The Ambrysus signoreti Stål species complex was recently diagnosed and subdivided into three sections based on morphology of the female subgenital plate. In the present study, the species in the second section, characterized by the posterior margin of the subgenital plate with central lobe extending posteriorly further than the posterolateral corners, are revised. Supplemental descriptions for four species described by La Rivers and Usinger are provided. The group includes six species: four from Mexico (Ambrysus brailovskyi Reynoso & Sites, A. henryi Reynoso & Sites, A. inflatus La Rivers, A. lundbladi Usinger), one from Mexico and the United States (A. lunatus Usinger), and one from Costa Rica (A. harmodius La Rivers). Also, the subspecies A. lunatus menoides La Rivers is proposed as a junior synonym of A. lundbladi. We herein report for the first time characteristics of the previously unknown male of A. lundbladi. Additionally, we present new state records from Mexico for A. inflatus and A. lundbladi, and new province records from Costa Rica for A. harmodius. Finally, an illustrated key to the species in the second section of the complex is provided.
安布瑞斯索雷蒂塔尔物种复合体最近根据雌性生殖器板的形态被诊断并细分为三个部分。在本研究中，第二部分的物种，其生殖器板后缘的中央裂片向后延伸超过后外侧角，被修订。为 La Rivers 和 Usinger 描述的四个物种提供了补充描述。该组包括六个物种：四个来自墨西哥（安布瑞斯索雷蒂塔尔 Reynoso & Sites、A. henryi Reynoso & Sites、A. inflatus La Rivers、A. lundbladi Usinger），一个来自墨西哥和美国（A. lunatus Usinger），一个来自哥斯达黎加（A. harmodius La Rivers）。此外，提议将亚种 A. lunatus menoides La Rivers 作为 A. lundbladi 的同物异名。我们在此首次报告了以前未知的 A. lundbladi 雄性的特征。此外，我们还报告了墨西哥新的 A. inflatus 和 A. lundbladi 的州记录，以及哥斯达黎加新的 A. harmodius 的省记录。最后，提供了该复合体第二部分物种的带插图的关键特征。
