Type material. Holotype: CHINA: male: "China: Guangxi, Huanjiang, Jiuwan Mt. , Yangmeiao , 25°12'22.15''N, 108°40'32.01''E, 1250 m, 8.v.2021, Tang, Peng, Cai & Song leg. [ḞƱflữƌfffiƜêDzḏ]" ( SNUC) GoogleMaps . Paratypes: 2 females, same data as holotype GoogleMaps ; 1 male, 2 females, same data, except " 23.iv.2021 " GoogleMaps ; 5 females, same data, except "Liuzhou city, Jiuwan Shan N. R., Yangmei'ao, 25°11'42''N, 108°38'51''E, 1200 m, 24–26.vii.2015, Li & Zhao leg." ( SNUC) GoogleMaps .

Diagnosis. Body dark brown, large in size; head with umbilicate punctation; abdominal tergites lacking microsculpture; aedeagal ventral process distinctly narrowed near apex in ventral and lateral view; dorso-lateral apophyses gradually narrowed apicad, not reaching apex of ventral process.

Description. Body length 6.8–7.6 mm; forebody length 3.4–3.5 mm.

Body ( Fig. 1C View FIGURE 1 ) dark brown; antennae and legs yellowish brown.

Head ( Fig. 2C View FIGURE 2 ) 1.00–1.11 times as long as wide; punctation very dense, moderately coarse, distinctly umbilicate and partly confluent, interstices lacking microsculpture; postocular portion approximately 1.6–1.8 times as long as eye length.

Pronotum ( Fig. 2C View FIGURE 2 ) 1.17–1.22 times as long as wide, 1.00–1.10 times as long and 0.89–0.95 times as broad as head; punctation non-umbilicate, moderately dense and as coarse as that of head; midline posteriorly with short and narrow impunctate elevation; interstices lacking microsculpture.

Elytra ( Fig. 2C View FIGURE 2 ) 0.65–0.68 times as long as wide, 0.53–0.55 times as long and 0.94–1.00 times as dense as pronotum; punctation as dense and coarse as that of pronotum; interstices lacking 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 lacking microsculpture.

Male. Sternite VII ( Fig. 5A View FIGURE 5 ) with posterior margin truncate at middle. Sternite VIII ( Fig. 5B View FIGURE 5 ) with triangular posterior excision. Aedeagus ( Figs 5C–F View FIGURE 5 ) well sclerotized; ventral process long, distinctly narrowed near apex in ventral and lateral view; dorso-lateral apophyses very strong, gradually narrowed apicad in ventral view, not reaching apex of ventral process.

Distribution and habitat data. The species is known only from Jiuwan Mt. in northern Guangxi. The specimens were collected by sifting leaf litter at altitudes of 1,200 –1,250 m.

Comparative notes. The new species is distinguished from all the known species of Nazeris from Guangxi and adjacent area by the distinctive shape of the aedeagus: ventral process distinctly narrowed near apex in ventral and lateral view ( Figs 5C–F View FIGURE 5 ); dorso-lateral apophyses gradually narrowed apicad in ventral view ( Figs 5C, D View FIGURE 5 ).

Etymology. The specific epithet is derived from the name of the type locality: Yangmei'ao.
