Millerichthys
The Mexican rivulus (''Millerichthys robustus'') is a species of killifish from the family Rivulidae which is endemic to Mexico where it is found in the Papaloapan and Coatzacoalcos River basins. This annual killifish grows to a total length of . It is the only known species in its genus, but its exact taxonomic position remains uncertain, as it has not been included in any phylogenetic In biology, phylogenetics (; from Greek φυλή/ φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups o ... study. This species was described by Robert Rush Miller and Carl Leavitt Hubbs as ''Rivulus robustus'' in 1974, it was reclassified in the monotypic genus ''Millerichthys'' in 1995, the generic name honouring Robert Rush Miller.

Rivulidae
The Rivulidae are a family of killifishes in the order Cyprinodontiformes. They are commonly known as rivulids, South American killifish or New World killifish. The latter names are slightly misleading, however, as they are neither restricted to South America – though most are in fact found there –, nor are they the only killifishes from the Americas. Occasionally, they are still referred to as rivulines, a term dating back to when they were considered a subfamily of the Aplocheilidae. The subfamilial name "Rivulinae" was already established for noctuid moths by Augustus Radcliffe Grote in 1895. That name, though it is the senior homonym, may be suppressed because the name Rivulinae for the fish subfamily is widespread, whereas the moth taxon is little used. The use of Rivulidae as the name for this family may need to be ruled in by the International Commission on Zoological Nomenclature. The alternative family-group name Cynolebiidae Hoedeman 1961 has been prop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
