Here we present an overview of the species of the genus Amiserica Nomura, 1974. The taxonomy of the species of eastern Asia (China and adjacent regions) is revised herein, which so far have not been treated yet. Twenty-eight species are discovered new to science: Amiserica basisymmetrica Ahrens, Fabrizi Liu, new species, A. belousovi Ahrens, Fabrizi Liu, new species, A. carolusholzschuhi Ahrens, Fabrizi Liu, new species, A. diaocangshana Ahrens, Fabrizi Liu, new species, A. eucurviforceps Ahrens, Fabrizi Liu, new species, A. fengyangensis Ahrens, Fabrizi Liu, new species, A. funiushanica Ahrens, Fabrizi Liu, new species, A. gibbosiforceps Ahrens, Fabrizi Liu, new species, A. guanmenshanica Ahrens, Fabrizi Liu, new species, A. guizhouensis Ahrens, Fabrizi Liu, new species, A. gulinqin Ahrens, Fabrizi Liu, new species, A. incisa Ahrens, Fabrizi Liu, new species, A. jiuhuensis Ahrens, Fabrizi Liu, new species, A. jizuensis Ahrens, Fabrizi Liu, new species, A. linzhouensis Ahrens, Fabrizi Liu, new species, A. longxinensis Ahrens, Fabrizi Liu, new species, A. lucidiflava Ahrens, Fabrizi Liu, new species, A. nahang Ahrens, Fabrizi Liu, new species, A. panghongae Ahrens, Fabrizi Liu, new species, A. pappi Ahrens, Fabrizi Liu, new species, A. piaoac Ahrens, Fabrizi Liu, new species, A. pseudoantennalis Ahrens, Fabrizi Liu, new species, A. pseudoincisa Ahrens, Fabrizi Liu, new species, A. sacculiforceps Ahrens, Fabrizi Liu, new species, A. strnadi Ahrens, Fabrizi Liu, new species, A. ventriscalptus Ahrens, Fabrizi Liu, new species, A. venxianensis Ahrens, Fabrizi Liu, new species, A. zhongtiaoshanensis Ahrens, Fabrizi Liu, new species. Furthermore, our investigation resulted in two new combinations: Maladera (Eumaladera) loi (Kobayashi, 1991), new combination and Amiserica antennalis (Nomura, 1974), new combination; the first species is thus excluded from Amiserica. A key to species groups and species within groups is given, habitus and male genitalia are illustrated. The distribution of the species revised herein is shown on maps.

The following names were proposed as new without reference to family-group names based on the same type genus which had been made available at an earlier date: Dineutini Ochs, 1926 (Gyrinidae); Odonteini Shokhin, 2007 (Geotrupidae); Fornaxini Cobos, 1965 (Eucnemidae); Auletobiina Legalov, 2001 (Attelabidae). The priority of several family-group names, listed as valid in Bouchard et al. (2011), is affected by recent bibliographic discoveries or new nomenclatural interpretations. †Necronectinae Ponomarenko, 1977 is treated as permanently invalid and replaced with †Timarchopsinae Wang, Ponomarenko & Zhang, 2010 (Coptoclavidae); Agathidiini Westwood, 1838 is replaced by the older name Anisotomini Horaninow, 1834 (Staphylinidae); Cyrtoscydmini Schaufuss, 1889 is replaced by the older name Stenichnini Fauvel, 1885 (Staphylinidae); Eremazinae Iablokoff-Khnzorian, 1977 is treated as unavailable and replaced with Eremazinae Stebnicka, 1977 (Scarabaeidae); Coryphocerina Burmeister, 1842 is replaced by the older name Rhomborhinina Westwood, 1842 (Scarabaeidae); Eudysantina Bouchard, Lawrence, Davies & Newton, 2005 is replaced by the older name Dysantina Gebien, 1922 which is not permanently invalid (Tenebrionidae). The names Macraulacinae/-ini Fleutiaux, 1923 (Eucnemidae), Anamorphinae Strohecker, 1953 (Endomychidae), Pachycnemina Laporte, 1840 (Scarabaeidae), Thaumastodinae Champion, 1924 (Limnichidae), Eudicronychinae Girard, 1971 (Elateridae), Trogoxylini Lesne, 1921 (Bostrichidae), Laemophloeidae Ganglbauer, 1899 (Laemophloeidae); Ancitini Aurivillius, 1917 (Cerambycidae) and Tropiphorini Marseul, 1863 (Curculionidae) are threatened by the discovery of older names; Reversal of Precedence (ICZN 1999: Art. 23.9) or an application to the International Commission on Zoological Nomenclature will be necessary to retain usage of the younger synonyms. Reversal of Precedence is used herein to qualify the following family-group names as : Murmidiinae Jacquelin du Val, 1858 (Cerylonidae) and Chalepini Weise, 1910 (Chrysomelidae). The following 17 Coleoptera family-group names (some of which are used as valid) are homonyms of other family-group names in zoology, these cases must be referred to the Commission for a ruling to remove the homonymy: Catiniidae Ponomarenko, 1968 (Catiniidae); Homopterinae Wasmann, 1920, Glyptini Horn, 1881 (Carabidae); Tychini Raffray, 1904, Ocypodina Hatch, 1957 (Staphylinidae); Gonatinae Kuwert, 1891 (Passalidae); Aplonychidae Burmeister, 1855 (Scarabaeidae); Microchaetini Paulus, 1973 (Byrrhidae); Epiphanini Muona, 1993 (Eucnemidae); Limoniina Jakobson, 1913 (Elateridae); Ichthyurini Champion, 1915 (Cantharidae); Decamerinae Crowson, 1964 (Trogossitidae); Trichodidae Streubel, 1839 (Cleridae); Monocorynini Miyatake, 1988 (Coccinellidae); Gastrophysina Kippenberg, 2010, Chorinini Weise, 1923 (Chrysomelidae); Meconemini Pierce, 1930 (Anthribidae). The following new substitute names are proposed: (to replace Ponomarenko, 1968) and Phoroschizidae (to replace Schizophoridae Ponomarenko, 1968); (to replace Faust, 1894) and Mesostyloidini (to replace Mesostylini Reitter, 1913). The following new genus-group name synonyms are proposed [valid names in square brackets]: Gistel, 1856 [ Fabricius, 1801] (Lucanidae); Gistel, 1856 [ Fabricius, 1775] (Scarabaeidae); Gistel, 1856 [ Latreille, 1797] (Byturidae). Two type genera previously treated as preoccupied and invalid, Latreille, 1828 and Pascoe, 1869 (Tenebrionidae), are determined to be senior homonyms based on bibliographical research. While is treated as valid here, Reversal of Precedence (ICZN 1999: Art. 23.9) is used to conserve usage of Guérin-Méneville, 1831 over.

