A Taxonomic Study On The Genus Indoquedius Of And The Genus Bolitogyrus Of China (Coleoptera: Staphylinidae: Staphylininae)

Staphylinidae is one of the largest families in Coleoptera in Insecta. About 36000 species of thisfamily have been known to the world. They occupy a wide variety of habitats consisting of fields,forests, jungles, mountains, riversides and shores; some species are even mammal ectozoa. Theyfeed on a wide range of food; besides most carnivorous species, there are also omnivorous,saprophagous, coprophagous, fungivorous, carpophagous and pollinophagous species. Staphylinidaehas a close relationship with human and is a unneglectable natural resource. Some of them could benatural enemies of verminous insects, and some could be used as medicinal materials while some arehygienic pests.The genera Indoquedius and Bolitogyrus are belonging to the tribe Quediini of the subfamilyStaphylininae of family Staphylinidae.The genus Indoquedius was established by Blackwelder (1952). The type species is Quediusoculatus Fauvel, 1895. Indoquedius was once considered as a subgenus Of Quedius by Stephens,1829. Smetana (1988) upgraded Indoquedius as a new genus. Up to the present, 32 species of thegenus have been known from the world and 24 from China (4 from Taiwan only and 1 from bothMainland and Taiwan).The genus Bolitogyrus was established by Chevrolat (1842). The type species is Quediusbupthalrnus Erichson, 1840. Up to the present, 34 species of the genus have been known from theworld and 12 from China (1 from Taiwan only and another One from both Mainland and Taiwan).In world fauna, China bestrides both Palaearctic and Oriental Regions. Because of the manyspecies of this two genus in China, the author selected it as the topic of his MS thesis. The Study wasbased on consulting all related literature and careful examinations of 65 specimens collected frommany places in China such as Jilin, Yunnan, Guizhou, Xizang and Hainan. The results of this studyare summarized as below:1. This paper was the first systematic study of the genera Indoquedius and Bolitogyrus ofChina mainland.2. Within the paper, 18 species of the genus Indoqquedius, which includes 15 new species and2 new recorded species, and 6 species of the genus Bolitogyrus, which includes 4 newspecies, 1 new recorded species of mainland are recognized; and the male of Bolitogyruspictus was first found. In all, 24 species of the two genera of China mainland arerecognized, including 19 new species.3. All involved species were described detailedly, with the research history, synonym,collecting data and distribution of each species. The color photos of all the species weregiven and the diagnostic characters were illustrated.4. The key to species of the 2 genera of China mainland was provided. 5. A catalog of the two genera of worl'l was edited.6. A database of all the known species of two genera the world was established.7. In this paper, the 12 genera of tribe Quediini of China were classified: the key to the generawas given; the figures of every genus were illustrated.Abstracts of the New Species in This Paper1.
