Oteana pouvana sp. nov.

(figs 54–59)

Description

Body length.

Male. 6.2–6.6 mm (n=3).

Coloration.

Coloration of head as described for O. euphranor , except for the postclypeus which is yellowish in O. pouvana . Pro­ and mesonotum as in O. euphranor . Tegmina with venation stramineous in proximal two­thirds, dark brown in distal third. Costal vein and pterostigma dark brown.

Spinulation of hind legs as described for the genus, with some variation observed: one specimen displayed 4 and 2 spines, respectively, laterally on the hind tibia.

Male genital complex (54–59).

Genital segment (figs 54, 55) bilaterally slightly asymmetrical: dorsolateral angle of subrectangular lobe acute on left side, rounded on right side. Anal segment (figs 56, 57) bilaterally symmetrical, broadly ovate. Parameres (fig. 58) distally produced into a blunt angle directed mediad, mediodorsal margin serrate. Aedeagus (fig. 59): shaft with 3 ventral spines: right lateral spine (a1) inserting near base of shaft, compressed, taeniform, widest at midlength, rapidly tapering, dorsolateral margin irregularly sinuate, twisted at base, curved laterad to right side. Median spine (a2) inserting near base, short, thorn­like; left lateral spine (a3) inserting with a wide base, compressed, taeniform, curved laterad to right side, more or less parallel to right lateral spine. Apical spine of shaft (a5) very long, compressed, taeniform, bent at ca. 1/5 of its total length in a nearly right angle, in repose directed laterad to the left side. Subapical spine of shaft (a6) arising from a narrow base, ca. half as long as apical spine of shaft, but of similar shape and direction. Flagellum in repose not reaching base of shaft, distal flagellum spine (b1) present, not strongly sclerotized, in repose directed straight mediad. Sclerotized ridge of flagellum with ventromedian margin irregularly serrate.

Etymology

Named in honor of Pouvanaa a Oopa, proponent of Polynesian autonomy and first Polynesian to win a seat in the French Chamber of Deputies, in 1949.

Distribution

Endemic to Tahiti (Tahiti Nui).

Ecology

On native vegetation including Weinmannia parviflora (Cunoniaceae) , Metrosideros collina (Myrtaceae) , Myrsine spec . ( Myrsinaceae ); 600–1400 m.

Remarks

Oteana pouvana resembles O. iaorana in the aedeagus spine configuration, but differs from this species by the long and taeniform apical shaft spine, as well as in the distal flagellum spine, which is much more strongly pronounced in O. iarorana .
