It is likely that it will be revised eventually; if ''Variabilichromis'' is split off, at least some of the more ancient lineages currently placed in ''Neolamprologus'' are probably worthy of separation also. However, the morphological similarity and numerous undescribed species do not make analyses easier, and as with many cichlids, recent

between genera and species is common enough due to extremely low postzygotic isolation. Males of ''Neolamprologus'' apparently have always readily and successfully mated with females of other Lamprologini they found ready to spawn: mtDNA lineages similar to other Lamprologini genera are widely encountered in species placed in ''Neolamprologus''. And not only do such hybrids seem to be fertile at least to a limited extent in many cases, new species often appear to originate from such interbreeding.Day ''et al.''
