1. Nazeris lushanensis View in CoL sp. nov.
( Figs. 1A View FIGURE 1 , 2A View FIGURE 2 , 3 View FIGURE 3 )
Type locality: China, Sichuan Province, Northeast of Lushan County, Longmencun .
Type material. Holotype male, CHINA: Sichuan Province: Northeast of Lushan County, Longmencun , 15.X.2005, coll. Haifeng Chen ( IZ-CAS).
Measurements. BL: 4.7 mm; FL: 2.4 mm. HL: 0.83 mm; HW: 0.77 mm; PL: 0.77 mm; PW: 0.63 mm; EL: 0.67 mm; EW: 0.62 mm; ELL: 0.23 mm; POL: 0.38 mm.
Description. Body ( Fig. 1A View FIGURE 1 ) elongate, nearly black; legs and antennae yellowish brown.
Head ( Figs. 2A View FIGURE 2 , 3A View FIGURE 3 ) moderately oblong, 1.08 times as long as wide; punctation in middle of head dense and coarse, umbilicate punctures distinct in middle of head and partly confluent on vertex, intervals between punctures smaller than diameters of punctures; umbilicate punctures present vaguely and sparsely on posterior margin of head; interstices without microsculpture; eyes small and protruding, postocular portion approximately 1.65 times as long as eye length.
Pronotum ( Fig. 3A View FIGURE 3 ) oval, elongated, lacking distinct anterior and posterior angles, with posterior half slightly narrowed, 1.22 times as long as wide, slightly smaller than head, 0.93 times as long and 0.82 times as broad as head; punctation not umbilicate, moderately dense and as coarse as that of head; longitudinal midline posteriorly with very short and narrowly elevated impunctate band; interstices without microsculpture. Dense punctured depression near posterior middle margin.
Elytra ( Fig. 3A View FIGURE 3 ) 1.08 times as long as wide, elytral length shorter than pronotum, 0.87 times as long and approximately as wide as pronotum; lateral sides expanded posteriorly with widest at posterior 1/3; hind wings reduced; punctation as dense as, less coarse than that of pronotum; interstices without microsculpture.
Abdomen covered with dense and coarse punctures on tergites III–V, dense and less coarse on tergite VI, sparse and fine on tergites VII–VIII; interstices without microsculpture.
Male. Sternite VII ( Fig. 3B View FIGURE 3 ) with posterior margin distinctly convex at middle. Sternite VIII ( Fig. 3C View FIGURE 3 ) with triangular posterior excision. Aedeagus ( Figs. 3 View FIGURE 3 D–3F) strongly sclerotized; ventral process cone-shaped, broadly constricted in the middle in ventral view, with narrowly round apex; dorso-lateral apophyses moderately long, pair of inward processes near apical 4/ 5 in dorsal or ventral view, extending slightly beyond apex of ventral process.
Distribution. The species is known only from Lushan County in the middle Sichuan Province.
Comparative notes. The new species is similar to N. peniculatus Assing (Assing 2013: 154, Figs. 124–129) in habitus and aedeagal characters, but can be distinguished from N. peniculatus by the following combination of characters: its sternite VII ( Fig. 3B View FIGURE 3 ) with posterior margin distinctly prominent at middle, while N. peniculatus with posterior margin concaved; its triangular posterior excision of male sternite VIII shallower ( Fig. 3C View FIGURE 3 ), but N. peniculatus with deep and narrowly U-shaped posterior excision; apex of wider ventral process of aedeagus rounder in ventral view ( Fig. 3D View FIGURE 3 ).
Etymology. The specific epithet is derived from the Chinese name (Pinyin) of the type locality, Lushan County, Sichuan Province.
