A reclassification of several species traditionally included in Rhantus Dejean, 1833 is given: Nartus Zaitzev, 1907 is re-instated as genus with one species in the Nearctic and one in the Palaearctic region; two new genera are erected: Meri-diorhantus n. gen., with M. antarcticus (Germain, 1854) n. comb., M. calidus (Fabricius, 1792) n. comb., M. limbatus (Aubé, 1838) n. comb., M. orbignyi (Balke, 1992) n. comb., M. validus (Sharp, 1882) n. comb. in the Neotropical region (M. calidus also in the southern USA and along the eastern coast as far north as New York City), and the monotypic Caperhantus n. gen., with C. cicurius (Fabricius, 1787) n. comb. in south Africa. Furthermore, nine Pacific and Australian Rhantus are transferred to the genus Carabdytes Balke, Hendrich & Wewalka, 1992: C. alutaceus (Fauvel, 1883) n. comb., C. guadalcanalensis (Balke, 1998) n. comb., C. monteithi (Balke, Wewalka, Alarie & Ribera, 2007) n. comb., C. novaecaledoniae (J. Balfour-Browne, 1944) n. comb., C. oceanicus (Balke, 1993b) n. comb., C. pacificus (Boisduval, 1835) n. comb., C. plantaris (Sharp, 1882) n. comb., C. poellerbauerae (Balke, Wewalka, Alarie & Ribera, 2007) n. comb. and C. pseudopacificus Balke, 1993b) n. comb. All changes are based on a previous comprehensive molecular phylogenetic analysis of Colymbetinae. Diagnostic characters are given for all genera mentioned above and each of them is illustrated with one or more habitus pictures. An updated key to all genera of Colymbetinae is also given.
对传统上归入1833年德让所定的Rhantus属的几个物种进行了重新分类：1907年的Nartus Zaitzev被重新确立为属，在新北区有一个物种，在古北区有一个物种；建立了两个新属：Meri-diorhantus新属，包含M. antarcticus（热尔曼，1854）新组合、M. calidus（法布尔，1792）新组合、M. limbatus（奥贝，1838）新组合、M. orbignyi（巴尔克，1992）新组合、M. validus（夏普，1882）新组合，分布于新热带区（M. calidus也分布于美国南部和东海岸，北至纽约市），以及单型的Caperhantus新属，包含C. cicurius（法布尔，1787）新组合，分布于南非。此外，9种太平洋和澳大利亚的Rhantus被转移到1992年巴尔克、亨德里希和韦瓦尔卡所定的Carabdytes属：C. alutaceus（福韦尔，1883）新组合、C. guadalcanalensis（巴尔克，1998）新组合、C. monteithi（巴尔克、韦瓦尔卡、阿拉里和里韦拉，2007）新组合、C. novaecaledoniae（J. 巴尔弗-布朗，1944）新组合、C. oceanicus（巴尔克，1993b）新组合、C. pacificus（布瓦杜瓦尔，1835）新组合、C. plantaris（夏普，1882）新组合、C. poellerbauerae（巴尔克、韦瓦尔卡、阿拉里和里韦拉，2007）新组合和C. pseudopacificus（巴尔克，1993b）新组合。所有这些变化都基于之前对Colymbetinae亚科的全面分子系统发育分析。给出了上述所有属的鉴别特征，并为每个属配有一幅或多幅整体图。还给出了Colymbetinae亚科所有属的最新检索表。
