本研究的重点是属于 Dolichopoda 的一些西地中海洞蟋蟀物种之间的系统发育关系；主要是地中海属，分布于东比利牛斯山脉至高加索地区。在本文中，对来自法国比利牛斯山 (D. linderi)、科西嘉岛 (D. bormansi 和 D. cyrnensis) 以及意大利北部、中部和南部 (D. ligustica、D. schiavazzii、D. aegilion、D. baccettii、D. laetitiae、D. geniculata、D. capreensis 和 D. palpata) 的 Dolichopoda 物种进行了研究。研究过。另外两个物种，一种来自高加索地区的 D. euxina 和一种来自希腊的 D. remlyi，也被纳入分析中，以及同一科内更遥远的物种被用作外类群。为了阐明这组地中海洞蟋蟀的系统发育关系和生物地理学，对线粒体 DNA 的 1500 个碱基对进行了测序，这些碱基对对应于核糖体 RNA (16S rRNA) 的小亚基和细胞色素氧化酶 I (COI) 的亚基 I。分子数据与系统发育地理学模式一致；地理上接近的物种也是最相关的物种。根据mtDNA的差异，目前遗传多样性的分布似乎受到更新世特征的冰期和间冰期循环所导致的气候事件的影响。 (c) 2005 Elsevier Inc. 保留所有权利。
This study focuses on the phylogenetic relationships among a number of West-Mediterranean cave crickets species belonging to Dolichopoda; primarily a Mediterranean genus, distributed from eastern Pyrenees to Caucasus. In this paper, I I Dolichopoda species from the French Pyrenees (D. linderi), the island of Corsica (D. bormansi and D. cyrnensis), and northern, central, and southern Italy (D. ligustica, D. schiavazzii, D. aegilion, D. baccettii, D. laetitiae, D. geniculata, D. capreensis, and D. palpata) were studied. Two more species, one from the Caucasus, D. euxina, and one from Greece, D. remlyi, were also included in the analyses, together with more distant species within the same family to be used as outgroups. Fifteen hundred base pairs of mitochondrial DNA, corresponding to the small subunit of the ribosomal RNA (16S rRNA) and to the subunit I of the cytochrome oxidase I (COI), were sequenced in order to clarify the phylogenetic relationships and biogeography of this group of Mediterranean cave crickets. The molecular data are congruent with a phylogeographic pattern; with the geographically close species also the most related ones. Based on mtDNA divergence, the present-day distribution of genetic diversity seems to have been impacted by climatic events due to glacial and interglacial cycles that have characterized the Pleistocene era.
