近缘的蝗虫物种Stenobothrus rubicundus和Stenobothrus clavatus已知在Mt.希腊北方的托马罗斯。这些物种产生非常不同和复杂的求爱歌曲伴随着视觉显示。我们分析了求爱的歌曲和潜在的摩擦音运动的后腿自然杂交从托马罗斯山。在实验室中，这两个物种也进行了杂交，并将它们的歌声与自然杂交种的歌声进行了比较。一些杂交歌曲被证明具有介于亲本歌曲之间的中间特征，而另一些杂交歌曲则包含完全新的元素。在混合鸣唱中，棒形鸣唱成分占主导地位。这些鸣叫特征可能会影响杂交雄鸟在接触区的交配成功。将杂交歌曲与北欧S. rubicundus种群的歌曲模式进行比较，使我们能够提出S. rubicundus和S. clavatus起源的情景。© 2012 The Linnean Society of伦敦，Biological Journal of the Linnean Society，2012，··，··-··。
The closely related grasshopper species Stenobothrus rubicundus and Stenobothrus clavatus are known to hybridize in a very narrow contact zone on Mt. Tomaros in northern Greece. These species produce very different and complex courtship songs accompanied with visual display. We analyzed the courtship songs and underlying stridulatory movements of the hind legs in natural hybrids from Mount Tomaros. The two species were also hybridized in the laboratory and their songs were compared with the songs of the natural hybrids. Some hybrid songs were shown to have intermediate features between parental songs, whereas other hybrid songs comprised completely new elements. The clavatus-like song elements were found to dominate in hybrid songs. These song features may influence the mating success of hybrid males in the contact zone. A comparison of hybrid songs with the song pattern of the north European S. rubicundus populations allowed us to suggest a scenario of S. rubicundus and S. clavatus origin. © 2012 The Linnean Society of London, Biological Journal of the Linnean Society, 2012, ••, ••–••.
