Oteana gemellar (Fennah) comb. nov.

(figs 85–90)

Oliarus gemellar Fennah, 1958: 129

Supplementary description.

Body length.

Male. 6.0 mm (n=1). Female. 6.5 – 6.9 mm (n=3).

Proportions and carination of head and thorax, venation of tegmina as well as spinulation of hind tibiae as described for the genus.

Coloration

Area of vertex and areolets dark brown. Frons stramineous, slightly darker towards vertex, medially with a distinct short dark brown band just above frontoclypeal suture. Anteclypeus and postclypeus in lower part dark brown, lighter brown towards frontoclypeal suture. Carinae of head and fenestrae stramineous. Pronotum with discoidal and ventral areas brownish, posterior margins and carinae stramineous. Mesonotum dark brown, longitudinal carinae, posterior margin and tip stramineous. Mesonotum laterally of outer carinae with a suffusely light brown spot. Body dark brown, legs stramineous. Tegmina hyaline, translucent, without any conspicuous color pattern. Venation stramineous, only slightly darker distally. Pterostigma light brown as well as costal vein, the latter only slightly darker around distal margin.

Male genital complex (figs 85–90).

Genital segment (figs 85, 86) bilaterally asymmetrical, laterodorsal angle of subrectangular lobe acute on left side, rounded on right side; medioventral process short, stout, dorsally ridged. Anal segment (figs 87, 88) bilaterally symmetrical, broadly ovate. Parameres (fig. 89) with distal portion subapically broadened, tapering apically into an acute tip directed mediobasad, mediodorsal margin slightly serrate. Aedeagus (fig. 90): shaft with 2 ventral and one apical spines: right lateral ventral spine (a1) arising at midlength of shaft, strong, terete, bent at ca. ½ its length in a more or less right angle to right side, its tip pointing laterobasad. Left spine (a3) arising slightly distad of base of right lateral spine, slender, curved at ca. 1/3 its length in a more or less right angle to left side, its tip pointing laterad to left side. Apical spine of shaft (a5) arising from a triangular base on apex of shaft, long, slender, distally tapering, curved laterobasad to the left side. Flagellum in repose not reaching base of shaft, distal flagellum spine strong, stout, tip subacute; dorsomedian lobe of flagellum produced into a second strong, apically blunt spinose process, in repose directed mediobasad. Phallotreme wide (fig. 90, arrow), flanked by the two distal flagellum spines.

Distribution

Endemic to the Cook Islands: Rarotonga.

Ecology

Unknown.

Remarks

O. gemellar can be distinguished from the Society Islands Oteana species by the absence of the subapical aedeagal shaft spine (a6).
