Oteana omai sp. nov.

(figs 73–78)

Description

Body length. Male. 7.5 mm, n=1. Female. 8.7 mm (n=1).

Coloration

Anterior part of vertex and areolets dark brown, posterior corners of vertex stramineous. Frons irregularly testaceous, darkening towards frontoclypeal suture. Postclypeus testaceous, darkening towards anteclypeus; anteclypeus dark brown. Carinae of head yellowish. Pronotum with discoidal and ventral areas dark brown, carinae stramineous. Tegulae stramineous in dorsal aspect, slightly darker ventrally. Mesonotum in male with median portion (=area between carinae) light brown, carinae yellowish, lateral portions dark brown; without conspicuous longitudinal stripes. In female, mesonotum with areas between lateral carinae on each side lighter, yellowish, thus the mesonotum appears more distinctly longitudinally striped. Body and legs testaceous. Tegmen and wings hyaline, translucent, without any conspicuous pattern. Pterostigma distinct, light brown. Venation of tegmina yellowish brown, Y­vein and transversal veinlets slightly darker.

Proportions and carination of head and thorax as described for the genus; metatibiae laterally with 2–3 spines, otherwise as described for the genus.

Male genital complex (figs 73–78).

Genital segment (figs 73, 74) bilaterally asymmetrical, dorsal apical angle of subrectangular lobe on left side more strongly pronounced than on right side (fig. 74, arrow); subrectangular lobe in lateral aspect with a distinct ventral corner. Anal segment (figs 75, 76) bilaterally symmetrical, broadly ovate. Parameres (fig. 77) distally produced into a pointed tip, mediodorsal margin serrate. Aedeagus (fig. 78): shaft with 3 ventral spines (a1–a3) and a distinctly developed longitudinal ridge (a4?). Right lateral spine (a1) compressed, slender, curved laterad to the right side; median spines (a2, a3) short, toothlike. Apical spine of shaft (a5) long, terete, slender, curved laterobasad; subapical spine of shaft (a6) comparatively thin, curved more or less straight laterad to left side. Flagellum in repose not reaching base of shaft, distally bispinose..
