Overcoming Linnean and Wallacean shortfall in a biodiversity hotspot-a taxonomic study of Tribasodites Jeannel and allied genera (Coleoptera: Staphylinidae: Pselaphinae) from Nanling Mountain Area, China.

This paper presents the result of a taxonomic study of the genus Tribasodites Jeannel and related genera (Staphylinidae: Pselaphinae: Batrisitae) from Nanling Mountain Area, with 55 species placed in 10 genera being recognized. Forty-one species are described as new, with illustrations of the habitus and diagnostic characters for reliable identifications: Anama angulata sp. nov.

Chenzhilinus, a new subgenus of Euconnus Thomson (Coleoptera: Staphylinidae: Scydmaeninae) from southern China.

A new subgenus of Euconnus Thomson, Chenzhilinus subgen. nov., is erected for E.

The second species of Triartiger Kubota (Coleoptera: Staphylinidae: Pselaphinae) from China's mainland.

Triartiger jiangxinongda Yin & Du, sp. nov. (Clavigeritae: Clavigerini) is described from Meiling National Forest Park, Jiangxi, East China based on two male adults collected by a flight intercept trap, which represents the second known species of the genus from China's mainland.

Notes on the Westwood complex (Coleoptera, Staphylinidae, Pselaphinae) of Hubei, China, with description of a new species and additional faunistic data.

The Westwood complex of genera is represented in Hubei Province by four genera and eight species. Recent field work at Wanchaoshan Nature Reserve, Xingshan County revealed a small series of material belonging to this complex. In this paper, we describe and provide new faunistic data for Yin, Li & Zhao.

Two new species of ant-loving beetles (Coleoptera: Staphylinidae: Pselaphinae) from Jiulong National Wetland Park, China.

Continued collecting efforts at the Jiulong National Wetland Park, Zhejiang, East China revealed two additional species of the ant-loving beetle subfamily Pselaphinae (Coleoptera: Staphylinidae): Trisiniotus jiulong sp. nov. and Arthromelodes lianghongbini sp.

A new Cephennodes Reitter (Coleoptera: Staphylinidae: Scydmaeninae) of C. lustricollis group from East China.

The C. lustricollis group of the scydmaenine genus Cephennodes Reitter was previously represented by three species distributed in northern Vietnam and China (Hong Kong and Guizhou). Here we describe a fourth member, Cephennodes gusu sp.

New material of Euroleptochromus tuberculatus Yin & Cai (Coleoptera: Staphylinidae: Scydmaeninae) in Eocene Baltic amber.

The extinct members of the ant-like stone beetle supertribe Mastigitae are among the best studied groups of all fossil Scydmaeninae, and their evolutionary history can be traced from the latest Albian to the earliest Cenomanian through Miocene/Oligocene, with seven extinct genera being described (summarized in Jaoszyski, 2016; Jaoszyski & Perkovsky, 2016; Jaoszyski et al., 2018; Ross, 20192022 (list of Burmese amber taxa)).

Range extension and male description of a rare clavigerite beetle in China (Coleoptera: Staphylinidae: Pselaphinae).

The myrmecophilous clavigerite Anaclasiger zhudaiae Yin & Huang is known from a single female collected in Guangdong, southern China. Here, I report the discovery of this species in Hunan, central China, associated with Nylanderia flaviabdominis (Wang) ants, which extends its range approximately 630 km northward from the type locality. The male is described for the first time, and the habitus and other major diagnostic characters are illustrated.

The genus Raffray (Coleoptera, Staphylinidae, Pselaphinae) from Nanling Priority Area for Biodiversity Conservation, China.

Prior to this study, no species of Raffray had been reported from Nanling, a vast biodiversity conservation area that spans five provinces in southern China. In this paper, three new species of the genus are described: (Guizhou, Guangxi), (Guizhou), and (Guangxi), suggesting that additional study on the diversity of this group in the area is required. These species are characterized, keyed, and compared to similar congeners, supplemented with illustrations of the habitus and other morphological characters.

A new species of Tyrodes Raffray (Coleoptera: Staphylinidae: Pselaphinae) from China.

A new species of the small pselaphine genus Tyrodes Raffray (Pselaphitae: Tyrini), T. tibialis sp. nov.

Redescription and a new record of Centrophthalmus sinensis Raffray, 1904(Coleoptera: Staphylinidae: Pselaphinae).

A new record of Centrophthalmus sinensis Raffray, 1904 from Suzhou, East China is provided, which is also the first Pselaphinae known to occur in this city, and the third pselaphine species from Jiangsu Province. A redescription of the species is given, aided with illustrations of the habitus and other morphological details.

A new species of Jeannel (Coleoptera, Staphylinidae, Pselaphinae) from Jiulong National Wetland Park, China.

is described from a series of overwintering individuals collected in decomposing wood at Jiulong National Wetland Park, East China. The new species is characterized and separated from related congeners by the unique form of the sexually dimorphic maxillary palpi, greatly swollen male metafemora, as well as by the shape of the genitalia of both sexes. A key to, and a distributional map of, species occurring in China and on the Ryukyu Islands, Japan is provided.
