description: Diartiger songxiaobini (Yin & Li, 2010), new combination
Microdiartiger songxiaobini Yin & Li, 2010: 369.
Type material examined. Holotype, ♂, labeled ‘ China: Zhejiang Prov. West Tianmushan Mt., elev. 1100 m, 1.v.2009, Xiao-Bin Song leg.’ (SNUC). Paratypes, 1 ♂, 1 ♀, same label data as holotype (SNUC).
Additional material examined. 1 ♂, 5 ♀♀, labeled ‘ China: SW Anhui, Liu’an City, Yue’xi County, Yaoluoping N. R., 30°58′24″N, 114°03′47″E, path near Zhaoguan, under rock, colony of Lasius sp., ca. 1235 m, 20.vi.2013, Dai & Peng leg. (SNUC)’; 1 ♂, labeled ‘ China: Jiangxi, Fengxin County, Baizhang Village, path in Mt., nr. Village, 28°41′41″N, 114°46′52″E, ca. 840 m, sifted, 15.vi.2013, Jia-Yao Hu leg.’ (SNUC).
Distribution. East China: Zhejiang, Anhui, Jiangxi. (new for Anhui and Jiangxi)
Comments. The populations from Anhui and Jiangxi can be readily identified as Diartiger songxiaobini because the male features are identical to those of specimens from the type locality. It is worthy of a note that the type material of this species was collected from colonies of Pachycondyla chinensis.
Nomenclatural notes. An incorrect spelling of the specific epithet occurred twice in Yin et al. 2010 (page 637, Abstract, line 3; page 642, figure caption, line 1), as ‘ M. pachycoincolatus ’, which is an incorrect original spelling and an unavailable name in zoological nomenclature.
Key to males of Diartiger from China

- Dorsal surface of head and pronotum covered with dense, fine setae; mesotrochanters with spine of various forms......... 2
2 Fourth antennomeres more than twice length of third antennomeres (Fig. 2 A); mesofemora with sharp basoventral spine (Fig. 2 C), mesotibiae with triangular tubercle near middle (Fig. 2 C); metatibiae largely concave along ventral margin (Fig. 2 D). (East China: Anhui)............................................................ D. dentatus Yin & Li, sp. n.
- Fourth antennomeres less than twice as long as third antennomeres (Fig. 3 A; Nomura 1997: 99, Fig. 4 ‘ km.’); mesofemora lacking spine, mesotibiae lacking tubercle near middle (Fig. 3 C; Nomura 1997: 101, Fig. 6‘ km.’); metatibiae simple, not concave (Fig. 3 D)........................................................................................... 3
3 Mesotrochanters with thick triangular ventral projection (Fig. 3 C); aedeagal median lobe with very short, membranous apical lobe (Figs 3 J–L). (East China: Anhui)........................................ D. yaoluopingensis Yin & Li, sp. n.
