The species-rich Ambrysus signoreti Stål species complex is diagnosed and subdivided into three sections based on morphology of the female subgenital plate. The species in the first section, characterized by the posterior margin of the subgenital plate with posterolateral corners extending posteriorly further than the central lobe, are revised. The group includes four species: two previously described from Mexico (Ambrysus cosmius La Rivers, A. schuhi Reynoso & Sites), one from Costa Rica (A. variegatus Usinger), and a new species, A. morelosensis n. sp., from central Mexico. The description of the new species and transfer of A. mormon Montandon to the A. guttatipennis Stål species complex brings the total number of species in the complex to 24 and the total number of described species of Ambrysus to 68. Also, an illustrated key to the species in this first section of the complex is provided. Finally, we present new state records from Mexico for A. cosmius and new province records from Costa Rica for A. variegatus.
物种丰富的西诺雷蒂斯安布瑞苏斯（Ambrysus signoreti Stål）物种复合体基于雌性交配板的形态进行了诊断，并细分为三个部分。对第一部分中的物种进行了修订，其特征是交配板后缘的后外侧角向后延伸的距离超过中央叶。该类群包括四个物种：两个先前在墨西哥描述过的物种（科斯米安布瑞苏斯（Ambrysus cosmius La Rivers）、舒氏安布瑞苏斯（A. schuhi Reynoso & Sites）），一个来自哥斯达黎加的物种（杂色安布瑞苏斯（A. variegatus Usinger）），以及一个来自墨西哥中部的新物种，莫雷洛斯安布瑞苏斯（A. morelosensis n. sp.）。新物种的描述以及将摩门安布瑞苏斯（A. mormon Montandon）转移到斑翅安布瑞苏斯（A. guttatipennis Stål）物种复合体中，使该复合体中的物种总数达到24种，安布瑞苏斯属已描述物种的总数达到68种。此外，还提供了该复合体第一部分中物种的图文检索表。最后，我们展示了墨西哥科斯米安布瑞苏斯的新州记录以及哥斯达黎加杂色安布瑞苏斯的新省记录。
