The gonyleptids are one of the most diverse groups of harvestmen, exhibiting a vast range of sizes, shapes and behaviors. However, its internal classification, earlier based on meristic characters, particularly in larger groups such as Pachylinae and Discocyrtus, has been called into question by new proposals that consider morphological and molecular synapomorphies. Here, we aspire to evaluate the transfer of seven species currently classified under Discocyrtus sensu lato and the monotypic genus Oliverius from Pachylinae to Neopachylinae. Additionally, we propose the inclusion of two new species in Neopachylinae. To test our hypothesis, we expand upon previous cladistic analyses using maximum parsimony and incorporate 40 terminals representing Gonyleptoidea, including all existing members of Neopachylinae, and 116 morphological characters. Our results confirm the hypothesis of monophyly of Neopachylinae after the inclusion of the new and transferred taxa. To provide a comprehensive assessment of the results, we update some diagnoses at the genus and species-level within Neopachylinae. Furthermore, to accommodate the taxonomic changes resulting from this study, we propose 1) the establishment of two new genera, 2) the reassignment of five taxa at the generic level, and 3) the establishment of two new junior subjective synonymies at the species level.

进一步排水 Discocyrtus 以扩大 Neopachylinae（Opiliones、Gonyleptidae）：吸收类群并建立新属和新种

角肽是最多样化的收割者群体之一，表现出各种各样的大小、形状和行为。然而，其内部分类，早期基于分生特征，特别是在较大的类群中，如厚毛亚科和盘球亚科，已受到考虑形态和分子共性的新提议的质疑。在这里，我们希望评估目前分类为 ​​Discocyrtus sensu lato 和单型属 Oliverius 下的七个物种从 Pachylinae 到 Neopachylinae 的转移。此外，我们建议在 Neopachylinae 中纳入两个新物种。为了检验我们的假设，我们使用最大简约性扩展了之前的分支分析，并纳入了代表膝足总科的 40 个末端，包括新厚甲亚科的所有现有成员，以及 116 个形态特征。我们的结果证实了在纳入新的和转移的类群后新毛蝽亚科单系的假设。为了对结果进行全面评估，我们更新了新厚甲亚科属和种级别的一些诊断。此外，为了适应本研究引起的分类学变化，我们建议1）建立两个新属，2）在属级重新分配五个分类单元，以及3）在物种级建立两个新的初级主观同义词。
