Oteana iaorana sp. nov.

(figs 16–21)

Description.

Body length.

Male. 6.2–6.3 mm; n= 2.

Coloration.

Head and thorax as in O. euphranor .. Legs stramineous, ventrally dark brown. Tegmina hyaline, translucent, proximally smoky brown, especially around the Y­vein. Costal vein proximad of junction with Y­vein dark brown over a short distance.

Proportions and carination of head and thorax as well as spinulation of hind legs as described for the genus, slightly larger than O. euphranor .

17, same, ventral aspect; 18, anal segment, dorsal aspect; 19, same, left lateral aspect; 20, left paramere,

maximal aspect; 21, aedeagus, ventral aspect. Scale bars equal 0.1 mm.

Male genital complex (figs 16–21)

Genital segment (figs 16, 17) bilaterally slightly asymmetrical: dorsolateral angle of subrectangular lobe acute on left side, on right side slightly longer, rounded. Anal segment (figs 18, 19) bilaterally symmetrical, broadly ovate. Parameres (fig. 20) distally produced into a blunt angle, mediodorsal margin serrate. Aedeagus (fig. 21): shaft with 3 ventral spines: right lateral spine (a1) inserting near base, compress, medially distinctly dilated, tapering towards tip, curved laterad to the right side; median spine (a2) inserting near base, short, thorn­like; left lateral spine (a3) of similar shape as spine a1, slightly more slender, strong, compressed, curved laterad to the right side, more or less parallel to right lateral spine; in one specimen with vestigial remnant of spine a4. Apical spine of shaft (a5) long, compress, taeniform, curved laterad to the left side; subapical spine of shaft (a6) ca. half the length of apical spine, compress, sinuate, directed laterad to the left side. Some slight variation among specimens in length of ventral shaft spines. Flagellum in repose nearly reaching base of shaft; distal flagellum spine (b1) present, not strongly sclerotized; in repose directed mediad.

Etymology

“Ia orana” is Tahitian for “hello”.

Distribution

Endemic to Tahiti (Tahitit Nui and Tahiti Iti).

Ecology

On native vegetation including Weinmannia parviflora (Cunoniaceae) , Metrosideros collina (Myrtaceae) , Myrsine spec . ( Myrsinaceae ). From 900– ca. 1400 m.

Remarks

O. iaorana differs from O. euphranor in body size (slightly larger) and particularly in the configuration of the male genitalia: genital segment slightly asymmetrical, and in the arrangement of ventral aedeagal spines.
