Sole species of Quintana (sister genus Girardinus). Before 1934 it was sold as 'Toxus riddlei' and 'Limia heterandria'. CONSERVATION FLAG: IUCN Critically Endangered (possibly extinct); not recorded in the wild since 2007-2008 and no longer in the ornamental trade, so fish offered under this name today are likely mislabelled. Not on Seriously Fish.
