Termitogastrina is a subtribe of termitophilous rove beetles distributed mostly across Neotropical and Afrotropical regions. In 1923, William M. Mann established the genera Ceratoxenus and Xenopelta from material collected by Alfred E. Emerson in Guyana. Nine years later, Emerson himself synonymized the genera, in what seems to be a result from the misidentification of specimens. In this work, we revalidate the genus Ceratoxenus, provide its redescription and a taxonomical key for the species, along with a comparative diagnosis with the genus Xenopelta. Additionally, two new species of Ceratoxenus are described: C. akerata sp. nov. and C. inflatus sp. nov., respectively, from Panama and Guyana. This paper also marks a new record for the genus Ceratoxenus for Panama.
白蚁隐翅虫亚族是一类喜蚁性隐翅虫，主要分布在新热带区和热带非洲地区。1923年，威廉·M·曼恩根据阿尔弗雷德·E·爱默生在圭亚那采集的标本建立了角蚁甲属和异甲属。九年后，爱默生本人将这两个属同义化，这似乎是标本误认的结果。在这项研究中，我们重新确认了角蚁甲属，对其进行了重新描述并提供了该属物种的分类检索表，同时与异甲属进行了比较诊断。此外，还描述了角蚁甲属的两个新物种：分别来自巴拿马的阿克勒塔角蚁甲新种和来自圭亚那的肿角蚁甲新种。本文还记录了角蚁甲属在巴拿马的新分布记录。
