A Taxonomic Study on the Genus Naddia from China (Coleoptera, Staphylinidae, Staphylininae) with Descriptions of Two New Species †

SIMPLE SUMMARY: Naddia is a genus of rove beetles distributed in Asia particularly in its south-eastern part. The species of the genus usually have a large body size and can be recognized by the emarginated base of the head. Naddia species are found to be mimics of sphecid or vespid wasps in both behavior and appearance, which is reported in this paper for the first time. With two new species described in the present paper, 39 species are known from the world, and 12 species are known from China. ABSTRACT: Two new species of Naddia from China are described: N. chenchangchini sp. nov. (Guangxi) and N. hujiayaoi sp. nov. (Zhejiang, Fujian, Jiangxi, Hunan, Guangxi, Guangdong). Naddia atripes Bernhauer, 1939 is new to Vietnam and the following Chinese provinces: Jiangxi, Guangxi, Jiangsu, Shaanxi, Hunan, Hubei, Sichuan, Guizhou, Fujian and Guangdong.
