虽然超级树已经为许多脊椎动物群体（特别是鸟类、哺乳动物和恐龙）建立起来，但无脊椎动物却引起了相对较少的关注。考虑到节肢动物的经济和生态重要性以及对生物多样性的巨大贡献，节肢动物超级树的缺乏尤其令人惊讶。缺乏机器可读源代码树的全面档案，再加上需要软件实现可重复的协议来管理它们，这无疑阻碍了进展。在这里，我们展示了 Achelata（刺龙虾、拖鞋龙虾和珊瑚龙虾）的超级树作为概念证明，它是使用新的超级树特定软件（超级树工具包；STK）并遵循已发布的协议构建的。我们还引入了一种用于归档和管理已发布源代码树的新资源。我们的 Achelata 超级树是由形态和分子源树合成的，代表了迄今为止该组中最完整的物种级树。我们的研究结果与最近的分类学处理一致，证实了仅两个科的有效性：Palinuridae 和 Scyllaridae； Synaxidae 已在 Palinuridae 中解决。单系 Silentes 和 Stridentes 谱系在 Palinuridae 内被发现，并且 Scyllaridae 内的所有亚科都被发现是单系的，除了 Ibacinae 之外。我们证明了构建更大的节肢动物超级树的可行性，最终目标是使用分而治之的策略为整个门构建完整的物种级系统发育。
While supertrees have been built for many vertebrate groups (notably birds, mammals and dinosaurs), invertebrates have attracted relatively little attention. The paucity of supertrees of arthropods is particularly surprising given their economic and ecological importance, as well as their overwhelming contribution to biodiversity. The absence of comprehensive archives of machine-readable source trees, coupled with the need for software implementing repeatable protocols for managing them, has undoubtedly impeded progress. Here we present a supertree of Achelata (spiny, slipper and coral lobsters) as a proof of concept, constructed using new supertree specific software (the Supertree Toolkit; STK) and following a published protocol. We also introduce a new resource for archiving and managing published source trees. Our supertree of Achelata is synthesised from morphological and molecular source trees, and represents the most complete species-level tree of the group to date. Our findings are consistent with recent taxonomic treatments, confirming the validity of just two families: Palinuridae and Scyllaridae; Synaxidae were resolved within Palinuridae. Monophyletic Silentes and Stridentes lineages are recovered within Palinuridae, and all sub-families within Scyllaridae are found to be monophyletic with the exception of Ibacinae. We demonstrate the feasibility of building larger supertrees of arthropods, with the ultimate objective of building a complete species-level phylogeny for the entire phylum using a divide and conquer strategy.
