Remarks: An account of Corydoras garbei appeared in Miranda Ribeiro, (1937: 54) that has been treated by some as an independent proposal of a new name for this species.

However, it appears that the account was a repeat of the earlier description of the species and, on that basis, treated by Reis (2003) as a lapsus and not a new name proposal.
