摘要

这项研究首次利用分子标记和染色体以及中间表型证明,Dorcadion标本是意外的第一代杂交种。分析基于两个线粒体和五个核分子标记。在分析该杂交种的假定亲本类群时,发现即使是 Dorcadion lugubre lugubre Kraatz 也很可能是一个杂交类群。无独有偶,研究人员还发现了与 Dorcadion aethiops(Scopoli)亲本类群有关的新线索,Dorcadion aethiops 已被认为是杂交种。这一杂交的新证据补充了近期发表的文章,从而加强了一种假设,即在多卡迪翁属中,这种现象相对频繁,物种的演化通常呈网状:新的类群可能通过内向杂交出现,这在一定程度上解释了该类群物种极其丰富的原因。

Dissecting natural hybridisation in longhorned beetles through an integrative approach: Further proof of reticulate evolution in Dorcadionini (Cerambycidae, Lamiinae)
This work demonstrates for the first time using molecular markers alongside chromosomes and the intermediate phenotype that a specimen of Dorcadion is an accidental first‐generation hybrid. The analyses were based on two mitochondrial and five nuclear molecular markers. While analysing the putative parental taxa of the hybrid, it was revealed that even Dorcadion lugubre lugubre Kraatz is likely a hybridogenic taxon. Coincidentally, a new lead was discovered concerning the parental taxa of Dorcadion aethiops (Scopoli), already known as a hybridogenic species. This new evidence of hybridisation adds to the recent publications to strengthen the hypothesis that, in Dorcadionini, this phenomenon is relatively frequent, and speciation is often reticulate: New taxa can appear through introgressive hybridisation, explaining in part the extreme species richness of the group.
