Laimosemion is a subgenus erected by Huber in 1999. Costa (2011) upgraded this subgenus to genus status. This move is not follwed herein.

Included in the subgenus Laimosemion are 23 ?? species: (updated march 2019)

Laimosemion agilae (Hoedeman, 1954),L. breviceps (Eigenmann, 1909), L. cladophorus (Huber, 1991), L. dibaphus (Myers, 1927), L. corpulentus (Thomerson & Taphorn, 1993), L. frenatus (Eigenmann, 1912), L. geayi (Vaillant, 1899), L. gransabanae (Lasso, Taphorn & Thomerson, 1992), L. jauaperi, L. kirovskyi (Costa, 2004), L. lyricauda (Thomerson, Berkenkamp & Taphorn, 1991), L. mahdiaensis (Suijker & Collier, 2006), L. manaen- sis (Hoedeman, 1961), L. nicoi (Thomerson & 240 Copyright © Verlag Dr. Friedrich Pfeil Taphorn, 1992), L. rectocaudatus (Fels & de Rham, 1981), L. romeri (Costa, 2003), L. sape (Lasso-Alcalá, Taphorn, Lasso & León-Mata, 2006), L. strigatus (Regan, 1912), L. tecminae (Thomerson, Nico & Taphorn, 1992), L. torrenticola (Vermeulen & Is- brücker, 2000), L. uakti (Costa, 2004), L. uatuman (Costa, 2004), L. xiphidius (Huber, 1979).

After Costa's work a new paper was released by Huber (2012) in which Huber stated that paper from Costa was not well supported by evidence and in which he reversed the genus names, erected by Costa 2011, back into Rivulus based on 144 external characters that produced evidence that Rivulus was still a monophyletic assemblage.

Huber J.H., 2012. Reappraisal of the Phylogeny of Rivulus and its Allied Focused on External Characters.

In this site we follow the latest evidence produced by Huber (2012) and recon the genus Rivulus as a monophyletic group. It is however possible to search on the new genus names by Costa as well for practical reasons.
