Tapinoma species, and more general dolichoderine ants, are able to produce a variety of volatile compounds they use as chemical defense, alarm, and communication pheromones. Among these, iridoids and volatile ketones are the predominant molecule classes produced by the anal glands of these ants. A recent taxonomic revision of the genus Tapinoma in Europe revealed that the supercolonial species Tapinoma nigerrimum consists of a complex of four cryptic species. Two of them, Tapinoma magnum and the newly described Tapinoma darioi, are closely related species that evolutionary diverged recently. In this work, we determine and characterize the chemical profile of pheromones and volatile compounds of two Tapinoma species. From a chemical point of view, T. darioi and T. magnum show both qualitative and quantitative differences in the pheromones produced, supporting the taxonomic revision of the T. nigerrimum complex. Our data confirm T. darioi and T. magnum as separate species also from a biochemical point of view demonstrating the value of chemotaxonomy as a suitable tool for integrative studies of species differentiation even for closely related taxa.

墨西哥锥虫的类虹膜和挥发性信息素:与紧密相关物种大锥虫的化学差异

Tapinoma物种以及更常见的dolichoderine蚂蚁能够产生多种挥发性化合物,用作化学防御,警报和通讯信息素。其中,鸢尾酮和挥发性酮是这些蚂蚁的肛门腺产生的主要分子类别。欧洲最近对Tapinoma属的分类学修订显示,超殖民地物种Tapinoma nigerrimum由四个隐性物种组成。它们中的两个,即锥虫Tapinoma magnum)和新近描述的锥虫Tapinoma darioi),是近缘物种,最近进化分化。在这项工作中,我们确定并表征了两种锥虫的信息素和挥发性化合物的化学特征种类。从化学的角度来看,达里奥氏螺旋藻T. magnum在产生的信息素中显示出质和量上的差异,从而支持了T. nigerrimum复合物的分类学修订。我们的数据证实T. darioiT.马格南作为独立的物种也从一个角度生化点展示化学分类的值作为物种的综合研究合适的工具即使是密切相关类群的分化。
