden hairs.

Abdomen. Tergites much darker than in K. paniensis Delorme n. sp. and K. typica in overall; tergite 2 entirely yellowish. Tergites 3 to 7 with dorsal discontinuous black median line. Tergites 3 to 7 greenish with black lateral spot wider at base and getting thinner upwards, occupying at least half of tergite width on tergites 3 to 5 and fading on tergites 6 and 7. Tergite 8 mostly black with posterior third greenish. Sternites 4 to 8 yellowish with wide black lateral margin. Timbal with four longs ribs fused dorsally; ribs 1 and 2 fused ventrally; three intercalary short ribs.

Body measurements (in mm, first value refer to holotype, second and third value refer to paratypes males). FL: 62.3, 51.0, 51.7; FW: 19.5, 17.1, 18.2; HW: 12.7, 10.5, 10.8; HL: 4.4, 4.1, 4.2; BL: 47.5, 40.5, 42.0; PL: 5.4, 6.0, 5.5; PW: 13.1, 10.2, 10.7.

Song patterns. Male calling song (Fig. 21) formed by short echemes repeated at constant rate of one echeme every 10 to 11 seconds in normal condition. Echemes duration varies between 45 to 62 ms. Each echemes composed by 3 or 4 groups of pulse. Echeme amplitude range covers frequency from 1.2 kHz to 4 kHz. The main energy is contended between 1.5 kHz to 2.9 kHz and a maximum of energy at 2.4 kHz.

Female (Fig.20). 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 of allotype (in mm). FL: 51.0; FW: 18.3; HW: 11.2; HL: 4.1; BL: 35.9; PL: 5.8; PW: 11.0.

Distribution. North-west coast of New Caledonia (Koumac, Tiébaghi montain) (Fig. 33).

Habitat and ecology. Kanakia salesnii Delorme sp. nov. inhabits old mining forest formation where Niaouli trees (Melaleuca quinquenervia) are dominant and deep humid soils formation where Mango tree (Mangifera indica L.) and Banyan tree (Ficus spp.) are growing. The station discovered at Tiébaghi is localized on ultramafic soils. Reproduction station localized in abandoned garden of the old village. In this station many exuviae where collected. No information is available on seasonality and peak period of emergence.
