The last ice age considerably influenced distribution patterns of extant species of plants and animals, with some of them now inhabiting disjunct areas in the subarctic/arctic and alpine regions. This arctic-alpine distribution is characteristic for many cold-adapted species with a limited dispersal ability and can be found in many invertebrate taxa, including ground beetles. The ground beetle Pterostichus adstrictus Eschscholtz, 1823 of the subgenus Bothriopterus was previously known to have a holarctic-circumpolar distribution, in Europe reaching its southern borders in Wales and southern Scandinavia. Here, we report the first findings of this species from the Austrian Ötztal Alps, representing also the southernmost edge of its currently known distribution, confirmed by the comparison of morphological characters to other Bothriopterus species and DNA barcoding data. Molecular data revealed a separation of the Austrian and Finish specimens with limited to no gene flow at all. Furthermore, we present the first data on habitat preference and seasonality of P. adstrictus in the Austrian Alps.

冰河时期的遗物:地面甲虫Pterostichus adstrictus Eschscholtz,1823年(鞘翅目:Carabidae)在奥地利阿尔卑斯山

上一个冰期极大地影响了现存动植物的分布方式,其中一些现在居住在北极/北极和高山地区的分离区域。这种北极-高山的分布是许多适应能力很差的冷适应物种的特征,并且可以在许多无脊椎动物类群中找到,包括地上的甲虫。地面甲虫Pterostichus adstrictus Eschscholtz,Bothriopterus1823以前已知在欧洲到达其威尔士和斯堪的纳维亚半岛南部边界时具有卵圆形-极地分布。在这里,我们报告了该物种从奥地利Ötztal阿尔卑斯山获得的第一个发现,也代表了其目前已知分布的最南端,这已通过与其他直翅目物种的形态特征和DNA条形码数据进行比较得到了证实。分子数据显示奥地利和完成标本的分离,完全没有基因流。此外,我们提出了有关奥地利阿尔卑斯山体育疫霉栖息地和季节性的一批数据。
