Abstract

Background: The sky-island Ligidium species fauna in southwest China is poorly known. Before this study, six of the seven sky-island species of the genus were known to be endemic to southwest China. In morphology, Ligidium species are often difficult to identify, and an appraisal of integrative taxonomy is needed.

Results: We integrated morphology and molecular analyses to delimit Ligidium species. Molecular species delimitation based on distance- and evolutionary models recovered seven-candidate lineages from five gene markers (COI, 12S rRNA, 18S rRNA, 28S rRNA and NAK). We also estimated that the species divergences of sky-island Ligidium in southwest China started in late Eocene (40.97 Mya) to middle Miocene (15.19 Mya). Four new species (L. duospinatum Li, sp. nov., L. acuminatum Li, sp. nov., L. rotundum Li, sp. nov. and L. tridentatum Li, sp. nov.) are described. Morphological confusion among L. denticulatum Shen, 1949, L. inerme Nunomura & Xie, 2000 and L. sichuanense Nunomura, 2002 is clarified by integrative taxonomy.

Conclusion: This work confirms that an integrative approach to Ligidium taxonomy is fundamental for objective classification, and deduced the uplift of Qinghai-Tibetan Plateau in the late Eocene and middle Miocene as one of the principal reasons for the species divergences of sky-island Ligidium in southwest China. We also inferred that sky-island mountains have a huge reserve of higher Ligidium species diversity.

中国西南稀有天岛蝎属植物的综合分类(等足目,蛇尾纲,蝎科)。
背景:我国对西南天岛Ligidium物种区系了解甚少。在此研究之前,已知该属的7种天岛种中有6种是中国西南特有的。在形态学上,Ligidium的种类往往难以识别,需要对其进行综合分类鉴定。结果:结合形态学和分子分析,确定了lididium属。基于距离和进化模型的分子物种划分从5个基因标记(COI、12S rRNA、18S rRNA、28S rRNA和NAK)中恢复了7个候选谱系。中国西南天岛Ligidium的物种分化始于始新世晚期(40.97 Mya)至中新世中期(15.19 Mya)。描述了4个新种(L. duospinatum Li, sp. nov、L. acuminatum Li, sp. nov、L. rotundum Li, sp. nov和L. tridentatum Li, sp. nov)。用综合分类学方法澄清了L. denticulatum Shen(1949)、L. inme numura & Xie(2000)和L. sichuan numura(2002)在形态上的混淆。结论:综合分类方法是客观分类的基础,推断青藏高原晚始新世-中新世中期隆升是西南天岛Ligidium物种分化的主要原因之一。我们还推断,天岛山具有较高的liidium物种多样性的巨大储备。
