''Aspidoras'' is easily distinguished from the other genera of the subfamily Corydoradinae by the presence of a supraoccipital fontanel; this character is an autapomorphy for the genus. Many of the species of ''Aspidoras'' are similar and often hard to distinguish. Without specimens, it is often very difficult to positively identify a species from photographs alone. They are all small species. ''A. taurus'' is exceptional in that it just surpasses 5 cm in length. The monophyly of the genus has been demonstrated.
