Abstract

The family-level placement of the species Pacificana cockayni Hogg, 1904 (Araneae, Miturgidae) has been ambiguous for over a century, with the monotypic genus Pacificana initially placed in Agelenidae, later transferred to Amaurobioidinae (Anyphaenidae), and presently in Miturgidae. A recent work describing the male and molecular data consisting of a single mitochondrial gene, cytochrome c oxidase subunit I, confirmed that the species is part of the marronoid clade; however, these data did not result in a conclusive family-level placement. Here, we use low-coverage whole genome sequencing (lcWGS) combined with data from the Sequence Read Archive to infer a phylogeny from ultraconserved elements (UCEs) and six legacy Sanger loci. Indications of potential family placements from prior work and the topologies from this study support a transfer of Pacificana Hogg, 1904 to Cycloctenidae Simon, 1898 (new family placement).

赏金之谜：1904年（Araneae） Pacificana cockayni Hogg的家庭地位。

Pacificana cockayni Hogg, 1904（蜘蛛目，Miturgidae）的科级归属在一个多世纪以来一直很模糊，单型属最初被置于Agelenidae，后来被转移到Amaurobioidinae (amyphaenidae)，目前在Miturgidae。最近的一项工作描述了由单个线粒体基因（细胞色素c氧化酶亚基I）组成的雄性和分子数据，证实了该物种是马龙鱼枝的一部分；然而，这些数据并没有得出决定性的家庭安置结果。在这里，我们使用低覆盖全基因组测序（lcWGS）结合Sequence Read Archive的数据，从超保守元件（UCEs）和六个遗留Sanger位点推断出系统发育。从先前的工作和本研究的拓扑结构中得出的潜在家族定位的迹象支持将Pacificana Hogg， 1904年转移到Cycloctenidae Simon， 1898年（新的家族定位）。

期刊介绍： Molecular Phylogenetics and Evolution is dedicated to bringing Darwin''s dream within grasp - to "have fairly true genealogical trees of each great kingdom of Nature." The journal provides a forum for molecular studies that advance our understanding of phylogeny and evolution, further the development of phylogenetically more accurate taxonomic classifications, and ultimately bring a unified classification for all the ramifying lines of life. Phylogeographic studies will be considered for publication if they offer EXCEPTIONAL theoretical or empirical advances.
