This work aimed to elucidate the distribution of Chrysoperla externa haplotypes and investigate whether it exhibits structure based on genetic composition as opposed to geographic location. The genetic diversity of C. externa, analyzed by AMOVA using the COI and 16S rRNA genes as mitochondrial markers, showed significant haplotype structure arising from genetic differences that was not associated with sampling location. This was reflected in the network grouping. Bayesian inference showed that haplotype distribution may have its origins in C. externa divergence into two distinct clades, which dispersed to various locations, and their subsequent diversification. The evolutionary history of C. externa may include multiple ancestral haplotypes differentiating within the same geographic area to generate the current broad genetic diversity, so that the earlier geographical history has been erased, and now we have highlighted its more recent genetic history.
这项工作旨在阐明外来草蛉单倍型的分布，并研究其是否基于遗传组成而非地理位置呈现出结构。以外来草蛉的COI和16S rRNA基因作为线粒体标记，通过AMOVA分析其遗传多样性，结果表明，由遗传差异产生的显著单倍型结构与采样位置无关。这在网络分组中得到了体现。贝叶斯推断表明，单倍型分布可能起源于外来草蛉分化为两个不同的分支，这些分支扩散到不同的位置，随后发生了多样化。外来草蛉的进化历史可能包括多个祖先单倍型在同一地理区域内分化，从而产生了当前广泛的遗传多样性，以至于早期的地理历史已被抹去，而现在我们突出了其更近的遗传历史。
