Delorme, Quentin, Mille, Christian & Jourdan, Hervé, 2016, A review of the genus Kanakia Distant, 1892 (Insecta: Hemiptera, Cicadoidea, Cicadidae) from New Caledonia, Zootaxa 4092 (3), pp. 301-338 : 335-336

PANIALNA Delorme gen. nov.

( Fig. 35 )

Type species. Panialna parva (Boulard, 1991) comb. nov.

Included species. Only one species coming from New Caledonia: Panialna parva (Boulard, 1991) .

Derivation of name. Comes from “Mont Panié”. The genus is feminine.

Diagnosis. Medium sized cicada (male body length 26.5 mm), more or less close to the genus Kanakia Distant, 1892 with which it shares a similar opercula shape and wing venation. Differs mainly in clasper morphology (conic, slightly curved and smooth ( Fig. 35 c), aedeagus shape (thecal pseudoparameres originating near thecal base, apically curved inwards ( Fig. 35 a & b)) and head shapes (narrower than width of mesonotum between wings).

Material examined. Holotype male and 1 paratype male, P rovince Nord, Hienghène, Mont Panié (1,300 m), Chazeau, Dugdale & Baylac rec at light, 11–15/XII/1990 MNHN).

Head. Clearly narrower than width of mesonotum between wings; length inferior to pronotum. Dorsal postclypeal area about as wide as long; its anterior border slightly prominent from the curve of the supra-antennal plate. Postclypeus anterior profile in dorsal view well rounded giving the head an angular appearance. Big sized ocelli; distance between lateral ocelli longer than distance between lateral ocellus and median ocellus. Distance between lateral ocelli about equal to one ocelli size and about equal to distance between lateral ocellus and eye. Epicranial suture very deep. Postclypeus bears at least six transversal grooves and a not well marked longitudinal furrow.

Thorax. Paranotum (lateral margin of pronotal collar) when viewed dorsally, smooth with only a rounded lateral lobe and completely lacking anterior lateral tooth or angular projection. Male operculum, covering rim of distal margin of tympanal cavity, overlapping, not meeting; directed towards distomedial margin of tympanal cavity, apically broadly rounded.

Wings. Forewings with eight apical cells; radial and radiomedial crossveins vertical. Forewing veins M and CuA meeting basal cell clearly separated, immediately diverging; distance between r and r-m much less than distance between r-m and m; forewing infuscation present on crossvein r and r-m. First apical cell’s base located close after half of pterostigma length; slender, briefly reduced at tip and terminally sharpen; its length superior to half of costal vein length. Hind wings with six apical cells; anal cell 3 short, reaching middle of anal cell 2.

Legs. Forelegs with femur bearing three developed black spines. Primary spine strong and oblique, isolated, much shorter than distance separating primary and secondary spines. Second spine sharp, perpendicular, shorter than primary spine; apical spine oblique, triangular, distinctly shorter than second spine. Hind legs similar to mid legs, with three tibial latero-internal spurs and two latero-external spurs.

Abdomen. Ogival shaped, sharply reduced posteriorly, not much wider than mesonotum. Timbals broad, bearing four long ribs not fused ventrally; ribs 1 to 3 fused dorsally; three intercalary ribs. Male sternites domed; sternite 1 with a large rounded bulge; sternite 7 shape about as long as wide or longer, apex rounded.

Genitalia. Upper lobes of pygofer flat, well developed, longer than wide dominating pygofer between basal lobes and dorsal beak; basal lobes undivided, moderately developed, rounded in lateral view, abutted against or partly tucked behind pygofer margin; dorsal beak present as a developed apical spine or pointed apex and a part of chitinized pygofer. Median lobe of uncus flat, shorter than wide. Thecal pseudoparameres slender, lateral of theca, originating near thecal base ( Fig. 35 a & b). Claspers conic, smooth and slightly curved inwards. Pseudoparameres apically curved and sharp, apically strongly convergent. Aedeageal basal plate in lateral view angled at about 45°.
