Supported bimetallic nanocluster catalysts that are distinctly advantageous in optimizing the geometric/electronic effects and maximizing the metal atom utilization have attracted immense interest in the field of heterogeneous catalysis. However, the conventional impregnation techniques often cause poor dispersion of bimetallic particles even on high‐surface‐area supports owing to the lack of strong metal‐support interactions. Here, we present a general route to prepare Ru−M (M=Ga, In, Ge, Sn, Ni) bimetallic nanoclusters with average particle sizes of 1.02–1.24 nm by use of mesoporous sulfur‐doped carbon as supports. The strong chemical interaction between metal and the sulfur atoms that are doped in the carbon matrix can greatly suppress the aggregation of metal species during the H2‐reduction at 600 °C and thus guarantee the formation of small‐sized alloyed nanoclusters. Among these nanoclusters, the prepared bimetallic Ru−Sn nanocluster catalysts show enhanced catalytic activity for the selective hydrogenation of quinoline and furfural with a high turnover frequency of 2948 h−1 and 184 h−1, respectively.

Three new species of Pselaphodes are described and illustrated from Guangxi, South China: P. dayaoensis Yin & Li sp.n., P. hui Yin & Li sp. n. and P. maoershanus Yin & Li sp. n. New distributional data is given for P. condylus Yin, Li &Zhao, 2011 and P. tianmuensis Yin, Li & Zhao, 2010. An updated key is provided to include these additions. The genus presently contains 27 species in China.

Twelve Chinese species of the genus Pselaphodes Westwood, 1870 are described and illustrated. This includes one previously known species, Pselaphodes walkeri (Sharp, 1892), and, eleven new species: P. aculeus Yin, Li & Zhao sp. nov. from Yunnan, P. cornutus Yin, Li & Zhao sp. nov. from Henan, P. declinatus Yin, Li & Zhao sp. nov. from Zhejiang, P. hlavaci Yin, Li & Zhao sp. nov. from Sichuan, P. latilobus Yin, Li & Zhao sp. nov. from Zhejiang, P. miraculum Yin, Li & Zhao sp. nov. from Guizhou, P. nomurai Yin, Li & Zhao sp. nov. from Henan and Shanxi, P. subtilissimus Yin, Li & Zhao sp. nov. from Yunnan, P. tianmuensis Yin, Li & Zhao sp. nov. from Zhejiang, P. torus Yin, Li & Zhao sp. nov. from Qinghai and P. wuyinus Yin, Li & Zhao sp. nov. from Jiangxi and Fujian. Labomimus yunnanicus Hlaváč, Nomura & Zhou, 2002 is transferred to Pselaphodes. A key to all thirteen Chinese species of Pselaphodes is provided.

Five species of Nazeris Fauvel are reported for Guangxi, China. Four of them are described as new: N. huapingensis Hu & Li, sp. n., N. alatus Hu & Li, sp. n., N. exilis Hu & Li, sp. n., and N. chenyanae Hu & Li, sp. n. Additional records of N. obtortus Assing, 2016, an identification key to the Nazeris species in Guangxi, and a map showing their distribution are provided.
