Oteana mato
sp. nov.
(figs 35–40)
Description
Body length.
Male
. 5.0–
5.7 mm
(n=9).
Coloration
Coloration of head generally as in
O
. euphranor
, but postclypeus in upper half yellowishorange, with a dark brown fringe towards frons; postclypeus in lower half and anteclypeus dark brown. Coloration otherwise as described for
O
. euphranor
.
Proportions and carination of head and thorax as well as spinulation of hind legs as described for the genus.
Male
genital complex (figs 35–40).
Genital segment (figs 35, 36) bilaterally asymmetrical, laterodorsal angle of subrectangular process produced into an acute tip on left side (fig. 35, arrow), rounded on right side. Medioventral process dorsally ridged, in lateral aspect ventral margin distinctly serrate. Anal segment (fig 37, 38) symmetrical, ovate. Parameres (figs. 39) with distal portion in lateral aspect apically rounded, dorsal margin serrate, with an acute tip directed mediad (fig. 39 a, b, arrow). Aedeagus (figs 7, 40): shaft dorsally with a small, inconspicuous, earshaped protrusion, ventrally with 4 spines: right lateral spine (a1) arising from joint base with right median spine (a2). Right lateral spine long, terete, slender throughout, curved laterad to right side; median right spine short, erect. Median left spine (a3) and left lateral spine (a4) also arising from a common base: median left spine stout, rapidly tapering, erect; left lateral spine slender, filiform, directed mediad towards tip of median left spine. Apcial spine of shaft (a5) long, terete, with a distinct “knee” near its base (fig. 40, arrow), curved semicircularly laterobasad to the left side. Subapical spine (a6) ca. 1/3 the length of apical spine, slender and terete at base, distally compressed and broadened, sinuate, bent laterad to the left side, tip pointing apically. Flagellum in repose not reaching base of shaft; distal flagellum spine (b1) directed mediad. Sclerotized flagellum ridge produced into a sharp edge at midlength of flagellum.
Etymology
Named for a refuge hut on the Mt.
Aorai
trail, Fare
Mato

Oteana mato
sp. nov.
, holotype. Male genitalia. 35, genital segment, left lateral aspect; 36, same, ventral aspect; 37, anal segment, dorsal aspect; 38, same, left lateral aspect; 39, left paramere: a, maximal aspect, b, caudal aspect; 40, aedeagus, ventral aspect. Scale bars equal 0.1 mm.
Remarks
Oteana mato
differs from all other
Oteana
species by the coloration of the postclypeus (upper half yellowishorange) and particularly by the configuration of the ventral, apical, and subapical aedeagus shaft spines.
