Oteana ata
sp. nov.
(figs 41–46)
Description.
Body length.
Male
.
5.3 – 5.4 mm
(n=3).
Coloration as described for
O
. euphranor
as well as proportions and carination of head and thorax. Metatibiae laterally with 1–2 small spines (variable within individuals), spinulation of hind legs otherwise as described for the genus.
Male
genital complex (figs 41–46).
Genital segment (figs 41, 42) nearly bilaterally symmetrical: laterodorsal angle of subrectangular lobes rounded on both sides; subrectangular process on right side slightly more pronounced than on left side. Anal segment (figs 43, 44) symmetrical, elongately ovate. Parameres (fig. 45) with distal part produced into a stout acute tip directed mediad. Aedeagus (fig. 46): shaft ventrally with 2–3 spines: in specimens with 3 ventral shaft spines: median spine (a2+a3?) more or less strongly developed, apically medially truncate, slightly incised; right lateral (a1) and left lateral spine (a4) feebly developed. In specimens with 2 ventral shaft spines, left spine strongly developed, apically acute, right spine feebly developed, as long as left spine. Apical spine of shaft (a5) long, terete, slender throughout, bent in a ca. 90º angle at midlength, in repose directed laterobasad to left side. Subapical spine of shaft (a6) slender at base, nearly straight directed laterodorsad to left side. Flagellum in repose not reaching base of shaft, distal flagellum spine (b1) strongly pronounced, directed straight basad. Sclerotized flagellum ridge produced into a strong, stout spine (b2) directed laterobasad to the left side.
