这是第一项综合研究，利用核 28S rRNA 和线粒体细胞色素 b 基因的组合序列数据，评估西部古北收割者科 Dicranolasmatidae、Trogulidae 和 Nemastomatidae 之间的关系，重点关注 Trogulidae 的系统发育和系统学。贝叶斯分析和最大简约法并不能可靠地将 Dicranolasma 解析为不同的科，而是将其置于与 Trogulidae 的几个谱系相似的系统发育水平上。结果证明，线虫科和螟虫科是单系的，螟虫科内的无蛇头属和螟虫属也是单系的。 Calathocratus属、Platybessobius属和Trogulocratus属分别表现为对系或多系，并且与Calathocratus同义。单型 Kofiniotis 属得到了很好的支持。我们显示分子数据与以形态学为特征的分类群总体一致。分子数据对于在同质分类单元内出于系统目的校准形态特征特别有用。在大多数密切相关的有效物种中，我们显示遗传距离的最低水平不低于 5%。就传统上接受的物种而言，按照这个阈值，估计的物种数量比之前认为的要高 1.5-2.4 倍。就欧洲动物群而言，巨蜥科的隐秘多样性显然非常高，但迄今为止在很大程度上被低估了。
This is the first comprehensive study to evaluate the relationships between the western palearctic harvestman families Dicranolasmatidae, Trogulidae and Nemastomatidae with focus on the phylogeny and systematics of Trogulidae, using combined sequence data of the nuclear 28S rRNA and the mitochondrial cytochrome b gene. Bayesian analysis and Maximum parsimony do not reliably resolve Dicranolasma as distinct family but place it on a similar phylogenetic level as several lineages of Trogulidae. Nemastomatidae and Trogulidae turned out to be monophyletic, as did genera Anelasmocephalus and Trogulus within the Trogulidae. The genera Calathocratus, Platybessobius and Trogulocratus each appeared para or polyphyletic, respectively and are synonymized with Calathocratus. The monotypic genus Kofiniotis is well supported. We show molecular data to be in general concordance with taxa characterized by morphology. Molecular data are especially useful to calibrate morphological characters for systematic purposes within homogeneous taxa. In the majority of closely related valid species we show the lowest level of genetic distance to be not lower than 5%. By this threshold in terms of traditionally accepted species the estimated number of species turns out to be 1.5–2.4 times higher than previously believed. With respect to European fauna cryptic diversity in Trogulidae is obviously extraordinarily high and hitherto largely underestimated.
