Anterior margin of pronotum in form of spine. Pronotum strongly bulging. Legs moderately tuberculated. DISTRIBUTION. — Known only from New Caledonia. DESCRIPTION Frontal costa bifurcation in upper third of eye height. Scutellum narrow, slightly widening ventrad. Paired ocelli at middle of eye height. Midline of antennal grooves at level of ventral margin of eyes. Antennae filiform, long, composed of 14 visible segments. Vertex nearly twice as wide as eye in frontal view. In anterior view, vertex above level of upper margin of eyes; rounded, bulging. In dorsal view, vertex covered by pronotum. Anterior margin of pronotum in form of spine. Prozonal carinae barely distinct, parallel. Median carina distinct and elevated throughout its length. Lateral lobes projecting outwards, rectangular, pointed backward. Ventral sinus blunt but narrow. Tegminal sinus absent. Infrascapular area very wide above middle femur, narrowing slightly towards pronotal apex. Humeral angles blunt. Posthumeral spots absent. Pronotal apex wide. Tegmina and wings absent. Anterior femur smooth; dorsal margin a little wavy; ventral margin with small tubercle in distal third. Anterior tibia straight and smooth. First segment of anterior tarsus a little shorter than second segment (minus claws), pulvilli indistinct. Dorsal margin of middle femur smooth; ventral margin with three wide protrusions. Middle tibia straight and smooth. Hind femur robust, mostly smooth; small antegenicular and genicular tooth. Hind tibia straight and smooth with small teeth in distal two thirds. First tarsal segment a little longer than third. Distal pulvillus longer than middle one, third pulvillus shortest, all blunt. REMARK The specimens listed above are exclusively nymphs. Since nymphs have raised carinae, it is often difficult to confidently assign them to a certain species, especially if no adults were collected from the same locality. The new species described here can be easily separated from each other in adult stages, but more research is necessary to determine the phylogeny of this genus and to make sense of its distribution.
