description: <i>Nazeris songi</i> Ma, Miao &amp; Hu, sp. n. (Figs 2, 9–13, 19) <b>Type material.</b> <b>Holotype: China:</b> male: ‘ China: Guangxi, Jinxiu County, ‘7 km’, 24°09′07″N, 110°12′29″E, mixed leaf litter, sifted, 1300 m, 16.VII.2014, Peng, Song, Yu &amp; Yan leg.’ (SNUC). Paratype: 1 female, same data as holotype. <b>Description.</b> Body length 7.0– 7.1 mm; forebody length 3.8–3.9 mm. Body (Fig. 2) dark brown; antennae and legs yellowish brown. Head (Fig. 9) 1.03–1.06 times as long as wide; punctation very dense, moderately coarse, distinctly umbilicate and partly confluent, interstices lacking microsculpture; postocular portion 1.7 times as long as eye length. Pronotum (Fig. 9) 1.18–1.19 times as long as wide, 0.94–0.99 times as long and 0.84–0.86 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 without microsculpture. Elytra (Fig. 9) 0.59–0.62 times as long as wide, 0.55–0.56 times as long and 1.08–1.12 times as broad 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. <b>Male.</b> Sternite VII (Fig. 10) with posterior margin semi-circularly emarginated at middle. Sternite VIII (Fig. 11) with V-shaped posterior excision. Aedeagus (Figs 12, 13) well sclerotized, ventral process wide and long, gradually narrower to apex in ventral view, with pair of triangular basal laminae ventrally; dorso-lateral apophyses very slender and slightly curved in ventral view, not reaching apex of ventral process. <b>Distribution and habitat data.</b> The species is known only from the Dayao Mountains in middle Guangxi. The specimens were collected by sifting leaf litter at an altitude of 1,300 m. <b>Comparative notes.</b> The new species is very similar to <i>N. megalobus</i> Hu &amp; Li (in Hu <i>et al.</i> 2012: 421, Figs 25–30) in general appearance and aedeagal characters from the same locality, but can be separated by the following characters: punctation of head partly confluent; ventral process of aedeagus wider in ventral view; dorso-lateral apophyses much shorter and slender. <b>Etymology.</b> The species is named in honor of Xiao-Bin Song, who collected one of the type specimens.
