The diversity of two subfamilies of cuckoo wasps in northeastern Brazil is reviewed. Four new species are described and illustrated: Amisega boyi Lucena, sp. nov., A. sertaneja Lucena, sp. nov., and Duckeia dudui Lucena, sp. nov. (Amiseginae), and Cleptidea nordestina Lucena, sp. nov. (Cleptinae). These new species of Amisega and Duckeia represent the first records of both genera in the core zone of the Caatinga dry region, and they seem to be endemic to this portion of the region. The other two Amisega species previously recorded in northeastern Brazil are restricted to ecotone habitats between Caatinga and Atlantic forest. Cleptidea nordestina Lucena, sp. nov. (Cleptinae) is the most septentrional record for the fasciata species group in South America. With the present contribution, the total recorded diversity of Amiseginae and Cleptinae in northeastern Brazil is represented by the following species: A. boyi Lucena, sp. nov., A. flavipes Kimsey, 1987, A. sertaneja Lucena, sp. nov., A. similis Kimsey, 1987, and D. dudui Lucena, sp. nov. (Amiseginae), and C. nordestina Lucena, sp. nov. (Cleptinae).

来自巴西东北部的Amiseginae和Cleptinae，描述了四个新物种（膜翅目、,科）

审查了巴西东北部两个杜鹃黄蜂亚科的多样性。描述并举例说明了四个新物种：Amisega boyi Lucena，sp。十一月，A。sertaneja Lucena，sp。十一月，和Duckeia dudui Lucena，sp。十一月 （Amiseginae）和Cleptidea nordestina Lucena，sp.。十一月 （Cleptinae）。这些新的Amisega和Duckeia物种代表了Caatinga干旱地区核心地区的两个属的第一个记录，它们似乎是该地区的特有物种。先前在巴西东北部记录的其他两个Amisega物种仅限于Caatinga和大西洋森林之间的过渡带栖息地。荷叶克雷德纳（Cleptidea nordestina Lucena），sp。十一月 （Cleptinae）是南美南美板球菌属物种组中最分离的记录。根据目前的贡献，巴西东北部的Amiseginae和Cleptinae的总记录多样性由以下物种代表：A. boyi Lucena，sp。11月，A。flavipes Kimsey，1987年，A。sertaneja Lucena，sp。11月，A。similis Kimsey，1987年； D。dudui Lucena，sp。十一月 （Amiseginae）和C. nordestina Lucena，sp。十一月 （Cleptinae）。
