Family of Rivulidae

The family Rivulidae is divided into three subfamilies, which in turn are subdivided into different tribes. Regarding the number of genera there are different opinions. Here 39 genera are listed, some of which contain subgenera.

However, the correctness of the taxonomy listed below cannot be guaranteed within the framework of the ‘International Rivulid Coservation Program’. After all, taxonomy is not the primary function of the IRCP.

The naming of subfamilies and tribes listed above follows VAN DER LAAN, 2019 and VAN DER LAAN, ESCHMEYER & FRICKE, 2014. Apart from that, the taxonomy listed above follows LOUREIRO et al., 2018, except for the synonymization of Austrofundulus with Rachovia, because this approach does not seem to be generally accepted and splitting Rachovia into two genera seems more reasonable to remove the paraphyly of Rachovia. The position of the genus Millerichthys and the non-annual rivulines follows DOMINGUEZ-CASTANEDO et al., 2024.
