Abstract

Erythroneurini is the largest tribe of the microleafhopper subfamily Typhlocybinae. Most prior research on this tribe has focused on traditional classification, phylogeny, and control of agricultural pests, and the phylogeography of the group remains poorly understood. In this study, the mitochondrial genomes of 10 erythroneurine species were sequenced, and sequences of four genes were obtained for 12 geographical populations of . The new sequence data were combined with previously available mitochondrial DNA sequence data and analyzed using Bayesian and Maximum-Likelihood-based phylogenetic methods to elucidate relationships among genera and species and estimate divergence times. was shown to be derived from within . Phylogeographic and population genetic analysis of the endemic Chinese species suggest that the species diverged about 54.85 Mya (95% HPD: 20.76-66.23 million years) in the Paleogene period and that population divergence occurred within the last 14 million years. Ancestral area reconstruction indicates that may have originated in the central region of Guizhou, and geographical barriers are the main factors affecting gene flow among populations. Ecological niche modeling using the MaxEnt model suggests that the distribution of the species was more restricted in the past but is likely to expand in the future years 2050 and 2070.

摘要

红脉叶蝉族是小叶蝉亚科中最大的族。此前对该族的大多数研究都集中在传统分类、系统发育以及农业害虫防治方面,而该类群的系统地理学仍知之甚少。在本研究中,对10种红脉叶蝉族物种的线粒体基因组进行了测序,并获得了12个地理种群的4个基因的序列。新的序列数据与先前可用的线粒体DNA序列数据相结合,并使用基于贝叶斯和最大似然法的系统发育方法进行分析,以阐明属间和种间的关系并估计分歧时间。结果表明,[此处可能有缺失信息未准确翻译]源自[此处可能有缺失信息未准确翻译]内部。对中国特有物种[此处可能有缺失信息未准确翻译]的系统地理学和种群遗传学分析表明,该物种在古近纪时期约5485万年前(95%最高后验密度区间:2076 - 6623万年)发生分歧,且种群分化发生在过去1400万年之内。祖先区域重建表明,[此处可能有缺失信息未准确翻译]可能起源于贵州中部地区,地理障碍是影响种群间基因流动的主要因素。使用最大熵模型(MaxEnt)进行的生态位建模表明,该物种的分布在过去更为受限,但在2050年和2070年未来几年可能会扩大。