鞘翅目昆虫是陆地上最大的生物类群, 具有极为丰富的物种多样性和形态多样性, 在陆地生态系统中发挥着重要作用, 与人类社会生产密不可分。定期对世界鞘翅目新分类单元进行汇总整理, 有助于更好地了解鞘翅目多样性的发展动态, 从而促进对生态系统结构与功能的了解以及鞘翅目昆虫资源的开发与保护。本文对2020年发表的世界鞘翅目分类学文献进行了系统地整理与分析。结果表明, 2020年共发表世界鞘翅目新分类单元3,228个(含化石种类), 包括1个新科5个新亚科13个新族218个新属18个新亚属2,973个新种; 提出了1,319个新组合610个新异名49个降级的分类单元及61个升级的分类单元。重点研究的类群包括隐翅虫科(Staphylinidae)、步甲科(Carabidae)、象甲科(Curculionidae)、天牛科(Cerambycidae)等。世界鞘翅目昆虫新物种模式标本产地涉及118个国家和地区, 大部分新物种分布于中国、巴西、墨西哥、厄瓜多尔、印度尼西亚、澳大利亚和越南。收录世界鞘翅目昆虫新发表种的论文/专著共995篇/部, 涉及期刊或出版社141个。2020年, 世界鞘翅目分类学取得了显著进展, 但同时也暴露了新种发现速度略慢于1978-2000年的平均速度以及地区和类群研究力度不均衡的问题, 未来仍需加大投入, 探寻更加高效准确的方法, 以期实现对全球生物多样性的全面评估和保护。

Species distribution, catalogues, phylogeny, and life history traits are the data basis of biodiversity studies, playing critical roles in understanding species origins, evolution, and conservation biodiversity. Recently, a large number of scientific data-sharing platforms have been created, greatly contributing to the development of biodiversity informatics. However, it is difficult for most researchers to deal with big data with high complexity and heterogeneity. Determining how to select and utilize these data accurately and effectively becomes a huge challenge for ecologists and conservation biologists. To better deal with existing problems related to scattered distributed data, we classify biodiversity data resources into four groups (species distribution, catalogues, phylogeny and life history traits), and select representative databases (e.g. Global Biodiversity Information Facility, The Plant List, Open Tree of Life, and The Plant Trait Database (TRY) for demonstration. For each database, data type, and sampling design, geographic coverage and data availability are reported, and selected publications using these datasets are briefly introduced. Meanwhile, we describe recent achievements on the construction of China’s biodiversity digital platforms in each section. Overall, we hope that this paper provides a starting point for researchers to be familiar with these databases and use them correctly, and could have the potential to stimulate the development of related fields in research and conservation of biodiversity under the efforts of researchers and the public.
