Type material. Holotype: CHINA: Zhejiang Prov.: ɗ, Wuyi County, Niutoushan, 400–600 m, 3.VIII.2006, LI Jin-Wen & SHEN Shan-Jia leg. Paratypes: CHINA: Zhejiang Prov.: 8ɗɗ, 2ΨΨ, same data as holotype; 8ɗɗ, 4ΨΨ, Wuyi County, Niutoushan, 500–700 m, 4.VIII.2006, LI Jin-Wen & SHEN Shan-Jia leg.
Description. Body length: 4.5–4.9 mm; forebody length: 2.6–2.7 mm.
Body ( Fig. 4 View FIGURES 1 – 12 ) elongate, brown, with labrum, coxae and two basal antennal segments reddish yellow; the remaining antennal segments, maxillary palpi and legs except for coxae yellow.
Head suborbicular, slightly longer than broad (length/width = 1.06); postocular portion twice as long as eye length; on disc intervals between punctures flat, not raised like carinae. Antennae slender, extending to basal 1/3 of pronotum; relative length of each segment from 1 to 11: 32.0: 12.0: 20.0: 15.0: 15.0: 14.0: 14.0: 14.0: 14.0: 13.0: 17.0; relative width of each segment from 1 to 11: 10.0: 7.0: 5.0: 5.0: 5.0: 5.0: 5.0: 5.0: 5.0:6.0: 7.0.
Pronotum convex and oval, longer than wide (length/width = 1.19), narrower (pronotum/head = 0.88) than and as long as head; prosternum with strong longitudinal median carina not reaching its anterior margin. Elytra slightly shorter than wide (length/width = 0.97), distinctly shorter (elytra/pronotum = 0.82) than and as wide as pronotum.
Third tergite of abdomen without microsculpture, 4th and 5th tergite with very faint microsculpture, 6th tergite with mesh-like microsculpture reaching posterior margin, third to 6th sternite without microsculpture, 7th sternite with mesh-like microsculpture reaching posterior margin.
Male. Seventh sternite ( Fig. 28 View FIGURES 28 – 32 ) simply rounded in middle of posterior margin; 8th sternite ( Fig. 29 View FIGURES 28 – 32 ) deeply Vshaped excised in middle of posterior margin. Aedeagus ( Figs. 30–32 View FIGURES 28 – 32 ) distinctly sclerotized; median lobe in dorsal view widened in apical 1/3 and with triangular extension near apex; dorso-lateral apophyses long and narrow, slightly curved inwards, gradually narrowed from base to middle and then widened apically, distinctly widened ventrad near apex in lateral view, extending beyond apex of median lobe.
Female. Seventh and 8th sternites simple.
Remarks. Nazeris niutoushanus is similar in appearance to N. nomurai Watanabe, 2000 from Yunnan Province, but can be easily distinguished from the latter by the following characters: male 7th sternite simply rounded at middle of posterior margin ( Fig. 28 View FIGURES 28 – 32 ) (in N. nomurai slightly emarginate); 8th sternite with V-shaped emargination ( Fig. 29 View FIGURES 28 – 32 ) (in N. nomurai the emargination is wider and rounder); dorso-lateral apophyses of aedeagus nearly straight in lateral view ( Fig. 31 View FIGURES 28 – 32 ) (in N. nomurai curved ventrad).
Distribution. China (Zhejiang Prov.).
Etymology. The species name was derived from the name of the type locality: Mt. Niutoushan Nature Reserve.
