我们评估的系统发育和亲缘关系的家庭Pettalidae（Opiliones，Cyphophthalmi），一个教科书的例子，一个古老的温带冈瓦纳分类，通过DNA序列数据从四个标记的成员。分类群采样进行了优化，以涵盖超过70%的家庭中所描述的物种，117内组标本包括在分析中。这些数据被提交给不同的分析处理，包括静态和动态同源性，未修剪和修剪的对齐，以及各种最优性标准，包括简约和最大似然（传统搜索和贝叶斯）。所有的分析发现强有力的支持单系的家庭Pettalidae和它的所有属，除了Speleosiro，这是嵌套在Purcellia。然而，属间的关系并没有得到很好的解决，除了第一次在南非属Parapurcellia和其余物种之间分裂，以及Chileogovea和另一个南非属Purcellia之间的可能关系。大多数属的多样性是中生代，新西兰的三个属中，有两个显示出随着时间的推移不断多样化的证据，与新西兰在渐新世溺水事件中完全淹没的情景相矛盾。来自西澳大利亚的Karripurcellia属和来自新西兰澳大利亚板块的Neopurcellia属具有典型的孑遗模式，具有古老的起源，丰富的现存多样性和最近的多样化。Milipurcellia卡拉曼，2012与Karripurcellia Giribet，2003同义。nov.; Speleosiro Lawrence，1931与Purcellia汉森& Sorensen，1904 syn.新组合为：Parapurcellia transvaalica（Lawrence，1963）comb. nov.; Purcellia argasiformis（Lawrence，1931）comb. nov.
We evaluate the phylogenetic and biogeographical relationships of the members of the family Pettalidae (Opiliones, Cyphophthalmi), a textbook example of an ancient temperate Gondwanan taxon, by means of DNA sequence data from four markers. Taxon sampling is optimized to cover more than 70% of the described species in the family, with 117 ingroup specimens included in the analyses. The data were submitted to diverse analytical treatments, including static and dynamic homology, untrimmed and trimmed alignments, and a variety of optimality criteria including parsimony and maximum-likelihood (traditional search and Bayesian). All analyses found strong support for the monophyly of the family Pettalidae and of all its genera, with the exception of Speleosiro, which is nested within Purcellia. However, the relationships among genera are poorly resolved, with the exceptions of a first split between the South African genus Parapurcellia and the remaining species, and, less supported, a possible relationship between Chileogovea and the other South African genus Purcellia. The diversification of most genera is Mesozoic, and of the three New Zealand genera, two show evidence of constant diversification through time, contradicting scenarios of total submersion of New Zealand during the Oligocene drowning episode. The genera Karripurcellia from Western Australia and Neopurcellia from the Australian plate of New Zealand show a pattern typical of relicts, with ancient origin, depauperate extant diversity and recent diversification. The following taxonomic actions are taken: Milipurcellia Karaman, 2012 is synonymized with Karripurcellia Giribet, 2003 syn. nov.; Speleosiro Lawrence, 1931 is synonymised with Purcellia Hansen & Sorensen, 1904 syn. nov. The following new combinations are proposed: Parapurcellia transvaalica (Lawrence, 1963) comb. nov.; Purcellia argasiformis (Lawrence, 1931) comb. nov.
