2. Nazeris cuscutus View in CoL sp. nov.
( Figs. 1B View FIGURE 1 , 2B View FIGURE 2 , 4 View FIGURE 4 )
Type locality: China, Sichuan Province, Northern part of Pengzhou City, Longmenshan .
Type material. Holotype male, CHINA: Sichuan Province: Northern part of Pengzhou City, Longmenshan , 24.VII.2001, coll. Hongzhang Zhou ( IZ-CAS).
Measurements. BL: 5.4 mm; FL: 2.7 mm. HL: 0.92 mm; HW: 0.87 mm; PL: 0.82 mm; PW: 0.72 mm; EL: 0.70 mm; EW: 0.75 mm; ELL: 0.23 mm; POL: 0.47 mm.
Description. Body ( Fig. 1B View FIGURE 1 ) elongate and dark brown; legs and antennae yellowish brown.
Head ( Fig. 2B View FIGURE 2 , 4A View FIGURE 4 ) weakly oblong, 1.06 times as long as wide; punctation of head very dense and moderately coarse, punctation not umbilicate and not confluent on vertex, with relatively uniform distribution; distance between punctures bigger than diameters of punctures; interstices without microsculpture; with small and protruding eyes, postocular portion approximately 2.04 times as long as eye length.
Pronotum ( Fig. 4A View FIGURE 4 ) oval, elongated, without distinct anterior and posterior angles, with anterior half slightly wider, 1.14 times as long as wide, smaller than head, 0.89 times as long and 0.83 times as broad as head; punctation not umbilicate and similar to that of head; longitudinal midline posteriorly with very short and narrowly elevated impunctate band; interstices without microsculpture. Densely punctured depression near posterior middle margin.
Elytra ( Fig. 4A View FIGURE 4 ) 0.93 times as long as wide, distinctly shorter and slightly wider than pronotum, 0.85 times as long and 1.04 times as wide as pronotum; lateral sides expanded posteriorly, widest at posterior 1/3; hind wings reduced; punctation as dense and slightly coarser than that of pronotum; interstices without microsculpture.
Abdomen with punctation dense and coarse on tergites III–VI, sparse and fine on tergites VII–VIII; interstices without microsculpture.
Male. Sternite VII ( Fig. 4B View FIGURE 4 ) with posterior margin distinctly prominent in the middle. Sternite VIII ( Fig. 4C View FIGURE 4 ) with a broad V-shaped excision on posterior margin. Aedeagus ( Figs. 4 View FIGURE 4 D–4F) strongly sclerotized; ventral process short, with distinctly bifurcate at apex in ventral or dorsal view, and with pair of small basal laminae dorsally; dorsolateral apophyses stubby, distinctly widened in apical half in ventral view, extending slightly beyond apex of ventral process.
Distribution and habitat data. The species is known only from Pengzhou City, in northern Sichuan Province. The specimen was collected by sifting leaf litter at an altitude of 1380 m.
Comparative notes. The new species is similar to Nazeris furcatus Hu, Li & Zhao (Hu, Li & Zhao 2011: 3, figs. 18–22) from Zhejiang Province, but can be separated by the following combination of characters: Sternite VII ( Fig. 4B View FIGURE 4 ) with posterior margin distinctly prominent at middle, but in N. furcatus with posterior margin shallowly concave in the middle; ventral process with shallower median incision in dorsal view; dorso-lateral apophyses wider than N. furcatus in ventral view.
Etymology. The specific epithet is derived from the new Latin word cuscuta, originally from Arabic language and here without special indication.
