Nazeris jiulongshanus Hu, Li & Zhao, sp. nov.

(Figs. 9, 53–57)

Type material. Holotype: CHINA: Zhejiang Prov.: ɗ, Suichang County, Jiulongshan, 500–700 m, 31.VII.2006, LI Jin-Wen & SHEN Shan-Jia leg.. Paratypes: CHINA: Zhejiang Prov.: Ψ, same data as holotype.

Description. Body length: 4.6–4.8 mm; forebody length: 2.6–2.9 mm.

Body (Fig. 9) elongate, reddish brown, with labrum and coxae reddish yellow, antennal segments (except for two basal ones), maxillary palpi and legs (except for coxae) yellow.

Head suborbicular, slightly longer than broad (length/width = 1.02); postocular portion 2.05 times as long as eye length; on disc intervals between punctures flat, not raised like carinae. Antennae slender, extending to middle of pronotum; relative length of each segment from 1 to 11: 31.0: 12.0: 19.5: 15.0: 14.0: 13.5: 12.5: 12.0: 12.0: 10.0: 16.0; relative width of each segment from 1 to 11: 11.0: 7.0: 5.5: 5.5: 5.5: 5.5: 5.5: 5.5: 5.5: 6.5: 7.5.

Pronotum convex and oval, longer than wide (length/width = 1.17), narrower (pronotum/head = 0.88) and longer (pronotum/head =1.01) than head; prosternum with strong longitudinal median carina not reaching its anterior margin. Elytra slightly shorter than wide (length/width = 0.96), distinctly shorter (elytra/pronotum = 0.81) and slightly narrower (elytra/pronotum = 0.99) than pronotum.

Abdomen without microsculpture.

Male. Seventh sternite (Fig. 53) simply rounded in middle of posterior margin; 8th sternite (Fig. 54) triangularly excised in middle of posterior margin. Aedeagus (Figs. 55–57) distinctly sclerotized; median lobe long, in dorsal view arcuately widened near apex, apex acute, in lateral view gradually narrowed apicad and slightly arcuated dorsad near apex; dorso-lateral apophyses in dorsal view each with a small inward projection at apical 1/3, in lateral view arcuated dorsad at apical 1/3, not reaching apex of median lobe.

Female. Seventh and 8th sternites simple.

Remarks. Nazeris jiulongshanus resembles N. yandangensis but can be easily distinguished from the latter by the following characters: the median carina of prosternum does not reach the anterior margin (in N. yandangensis the carina extends to the anterior margin); apex of median lobe of aedeagus acute in dorsal view (Fig. 55) (in N. yandangensis notched at apex).

Distribution. China (Zhejiang Prov.).

Etymology. The specific name is derived from the name of the type locality: Mt. Jiulongshan Nature Reserve.
