( Figs. 11 , 63–67 )

Type material. Holotype: CHINA: Zhejiang Prov.: ɗ, Lishui City, Qingyuan County, Baishanzu, 1050 m, 4.V.2005, HU Jia-Yao & TANG Liang & ZHU Li-Long leg. Paratypes: CHINA: Zhejiang Prov.: 2ɗɗ, 3ΨΨ, same data as holotype; ɗ, Ψ, same locality as holotype, 19.VIII.2004, HU Jia-Yao & TANG Liang & ZHU Li-Long leg.

Description. Body length: 4.1–4.7 mm; forebody length: 2.5–2.8 mm.

Body ( Fig. 11 ) elongate, reddish brown, with coxae reddish yellow, antennal segments (except for two basal), maxillary palpi and legs (except for coxae) yellow.

Head suborbicular, slightly longer than broad (length/width = 1.02); postocular portion 2.10 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: 16.0: 5.5: 9.0: 8.0: 7.5: 7.0: 6.5: 6.0: 5.5: 5.5: 8.0; relative width of each segment from 1 to 11: 5.0: 3.5: 2.5: 2.5: 2.5: 2.5: 2.5: 2.5: 2.5:3.0: 3.0.

Pronotum convex and oval, longer than wide (length/width = 1.15), narrower (pronotum/head = 0.87) and shorter (pronotum/head = 0.98) than head; prosternum with strong longitudinal median carina extending to its anterior margin. Elytra as long as wide, distinctly shorter (elytra/pronotum = 0.86) and slightly narrower (elytra/pronotum = 0.98) than pronotum.

Abdomen without microsculpture.

Male. Seventh sternite ( Fig. 63 ) slightly triangularly emarginate in middle of posterior margin; 8th sternite ( Fig. 64 ) deeply triangularly excised in middle of posterior margin. Aedeagus ( Figs. 65–67 ) distinctly sclerotized; in dorsal view lateral sides of apical half of median lobe nearly straight and parallel, narrowed arcuately near apex, with a little projection at apex; dorso-lateral apophyses curved inward, slightly projecting inwards at middle in dorsal view, slightly dilated in middle 1/ 3 in lateral view, with apices not reaching apex of median lobe.

Female. Seventh and 8th sternites simple.

Remarks. Nazeris baishanzuensis is similar in appearance to N. yangdangensis , but can be distinguished from the latter by the following characters: male 7th sternite slightly emarginate at middle in posterior margin ( Fig. 63 ) (in N. yangdangensis slightly convex); median lobe of aedeagus with a little projection at apex in dorsal view ( Fig. 65 ) (in N. yangdangensis with V-shaped notch at apex of median lobe).

Distribution. China (Zhejiang Prov.).

Etymology. The species name is derived from the name of the type locality: Baishanzu Nature Reserve.
