Diagnosis.
Body dark reddish brown; head with non-umbilicate punctation; abdominal tergites lacking microsculpture; aedeagal ventral process very long, with acute apex in ventral view; dorso-lateral apophyses with narrow apex in ventral view, not reaching apex of ventral process.
Description.
Body length
4.1–5.2 mm
, forebody length
2.4–2.6 mm
.
Body (
Fig. 1E
) dark reddish brown; antennae and legs yellowish brown.
Head (
Fig. 2E
) 1.03–1.06 times as long as wide; punctation moderately dense, very coarse, non-umbilicate and not confluent, interstices lacking microsculpture; posterior portion 1.7–1.9 times as long as eye length.
Pronotum (
Fig. 2E
) 1.06–1.15 times as long as wide, 0.89–0.95 times as long and 0.84–0.86 times as broad as head; punctation similar to that of head; midline posterior with short and very narrow impunctate elevation; interstices lacking microsculpture.
Elytra (
Fig. 2E
) 0.58–0.68 times as long as wide, 0.53–0.65 times as long and 1.03–1.09 times as broad as pronotum; punctation similar to that of pronotum; interstices lacking microsculpture.
Abdomen (
Fig. 1E
) with punctation dense and rather coarse on tergites III–IV, dense and less coarse on tergites V–VI, moderately dense and fine on tergites VII–VIII; interstices lacking microsculpture.
Male.
Sternite VII (
Fig. 7A
) with posterior margin shallowly emarginated in the middle, and with shallow postero-median impression, on either side of this impression with a tuft of dense dark setae. Sternite VIII (
Fig. 7B
) with V-shaped posterior excision.Aedeagus (
Figs 7C–F
) with ventral process very long and narrow, with acute apex in ventral view; dorso-lateral apophyses slender, slightly curved near apex in ventral view, not reaching apex of ventral process.
Distribution and habitat.
The species is known from Gyirong County in southern
Xizang
(
Fig. 10K
). The specimen was collected by sifting leaf litter at altitudes of
3000–4100 m
.
Comparative notes.
This species is similar to
N. hirsutiventris
Assing,
2014
in general appearance and aedeagus characters, but can be separated by the round apex of dorso-lateral apophyses (
Figs 7C, D
), and the narrower apex of ventral process of aedeagus in lateral view (
Figs 7E, F
).
Etymology.
The specific epithet
‘
gladius
(sword)’ is a Latin noun referring to the special ventral process of aedeagus.
