Body length: 4.5���4.9 mm; forebody length: 2.6���2.7 mm. Body (Fig. 4) elongate, brown, with labrum, coxae and two basal antennal segments reddish yellow; the remaining antennal segments, maxillary palpi and legs except for coxae yellow. Head suborbicular, slightly longer than broad (length/width = 1.06); postocular portion twice as long as eye length; on disc intervals between punctures flat, not raised like carinae. Antennae slender, extending to basal 1 / 3 of pronotum; relative length of each segment from 1 to 11: 32.0: 12.0: 20.0: 15.0: 15.0: 14.0: 14.0: 14.0: 14.0: 13.0: 17.0; relative width of each segment from 1 to 11: 10.0: 7.0: 5.0: 5.0: 5.0: 5.0: 5.0: 5.0: 5.0:6.0: 7.0. Pronotum convex and oval, longer than wide (length/width = 1.19), narrower (pronotum/head = 0.88) than and as long as head; prosternum with strong longitudinal median carina not reaching its anterior margin. Elytra slightly shorter than wide (length/width = 0.97), distinctly shorter (elytra/pronotum = 0.82) than and as wide as pronotum. Third tergite of abdomen without microsculpture, 4 th and 5 th tergite with very faint microsculpture, 6 th tergite with mesh-like microsculpture reaching posterior margin, third to 6 th sternite without microsculpture, 7 th sternite with mesh-like microsculpture reaching posterior margin. Male. Seventh sternite (Fig. 28) simply rounded in middle of posterior margin; 8 th sternite (Fig. 29) deeply Vshaped excised in middle of posterior margin. Aedeagus (Figs. 30���32) distinctly sclerotized; median lobe in dorsal view widened in apical 1 / 3 and with triangular extension near apex; dorso-lateral apophyses long and narrow, slightly curved inwards, gradually narrowed from base to middle and then widened apically, distinctly widened ventrad near apex in lateral view, extending beyond apex of median lobe. Female. Seventh and 8 th sternites simple. Remarks. Nazeris niutoushanus is similar in appearance to N. nomurai Watanabe, 2000 from Yunnan Province, but can be easily distinguished from the latter by the following characters: male 7 th sternite simply rounded at middle of posterior margin (Fig. 28) (in N. nomurai slightly emarginate); 8 th sternite with V-shaped emargination (Fig. 29) (in N. nomurai the emargination is wider and rounder); dorso-lateral apophyses of aedeagus nearly straight in lateral view (Fig. 31) (in N. nomurai curved ventrad).

Body length: 10.7���12.5 mm (from front margin of head to apex of abdomen), 5.1���5.4 mm (from front margin of head to apical margin of elytra). Body (Fig. 1) dark brown; mouthparts, tarsi and apical margin of abdominal tergites paler. Head with dense and fine punctation, shorter than wide (length/width = 0.88), eyes flat, temples about twice as long as eyes. Dorsal macrosetae (one side only): one near base of antenna; one medially between eyes; two near neck constriction; two on temple, of which one near posterior margin of eye, one near neck constriction. Antennae slender; relative length of antennal segments (from 1 st to 11 th, each measured from base to apex): 91.0: 58.0: 28.0: 22.0: 25.0: 22.0: 20.0: 18.0: 15.0: 17.0: 24.0; relative width of antennal segments (from 1 st to 11 th, maximal width: 19.0: 11.0: 10.5: 11.0: 14.0: 14.0: 15.0: 17.0: 18.0: 18.0: 18.0. Pronotum shorter than wide (length/width = 0.85), longer (pronotum/head = 1.26) and wider (pronotum/head = 1.32) than head, widest at rounded posterior angles; with punctation finer than those on head. Dorsal macrosetae (one side only): one on disc near its middle; two on disc laterally. Elytra with dense and coarse punctation and brown setae, shorter than wide (length/width = 0.86), slightly longer (pronotum/head = 1.04) and wider (pronotum/head = 1.02) than pronotum. Wings well developed. Scutellum with punctation and setae similar to those on elytra. Abdomen with coarse punctation except for the median part of tergite 2; tergite 7 with whitish apical seam; all tergites with dense transverse microsculpture. Legs densely covered with brown setae, with spines on external sides of all tibiae. Male. Tergite 10 (Fig. 2) gradually narrowed apically, with several long setae situated at apical and lateral margins; sternite 9 (Fig. 3) very long and slender, with numerous long setae at apical portion. Aedeagus (Figs 4, 5): median lobe long and narrow apically; paramere relatively small, with two short branches, with 4���8 sensory peg setae on each apex. Female. Tergite 10 (Fig. 6) with several long setae situated at apical and lateral margins. Distribution. China (Fujian, Zhejiang). Remarks. The new species can be distinguished from Anchocerus shibatai Smetana (1995) and A. schuelkei Smetana (2005) by its relatively larger size; by dense and fine punctuation of head; and by different shape of the aedeagus. It can be distinguished from the unnamed species of Anchocerus mentioned by Smetana (2005) from Fujian Province of China by dense punctation of head and by the female tergite 10 that has setae only near margins in its apical portion. The new species seems to be rather similar with A. nepalicus Smetana (1988), but it differs from the later by its larger size and much shorter branches of the paramere. Etymology. The specific name is derived from the Latin word ��� giganteus ���, after the relatively large size of body of the new species., Published as part of Hu, Jiayao, Li, Lizhen & Zhao, Yunlong, 2010, A new species of the genus Anchocerus Fauvel, 1905 from China (Coleoptera: Staphylinidae: Staphylininae), pp. 65-68 in Zootaxa 2523 on pages 65-67, DOI: 10.5281/zenodo.196370, {"references":["Smetana, A.
