description: 6. Nazeris tarandoides sp. nov.
(Figs. 1F, 2F, 8)
Type locality: China, Hubei Province, Eastern of Muyu Town, Wanjiagou.
Type material. Holotype male, CHINA: Hubei Province: Eastern of Muyu Town, Wanjiagou, altitude 900 m, 19.VII.1998, coll. Haisheng Zhou (IZ-CAS).
Measurements. BL: 5.1–5.7 mm; FL: 2.4–2.8 mm. HL: 0.90 mm; HW: 0.83 mm; PL: 0.84 mm; PW: 0.69 mm; EL: 0.70 mm; EW: 0.71 mm; ELL: 0.20 mm; POL: 0.50 mm.
Description. Body (Fig. 1F) elongate, dark brown; legs and antennae yellowish brown.
Head (Fig. 2F, 8A) weakly oblong, 1.08 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; eyes small and slightly protruding, postocular portion about 2.50 times as long as eye length.
Pronotum (Fig. 8A) oval, elongated, without distinct anterior and posterior angles, with anterior half slightly wider, 1.22 times as long as wide, slightly smaller than head, 0.93 times as long and 0.83 times as broad as head; punctation not umbilicate and about same as that on dorsal surface of head; longitudinal midline posteriorly with very narrow or without elevated impunctate band; interstices without microsculpture. Dense punctured depression near posterior middle margin but not so obviously.
Elytra (Fig. 8A) approximately as long as wide, distinctly shorter and slightly wider than pronotum, 0.83 times as long and 1.03 times as wide as pronotum; lateral sides expanded posteriorly with widest at posterior 1/3; hind wings reduced; punctation finer and slightly less dense than that of pronotum; interstices without microsculpture.
Abdomen covered with dense and coarse punctures on tergite III, dense and less coarse on tergites IV–VI, moderately dense and fine on tergite VII, sparse and fine on tergite VIII; interstices without microsculpture.
Male. Sternite VII (Fig. 8B) with posterior margin weakly prominent in the middle. Sternite VIII (Fig. 8C) with triangular posterior excision. Aedeagus (Figs. 8 D–8F) stout and well sclerotized; ventral process apically convex and with deep median incision in dorsal or ventral view; dorso-lateral apophyses short and stout, pair of sharply inward prominence near basal fourth in dorsal view, slightly extending beyond apex of ventral process.
Distribution and habitat data. The species is known only from Muyu Town, in western Hubei Province. The specimen was collected by sifting deciduous leaves at an altitude of 900 m.
Comparative notes. The new species is similar to N. parvincisus (Assing 2013: 9, figs. 32–37) from Shaanxi Province in habitus and aedeagal characters, but can be distinguished by the following characteristics: Sternite VII (Fig. 8B) with posterior margin weakly prominent at middle, but in N. parvincisus with small and indistinct concav- ity in the middle; its sternite VIII with deeper triangular posterior excision (Fig. 8C); ventral process with deeper median incision in dorsal view and without pair of small basal laminae (Fig. 8F); dorso-lateral apophyses with distinct inward processes near basal fourth in dorsal view (Fig. 8F).
Etymology. The specific epithet is derived from the Greek word tarand and the suffix - oides, to indicate the strong body form.
