世界斑叶蝉族昆虫种属组成及地理分布格局

Species composition and geographical distribution pattern of Erythroneurini worldwide

【目的】为了解世界斑叶蝉族昆虫的组成与分布特征,探讨其世界分布格局及可能的起源与演化路径。【方法】基于Dmitriev的3I Interactive Keys and Taxonomic Databases叶蝉分类数据库、中国知网、Web of Science等数据库收集分析斑叶蝉分类研究的相关文献,依据斑叶蝉族地理分布数据,研究1851—2021年7月斑叶蝉族昆虫种属组成及世界地理分布。【结果】全世界共记录斑叶蝉204属1929种。斑叶蝉在各个动物地理区中均有分布,以东洋界为主,共有133属857种,其中特有属98个,特有种765个,分别占斑叶蝉族总数的48.04%和39.66%;热带界次之,共计51属293种,特有属34个,特有种257个,分别占斑叶蝉族总数的16.67%和13.32%;古北界共有45属324种,特有属12个,特有种230个,各占斑叶蝉族总数的5.88%和11.92%;跨区分布的属、种中以东洋—古北界为主,共17属68种,各占总数的8.33%和3.53%;其余除新北界外所占比例均较低。世界斑叶蝉族昆虫地理分布聚类分析表明,世界动物地理区划的相关性为东洋界与古北界、东洋界与热带界、新北界与新热带界彼此间的联系性较强、区内物种间的交流频繁。【结论】全世界共记录斑叶蝉204属1929种,斑叶蝉在各个动物地理区中均有分布,以东洋界为主,东洋界和古北界物种相似性最高,区间联系最为密切。

【Objective】The present paper aimed to know the composition and distribution characteristics of Erythroneurini leafhoppers in the world, and to explore their world distribution pattern and possible origin and evolution path. 【Method】Based on Dmitriev’s 3 I interactive Keys and Taxonomic Databases, China Knowledge Network, Web of Science and other databases, the relevant literature on the classification of leafhoppers is collected and analyzed, and the species composition and world geographical distribution of Erythroneurini from 1851 to July 2021 was studied according to the geographical distribution data of leafhoppers.【Result】A total of 204 genera and 1929 species of Erythroneurini have been recorded worldwide. The Erythroneurini leafhoppers were distributed in all zoogeographic regions, mainly in the Oriental region, with a total of 133 genera and 857 species, including 98 endemic genera and 765 endemic species, accounting for 48.04% and 39.66% of the total number of the Erythroneurini, respectively. The Afrotropical region took second place, with a total of 51 genera and 293 species, 34 endemic genera and 257 endemic species, accounting for 16.67% and 13.32% of the total number of the Erythroneurini, respectively. The Palaearctic region had 45 genera and 324 species, 12 endemic genera and 230 endemic species, accounting for 5.88% and 11.92% of the total number of Erythroneurini tribe, respectively. The cross-regional distribution of genera and species was dominated by the Oriental-Palaearctic world, with 17 genera and 68 species, accounting for 8.33% and 3.53% of the total number of genera and species, respectively, while the rest regions, except for the Nearctic region, have a lower proportion. The clustering analysis of the geographical distribution of Erythroneurini leafhoppers in the world showed the correlation of the world’s animal geographical divisions, which indicated that the relationship between the Oriental and the Palaearctic, the Oriental and the Afrotropical, the Nearctic and the Neotropical are strong, and the species in these regions communicate frequently. 【Conclusion】A total of 204 genera and 1929 species of Erythroneurini are recorded in the world, which are distributed in various zoogeographical regions, mainly in the Oriental world. The species similarity between the Oriental regions and the Palaearctic regions is the highest, and the interval connection is the closest.
