Studies conducted with representatives of some genera of Hypostominae showed, within this group, the
diploid number ranges from 2n = 52 to 2n = 80. However, the supposed wide
karyotypic diversity the family Loricariidae or the subfamily Hypostominae
would present is almost exclusively restricted to the genus Hypostomus, and the species from the other genera had a conserved diploid number.[1]
