Nazeris yuyimingi Hu & Qiao View in CoL , sp. n.

(Figs 4, 25–29)

Type material. Holotype: CHINA: GoogleMaps male, ‘ China: Guangxi, Xing'an County, Mao'ershan   GoogleMaps , 25°53'7''N, 110°29'14''E, beech forest, mixed leaf litter, humus, sifted, 1143 m, 31.VII.2014, Peng, Song, Yu & Yan leg.’ (SNUC).

Description. Body length 6.1 mm; forebody length 3.3 mm.

Body (Fig. 4) dark brown; antennae and legs yellowish brown.

Head ( Fig. 25 View FIGURES 25–29 ) approximately as long as wide; punctation very dense, moderately coarse, distinctly umbilicate and partly confluent, interstices lacking microsculpture; postocular portion approximately 1.8 times as long as eye length.

Pronotum ( Fig. 25 View FIGURES 25–29 ) 1.18 times as long as wide, 1.05 times as long and 0.90 times as broad as head; punctation non-umbilicate, moderately dense and as coarse as that of head; midline posteriorly with very short and narrow impunctate elevation; interstices lacking microsculpture.

Elytra ( Fig. 25 View FIGURES 25–29 ) 0.61 times as long as wide, 0.53 times as long and as broad as pronotum; punctation as dense as, and less coarse than that of pronotum; interstices lacking microsculpture.

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

Male. Sternite VII ( Fig. 26 View FIGURES 25–29 ) with posterior margin shallowly concave in the middle. Sternite VIII ( Fig. 27 View FIGURES 25–29 ) with V-shaped posterior excision. Aedeagus ( Figs 28, 29 View FIGURES 25–29 ) moderately sclerotized; ventral process long, dorsal parts slightly widened near middle and apex in ventral view, with pair of triangular basal laminae ventrally; dorso-lateral apophyses slender, slightly widened near apex in ventral view, extending slightly beyond apex of ventral process.

Distribution and habitat data. The species is known only from Mao'ershan in northeast Guangxi. The specimen was collected by sifting leaf litter at an altitude of 1143 m.

Comparative notes. The new species is similar in general appearance and aedeagal characters to N. chenyanae Hu & Li (Hu & Li 2017: 340, Figs 25–29 ), but can be separated by the shallowly concaved male sternite VII ( Fig. 26 View FIGURES 25–29 ), and by the narrower ventral process and the wider apex of dorso-lateral apophyses of aedeagus ( Fig. 28 View FIGURES 25–29 ).

Etymology. The species is named in honor of Yi-Ming Yu, who collected some of the type specimens.
