Nazeris zhaotiexiongi Hu & Li , sp. n.

( Figs. 28–33 )

Type material. Holotype: CHINA: male: " China: Zhejiang Province, Zhuji City, Wuxie Parkland , mixed forest, leaf litter, sifted, 100–300 m, 9-VIII-2014, Tie-Xiong Zhao leg." ( SNUC) . Paratypes: 2 males, 5 females, same data as holotype ; 6 males, 4 females, " China: Zhejiang Province, Zhuji City, Sanjiejian , leaf litter, sifted, 1000 m, 6.VI.2016, Tie-Xiong Zhao leg." ( SNUC) .

Description. Body length 4.9–5.4 mm; forebody length 2.4–2.6 mm.

Body ( Fig. 28 ) reddish brown to dark brown; antennae and legs yellowish brown.

Head as long as wide; punctation dense and coarse, non-umbilicate, interstices without microsculpture; postocular portion 1.96 times as long as eye length.

Pronotum 1.14 times as long as wide, 0.88 times as broad and as long as head; punctation as dense and as coarse as that of head; midline posteriorly with short and very narrow impunctate elevation; interstices without microsculpture. Elytra 0.67 times as long as wide, 0.61 times as long and 1.04 times as broad as pronotum; punctation as dense and slightly coarser than that of pronotum; interstices without microsculpture.

Abdomen with punctation dense and rather coarse on tergites III–V, dense and less coarse on tergite VI, moderately dense and fine on tergites VII–VIII; interstices with rather fine microsculpture on apical half of tergites VII and VIII.

Male. Sternite VII ( Fig. 29 ) with posterior margin truncate at middle. Sternite VIII ( Fig. 30 ) with V-shaped posterior excision. Aedeagus ( Figs. 31–33 ) with ventral process broad and long, widened near middle, shallowly concave at apex in ventral view; dorso-lateral apophyses distinctly widened near basal third in ventral and lateral view, extending slightly beyond apex of ventral process.

Distribution and habitat data. The species was found from two localities in north Zhejiang. The specimens were collected by sifting leaf litter at altitudes of 100–1000 m.

Comparative notes. The new species is similar to N. shenshanjiai in general appearance, but can be separated by the deeper excision of male sternite VIII ( Fig. 30 ), by the much narrower ventral process of the aedeagus and the slightly longer dorso-lateral apophyses ( Figs. 31–33 ).

Etymology. The species is named in honor of Tie-Xiong Zhao, collector of the new species.
