On the basis of the song and morphological analyses, we revised the status of the subspecies Stenobothrus eurasius eurasius Zubowsky, 1898, and S. eurasius hyalosuperficies Vorontsovskii, 1927. The status of the subspecies S. eurasius hyalosuperficies Vor. has been changed to the species level. The most striking difference between S. eurasius and S. hyalosuperficies lies in the song parameters. The calling songs differ not only in temporal parameters but are also produced by different mechanisms. S. eurasius generates calling songs by common leg stridulation, whereas S. hyalosuperficies produces sound by wing clapping. The courtship songs of both species are complex (contain several elements) and very different in temporal structure. The morphological differences between the two species are not as striking as the differences in bioacoustics: we found the only differences in the hind wing venation. At the same time, we suggest these differences to be important since they might be due to different mechanisms of sound production. We revised the ranges of the two species on the territory of Ukraine, Russia and Kazakhstan. We also reviewed the type localities of S. eurasius Zub. and designated lectotype and paralectotype of this species.
基于鸣声和形态分析，我们修订了 Zubowsky 于 1898 年所描述的欧亚粗腿树蟋指名亚种 Stenobothrus eurasius eurasius 和 Vorontsovskii 于 1927 年所描述的欧亚粗腿树蟋透明翅亚种 Stenobothrus eurasius hyalosuperficies 的分类地位。欧亚粗腿树蟋透明翅亚种的分类地位被提升为种级。欧亚粗腿树蟋和透明翅亚种之间最显著的区别在于鸣声参数。求偶鸣声不仅在时间参数上有所不同，而且产生的机制也不同。欧亚粗腿树蟋通过常见的腿部摩擦产生求偶鸣声，而透明翅亚种则通过翅膀拍打产生声音。这两个物种的求偶鸣声都很复杂（包含几个元素），在时间结构上也非常不同。这两个物种的形态差异并不像生物声学上的差异那么明显：我们只发现了后翅脉序上的差异。同时，我们认为这些差异很重要，因为它们可能是由于产生声音的不同机制造成的。我们修订了这两个物种在乌克兰、俄罗斯和哈萨克斯坦的分布范围。我们还回顾了欧亚粗腿树蟋的模式产地，并指定了该种的模式标本和近模式标本。
