Two Neotropical species of the subfamily Castianeirinae are treated herein. Castianeira spinipalpis Mello-Leito, 1945 was described from a single female specimen; we provide a redescription of the female and the male is described for the first time. The species is newly recorded from Paraguay and Bolivia. Also, Myrmecotypus rubioi sp. nov. is described from the Bolivian Moxos plains, a tropical savanna ecoregion of the Beni department of northern Bolivia. The new species can be distinguished from others in the genus by having tibia I spination 3-2, coxa II whitish (the remainder dark), and a unique male palpal embolus with two broad embolic discs basal to the embolus tip.
本文处理了两个新热带的 Castianeirinae 亚科物种。1945 年，Mello-Leito 从一个单一的雌性标本中描述了 Castianeira spinipalpis Mello-Leito；我们提供了雌性的重新描述，并且首次描述了雄性。该物种新记录于巴拉圭和玻利维亚。此外，Myrmecotypus rubioi sp. nov. 是从玻利维亚莫克索斯平原（玻利维亚北部贝尼省的热带稀树草原生态区）描述的。新种与属中的其他种不同，其特征为胫节 I 具刺 3-2，后足 II 白色（其余为深色），以及独特的雄性触肢器触须，在触须尖端下方有两个宽阔的触须盘。
