We present surveys of derbid planthoppers associated with coconut (Cocos nucifera L.) and oil palm (Elaeis guineensis Jacq.) collected in Northeastern (Sergipe) and North (Pará and Roraima) Brazil. The surveys were intended to contribute to our knowledge of possible vectors of phytoplasmas or other phloem-restricted plant pathogens. Eight derbid taxa were found, two in the subfamily Cedusinae, tribe Cedusini (Cedusa yipara Kramer and C. yowza Kramer) and six in the subfamily Derbinae, tribe Cenchreini: Herpis sp., Persis pugnax Stål, Omolicna anastomosa (Caldwell), O. nigripennis (Caldwell), and two new species in the genus Agoo Bahder & Bartlett are described here. Genus-level features between Omolicna and Agoo are discussed and a key to the species of Agoo is provided.

我们目前调查收集在巴西东北部（Sergipe）和北部（Pará和Roraima）的椰子（Cocos nucifera L.）和油棕（Elaeis guineensis Jacq。）相关的病虫。这些调查旨在帮助我们了解植物原虫或其他韧皮部限制植物病原体的可能载体。八个derbid类群中发现，两个亚科Cedusinae，部落Cedusini（Cedusa yipara克莱默和C. yowza克莱默）和6个亚科Derbinae，部落Cenchreini：Herpis。SP，Persis pugnax蝽，Omolicna anastomosa（考德威尔），O. nigripennis（Caldwell）和该属中的两个新物种这里介绍了Agoo Bahder＆Bartlett。之间属级功能Omolicna和Agoo进行了讨论和到的物质的键Agoo设置。
