摘要

Few spider species show truly cosmopolitan distributions. Among them is the banded garden spider Argiope trifasciata, which is reported from six continents across major climatic gradients and geographical boundaries. In orb-weaver spiders, such global distributions might be a result of lively dispersal via ballooning. However, wide distributions might also be artefactual, owing to our limited understanding of species taxonomy. To test the hypothesis that A. trifasciata might be a complex of cryptic species with more limited geographical ranges, we investigated the biogeographical structure and evolutionary history of A. trifasciata through a combination of time-calibrated phylogenetic analyses (57 terminals and three genes), ancestral range reconstruction and species delimitation methods. Our results strongly suggest that A. trifasciata as currently defined is not a single species. Its populations fall into five reciprocally monophyletic clades that are genetically distinct and have evolutionary origins in the Plio-Pleistocene. These clades are confined to East Asia, temperate Australia, Hawaii, the New World and the Old World (Africa and most of the Palaearctic). Our results provide the basis for future investigation of morphological and/or ecological disparity between the populations that are likely to represent species, in addition to examinations of the attributes and dispersal modes of these species.

Trifasciata可能是具有更有限的地理范围的隐秘物种的复杂性，我们通过时间校准的系统发育分析（57个末端和三种基因）来调查A. Trifasciata的生物地图结构和进化史。祖传范围重建与物种划定方法。我们的结果强烈表明，A. Trifasciata，如目前所定义的不是单一物种。它的种群分为五个互动的单胞片，遗传上截然不同，在Plio-epleistocene中具有进化的起源。这些林德被局限于东亚，温带澳大利亚，夏威夷，新世界和旧世界（非洲和大多数Palaearctic）。我们的结果为未来调查可能代表物种的种群之间的形态和/或生态差异的基础，以及这些物种的属性和分散模式的检查外。
