Hoch, Hannelore, 2006, New Cixiidae from Eastern Polynesia: Oteana gen. nov. and Manurevana gen. nov. (Hemiptera: Fulgoromorpha), Zootaxa 1209, pp. 1-47 : 15-16

Oteana aorai sp. nov.

(figs 29–34)

Description

Body length.

Male. 6.8 mm (n=1). Female unknown.

Coloration

Head stramineous, except for area of vertex, areolets, and area enclosed by frontal carina fork, these dark brown. Pronotum as in O. euphranor , mesonotum with areas enclosed by lateral carinae on each side stramineous, distinctly contrasting, resulting in longitudinal stripes. Tegmina hyaline, translucent, without conspicuous markings, pterostigma distinctly dark; venation in distal third dark brown.

Proportions and carination of head and thorax as described for the genus. Metatibiae laterally with 4 small spines. Spinulation of hind legs otherwise as described for the genus.

Male genital complex (figs 29–34).

Genital segment (figs 29, 30) bilaterally asymmetrical: laterodorsal angle of subrectangular process with acute tip on left side, rounded on right side. Anal segment (figs 31, 32) asymmetrical, elongately ovate. Parameres (fig. 33): distal portion produced into a broad lobe, apically rounded. Aedeagus (fig. 34): shaft dorsally with an ear­shaped protrusion near apex (fig. 34, arrow), ventrally with 2 spines: right lateral spine (a1) inserting near shaft base, compressed, taeniform, curved laterad to right side. Left ventral spine (a2) vestigial, tooth­like, inserting mediad of base of right lateral spine. Apical spine of shaft (a5) more or less compressed, bent in a ca. 90º angle at 1/3 of its length, directed laterad to left side, slightly sinuate; subapical spine of shaft (a6) long, slender, terete, bent at midlength, directed laterobasad to left side. Flagellum in repose not reaching base of shaft, distal flagellum spine (b1) short, stout, directed mediad, and a short, inconspicuous spine (b2) arising from sclerotized ridge at midlength of flagellum (fig. 34, arrow).

Etymology

Named for its type locality, Mt. Aorai , near Papeete, Tahiti. Distribution

Endemic to Tahiti (Tahiti Nui: Mt. Aorai ).

Ecology

On native vegetation including Weinmannia parviflora (Cunoniaceae) , Metrosideros collina (Myrtaceae) , Myrsine spec . ( Myrsinaceae ). Between 600– 900 m.

Remarks

Oteana aorai is easily distinguished from all other Oteana species by its light body coloration and the configuration of the aedeagal shaft spines.
