Using the mitochondrial barcoding region to correlate research with 58 species in 19 genera of the family Laelapidae with the aim of determining the origin, phylogenetic relationships, and biogeographic historical distribution characteristics of mites in the family Laelapidae. Phylogenetic trees were obtained using Bayesian inference (BI) and Maximum-likelihood (ML) methods, based on three fossil records calibrated as molecular clock nodes, to estimate the divergence time of mites in the family Laelapidae as well as to apply Dispersal-Extinction-Cladogenesis (DEC) analyses to obtain biogeographic history inferences. The result showed species of the genera Hyperlaelaps and Haemolaelaps and some species of the genus Androlaelaps in the family Laelapidae were divided into clades of the genus Laelaps in both the BI and ML trees. Divergence time estimates and biogeographic history analysis revealed that the family Laelapidae likely diverged from other taxa during the Middle Jurassic (ca. 156.73 Mya), with Asia considered the most likely ancestral region for the family Laelapidae. Species of various genera began to undergo massive diversification events during the Cenozoic Tertiary. The results suggest that some genera in the family Laelapidae need to be re-defined or new genera need to be established; the Late Cretaceous to Late Neogene warm period would have promoted the divergence and expansion of species in the family Laelapidae. The divergence and dispersal of the family Laelapidae species is most likely a joint response to the continued northward drift of the Indian plate away from the Gondwana paleo-continent and gradually closer to Asia during the Late Cretaceous and the geological activity of the Tibetan Plateau during the Cenozoic Tertiary. The results strengthen our understanding of the origin and evolution of species in the family Laelapidae.
利用线粒体条形码区域将 19 属 58 种的研究与 Laelapidae 科联系起来，目的是确定螨科螨的起源、系统发育关系和生物地理历史分布特征。基于三个化石记录作为分子钟节点进行校准，使用贝叶斯推断（BI）和最大似然（ML）方法构建系统发育树，估计螨科螨的分歧时间，并应用扩散-灭绝-分支分析（DEC）获得生物地理历史推断。结果表明，螨科中的 Hyperlaelaps 和 Haemolaelaps 属的某些种以及 Androlaelaps 属的一些种在 BI 和 ML 树中均分为 Laelaps 属的分支。分歧时间估计和生物地理历史分析表明，螨科可能起源于中侏罗世（约 156.73 Mya）的其他分类群，亚洲被认为是螨科最可能的祖地区域。各个属的物种在新生代第三纪开始经历大规模的多样化事件。结果表明，螨科中的一些属需要重新定义或建立新的属；白垩纪晚期至新近纪温暖期促进了螨科物种的分化和扩张。螨科物种的分化和扩散很可能是印度板块持续向北远离冈瓦纳古陆并在白垩纪晚期逐渐靠近亚洲以及新生代第三纪青藏高原地质活动的共同反应。结果加强了我们对螨科物种起源和进化的理解。
