RESUMO
Four new species of the subgenus Microsaurus Dejean, 1833 of the genus Quedius Stephens, 1829 are described based on specimens collected from China: Q. (Microsaurus) indigestus sp. nov., Q. (Microsaurus) purus sp. nov. and Q. (Microsaurus) rectus sp. nov. from Sichuan, and Q. (Microsaurus) medius sp. nov. from Hubei. The new species all belong to the Quedius mukuensis group, which is now increased to a total of 16 species. Line drawings and color illustrations of the adults, and the genitalia of the new species and some other ones are given. A key to all the species of this group is provided.

The subgenus Velleius Leach, 1819 of the genus Quedius Stephens, 1829 is a small and very distinctive group in the subtribe Quediina (Staphylinidae: Staphylininae) with pectinate antennal segments and larvae living in nests of Vespa species. This paper reviews the taxonomy of all Velleius species and analyzes the phylogeny of this group. Two new species, Quedius (Velleius) sagittalis sp. nov. from Shaanxi, China and Q. (V.) rectilatus sp. nov. from Guangdong, China, are described. Q. (V.) simillimus (Fairmaire,1891) syn. nov. is proposed as a new synonym of Q. (V.) pectinatus (Sharp, 1874). Phylogenetic result shows that all nine Velleius species can be divided into two clades and both have strong tree supports of Bremer/Bootstrap/Jackknife values.

Eight new species of the subgenus Microsaurus Dejean, 1833 of the genus Quedius Stephens, 1829 are described based on specimens collected in China, namely Q. aculeatus sp. nov., Q. acutulus sp. nov., Q. altus sp. nov., Q. capillus sp. nov., Q. perlucidus sp. nov., Q. postangulus sp. nov., Q. subwrasei sp. nov. from Sichuan and Q. arcus sp. nov. from Ningxia. The female of Q. songpanoides Smetana, 2009 is described for the first time. These new species belong to the Quedius euryalus group and the fauna of this species group is thus increased to 53 species. In addition, this paper reviews the taxonomic history of the Quedius euryalus group and reports the sexual dimorphism in the hind wing length, i.e. male with longer hind wings in many species of the Quedius euryalus group. Line drawings and color illustrations of adults and genitalia of the new species and some other ones are provided, along with a key to all the known species of the euryalus group.

Three new species of the subgenus Microsaurus Dejean, 1833 of the genus Quedius Stephens, 1829 are described based on specimens collected from China: Q. (Microsaurus) bilobus sp. nov. and Q. (Microsaurus) varius sp. nov. from Sichuan, and Q. (Microsaurus) cornutus sp. nov. from Yunnan. Line drawings and color illustrations of adults and genitalia of the new species are provided.

Seven new species of the genus Bolitogyrus Chevrolat, 1842 are described based on specimens collected in China, namely B. depressus sp. nov. from Guangdong, B. hainanensis sp. nov. and B. magnimaculosus sp. nov. from Hainan, B. metallicus sp. nov. from Hubei, and B. loculus sp. nov., B. profundus sp. nov. and B. uncus sp. nov. from Yunnan. The number of Bolitogyrus species is thus increased to 59. Line drawings and color illustrations of adults and genitalia of the new species and some others are given. A key to species known from China is provided, with the exception of B. fukienensis Scheerpeltz, 1974, which is only known from females. A geographical distribution map of all Chinese species is also compiled.
