The Neotropical water scavenger beetle genus Globulosis García, 2001 is revised. Originally described from a single male specimen from southeastern Venezuela, the genus has since been found in localities across the Guiana Shield region and beyond, including Colombia, Suriname, Guyana, and Brazil. The genus is redescribed. Morphological characters and genetic data from the mitochondrial gene COI from ten populations across its range provide support for two distinct species, corresponding loosely to geography. The type species, G. hemisphericus García, is redescribed and newly recorded from Guyana, Suriname, and Brazil (Amazonas, Para). One new species is described, Globulosis flavus sp. n. from southwestern Venezuela (Amazonas, Bolivar). The genus is associated with lotic habitats, and typically found along the margins of small to medium sized streams. High-resolution habitus and aedeagal images and distribution maps for all species are provided.
新热带区水葬甲属Globulosis García，2001年得到修订。该属最初依据委内瑞拉东南部的一个雄性标本描述，此后在圭亚那地盾地区及其他地区发现，包括哥伦比亚、苏里南、圭亚那和巴西。对该属进行了重新描述。来自其分布范围内十个种群的线粒体基因COI的形态特征和遗传数据为两个不同物种提供了支持，这两个物种大致与地理分布相对应。模式种G. hemisphericus García得到重新描述，并在圭亚那、苏里南和巴西（亚马孙州、帕拉州）有新记录。描述了一个新物种，即来自委内瑞拉西南部（亚马孙州、玻利瓦尔州）的Globulosis flavus sp. n.。该属与流水生境相关，通常见于中小型溪流边缘。提供了所有物种的高分辨率整体图和阳茎图像以及分布图。
