Using a sample of 257 individuals from 53 recognized species, Durand et al. (2012a,b) highlighted 91 lineages or Operational Taxonomic Units (OTUs) in the Mugilidae phylogenetic tree. Seven of these OTUs were in samples of undescribed species (because the morpho-anatomical description was either not available or did not match any species description).

2012b) to create the genus Neochelon. In the phylogenetic tree that combines mitochondrial and nuclear gene sequences (Fig. 1), Neochelon is the most divergent genus among all genera of the Cheloninae subfamily (Xia et al. submitted). It is supported by two diagnostic morpho-anatomical traits: 11 soft rays in the anal fin, scales with a membranous, digitated hind margin (Xia et al. submitted, Fig. 2). Neochelon falcipinnis the unique species of the genus Neochelon, occurs in West Africa from Saint-Louis in northern Senegal to Congo (Thomson 1997).
