Among the mimosoid legumes (Fabaceae, Caesalpinioideae, mimosoid clade), many genera have complex nomenclatural histories, including Abarema that stands out due to numerous nomenclatural changes. Abarema is a Neotropical genus that currently comprises c. 50 species, with centres of diversity in the Amazon and Atlantic rain forests. Recent phylogenetic studies of Abarema have demonstrated the non-monophyly of the genus, which was shown to be polyphyletic with species traditionally recognized under the genus placed in three main clades that are intermingled with other genera of the former tribe Ingeae. The type species of Abarema groups with Inga, Macrosamanea, Enterolobiump.p., Zygia and Blanchetiodendron, whereas the other two clades correspond to the former genera Jupunba and Punjuba. The aim of this study is to build a phylogenetic tree of Abarema s.l. supporting the reinstatement of Jupunba and Punjuba, based on morphological and phylogenetic evidence, and to carry out a nomenclatural overhaul of the species and implement necessary typifications. For Punjuba we reinstate three species and add three new combinations. Jupunba comprises 37 species, of which eight are reinstated; in addition, the resurrection of one species with a new synonym is proposed and 29 new combinations are made. In total, 63 taxa are revised, including accepted names, synonyms and excluded names. A taxonomic key is presented for the identification of Punjuba, Jupunba and related genera. We present 40 new combinations, one new taxonomic status and 18 corrections of nomenclature category for lectotypes and two neotypes. One lectotype is designated, one species is reinstated with a new synonym and a second step neotypification is made. We located 97 unreported types during the revision, which are cited here for the first time.

基于系统发育证据的 Jupunba 和 Punjuba（豆科）的恢复和再循环

在含羞草豆科植物（豆科、Caesalpinioideae、含羞草进化枝）中，许多属具有复杂的命名历史，包括由于众多命名变化而脱颖而出的 Abarema。Abarema是一个新热带属，目前包括c。50 种，在亚马逊和大西洋雨林中具有多样性中心。最近对 Abarema 的系统发育研究证明了该属的非单系性，该属被证明是多系的，传统上被认为属于该属的物种被放置在三个主要进化枝中，这些进化枝与前部落 Ingeae 的其他属混合。Abarema 的模式种与 Inga、Macrosamanea、Enterolobiump.p.、Zygia 和 Blanchetiodendron 分组，而其他两个进化枝对应于前属 Jupunba 和 Punjuba。本研究的目的是根据形态学和系统发育证据，建立支持恢复 Jupunba 和 Punjuba 的 Abarema sl 的系统发育树，并对物种进行命名改革并实施必要的分类。对于旁朱巴，我们恢复了三个物种并添加了三个新组合。Jupunba包括37种，其中8种已恢复；此外，提出了用新同义词复活一个物种，并制作了29个新组合。总共修订了 63 个分类单元，包括接受的名称、同义词和排除的名称。提供了分类学关键字，用于鉴定 Punjuba、Jupunba 和相关属。我们提出了 40 种新组合、一种新分类状态和 18 种对选型和两种新类型的命名类别的更正。指定一种选型，用新的同义词恢复一个物种，然后进行第二步新类型化。我们在修订期间发现了 97 个未报告的类型，在此首次引用。
