Arachnids comprise one of the most diverse groups of animals, with numerous representatives in all terrestrial ecosystems. Aside from Acari (mites and ticks), whose total estimated diversity might reach up to one million species, the orders Araneae (spiders) and Opiliones (harvestmen or daddy longlegs) are the most diverse arachnid lineages. The main goal of this project is to carry out taxonomic revisions (monographs) of several lineages across selected Neotropical groups in two arachnid orders (Araneae [spiders] and Opiliones [daddy long legs]). The groups that we have targeted in this proposal are mainly leaf litter inhabitants (except for mimetids), grossly undersampled and understudied, that lack modern revisionary work and include many undescribed taxa at the species level and above, and thus provide excellent research and training opportunities in modern monography and systematics. The largely overlapping Neotropical distribution of our study groups allows us to effectively collect these arachnids in joint field expeditions. Some of these study taxa also pose similar biogeographic and evolutionary questions that can be addressed with common methodology and expertise. To carry out our research and training goals the PIs have assembled a team of scientists with diverse backgrounds in systematics and arachnology and a demonstrated history of successful collaborative research efforts. Combining research efforts to tackle these taxonomic problems provides the empirical basis for our multi-ordinal and multidisciplinary approach for training doctoral students in the broadest possible way. Lab rotations and collaboration among the multiple investigators participating in the projects, in addition to the joint field expeditions, also contribute to this synergism. Research results will be disseminated in high impact portals such as Encyclopedia of Life and Tree of Life. Online interactive identification tools will also be produced.

蛛形纲动物是最多样化的动物群体之一，在所有陆地生态系统中有众多代表。除了总多样性估计可能达到100万种的阿卡里（螨虫和蜱虫）外，蜘蛛目（蜘蛛）和Opiliones目（收割者或长腿爸爸）是最多样化的蛛形纲动物谱系。该项目的主要目标是对两个蜘蛛目（蜘蛛目[蜘蛛]和蜘蛛目[长腿爸爸]）中选定的新热带区群的几个谱系进行分类学修订（专著）。我们在本建议中针对的群体主要是落叶层居民（除了拟态动物），严重采样不足和研究不足，缺乏现代修订工作，包括许多未描述的类群在物种水平和以上，从而提供了极好的研究和培训机会，在现代专题论文和系统学。 我们的研究组的新热带分布在很大程度上重叠，使我们能够有效地收集这些蛛形纲动物在联合实地考察。其中一些研究分类群也提出了类似的地理和进化问题，可以用共同的方法和专业知识来解决。 为了实现我们的研究和培训目标，PI已经组建了一个具有系统学和蜘蛛学不同背景的科学家团队，并展示了成功合作研究的历史。结合研究工作，以解决这些分类学问题，为我们的多序数和多学科的方法，以最广泛的方式培养博士生提供了经验基础。实验室轮换和参与项目的多名研究人员之间的合作，以及联合实地考察，也有助于这种协同作用。 研究结果将在高影响力的门户网站上传播，如生命百科全书和生命之树。 还将制作在线互动身份查验工具。
