Ninety-six species of the rove beetle genus Dianous Leach, 1819 have been recorded in China.

In this paper, we describe a new species, D. poecilus n. sp. from Yunnan, and record D. viriditinctus （Champion, 1920） for the first time from China. To facilitate identification of species, species groups and/or species complexes, we compiled a new version of keys, including all species of Dianous hitherto recorded in the territory of China. Moreover, main patterns of geographical distribution are outlined for the world Dianous fauna of this genus.展开更多

The result showed that the individual number, species diversity index （H＇） and the evenness index （J） decreased with the decrea- sing intensity of human disturbance. The species diversity index and the evenness index in human gathering area were the highest of 4.1301 6 and O. 850 2, respec- tively. Simpson predominant index （A） enhanced with the decreasing intensity of human disturbance, which reached the peak of 0. 199 6 in rare disturbance re- gion. The community similarity index/3 of Staphylinidae at different human disturbance regions ranged from 0 -0.25, indicating that the species compositions were extremely different among this four types of regions. Based on these results, it was found that human activities were closely related to individuals number and species dive^ity of Staphylinidae in Erlang Mountain, and human disturbance may add habitat heterogeneity and facilitate to the species diversity of Staphylinidae communi- ties.展开更多
