Germalna, Delorme, 2018

Delorme, Quentin, 2018, Germalna, a new genus for the New Caledonian cicada previously assigned to the genus Melampsalta Kolenati, plus a complement to the description of the genus Rouxalna Boulard, with the description of two new species (Insecta: Hemiptera, Cicadoidea, Cicadidae), Zootaxa 4377 (1) : -

Genus Germalna gen. nov.

( Fig. 1 )

Germalna germaini nom. nud. BOULARD (2006), P. 131, 132,181; SANBORN (2013), P. 528, 789.

Type species. Melampsalta germaini Distant, 1906 , 387. [Type locality: New Caledonia], mono-specific genus coming from New Caledonia.

Included species. Only one species , Germalna germaini comb. nov.

Etymology. Genus name derived from the species name “ germaini ”. Gender feminine.

Diagnosis. Among the New Caledonian genera, Kanakia Distant, 1892 , Ueana Distant, 1905, Panialna Delorme, 2016a , Pseudokanakia Delorme, 2016a , Vastarena Delorme, 2016 , Bispinalta Delorme, 2017a , and Melanesiana Delorme, 2017a , can be distinguished from Germalna gen. nov., by the medial veins and cubitus anterior vein meeting the basal cell clearly separated or affiXed but distinct while Germalna gen. nov. has the medial vein and cubitus anterior vein meeting the basal cell with their stems confluent. Mouia Distant, 1920, differs by the larger size, the pedunculate eyes, the postclypeus anterior profile in dorsal view nearly straight giving the head a very blunt appearance; Paulaudalna Delorme 2017a , is much larger, has opercula covering the rim of the distal margin of the tympanal cavity; Myersalna Boulard, 1988b , has pedunculate eyes and the postclypeus anterior profile in dorsal view nearly straight giving the head a very blunt appearance; Murmurillana Delorme, 2016b , has pseudoparameres lateral of the theca originating near the thecal base and apically curved at right-angles, the postclypeus anterior profile in dorsal view is nearly straight giving the head a very blunt appearance; Rouxalna Boulard 1999, have an inflated pterostigma on the fore wings and the postclypeus anterior profile in dorsal view is nearly straight giving the head a very blunt appearance; Strepuntalna Delorme, 2017a has stringy pseudoparameres, dorsal of and much longer than the theca (> 3 time longer), originating near the thecal base; Poviliana Boulard, 1997 and Caledopsalta Delorme 2017b , also have narrow pseudoparameres, much longer than the theca (> 3 time longer) and apically straight. According to Marshall et al. (2016) Tettigetta Kolenati, 1857 and Mezammira Fieber, 1876 (European genera) seem to show some relationship with Germalna gen. nov according to the molecular data. However these two genera differ by the presence of a well developed upper lobe on pygofer, a shorter median lobe of the uncus and sternite VIII is as long as sternite VII. In addition, species of Mezammira have an inner tooth on the basal lobe of the pygofer and the pseudoparameres are flat.

Description. Head. As wide as mesonotum. Dorsal postclypeal area wider than long; anterior border prominent from the curve of supra-antennal plate. Postclypeus anterior profile in dorsal view well rounded giving the head an angular appearance. Epicranial suture deep. Postclypeus bearing at least siX transverse grooves and a longitudinal suture.

Thorax. Lateral margin of pronotal collar smooth with only a rounded lateral lobe and completely lacking an anterior lateral tooth or angular projection. Male opercula not reaching lateral or distal margin of tympanal cavity, directed towards distomedial margin of tympanal cavity, apically broadly rounded, not meeting.

Wings. Fore wings with eight apical cells; medial veins and cubitus anterior vein meeting basal cell with their stems confluent; distance between radial and radiomedial crossveins equal to or slightly longer than between radiomedial and medial crossveins; fore wing infuscation absent on radial vein. Pterostigma slender, briefly reduced at tip and terminally acute; Radial crossvein oblique. Hind wings with siX apical cells; anal cell 3 short, reaching half the length of anal cell 2.

Legs. Fore femora bearing three developed black spines and a forth one (aborted) located at the base of the third spine. Primary spine strong and oblique; secondary spine sharp, oblique shorter than the primary spine; apical spine oblique, triangular, shorter than the secondary spine. Mid legs black. Hind legs similar to mid legs, with three lateral spurs on interior medial side and two on lateral eXterior side.

Abdomen. Oval shaped, sharply reduced posteriorly, as wide as mesonotum. Timbals broad, bearing three long ribs fused dorsally. Male stenite I flat and smooth; sternite VII about as long as wide.

Genitalia. Upper lobes of pygofer small, as long as wide; basal lobes undivided, shorter than upper lobe, 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, apically strongly divergent and sharp; dorsal of theca, originating closer to apeX of theca than its base, slightly longer than theca. Claspers smooth, parallel sided. Aedeagal basal plate in lateral view rightangled.
