According to Aqualog, it could be either Corydoras simulatus VARIANTE (Aqualog No. S19983-4) or Corydoras sp. C16 (Aqualog NO. S20416-4). All listed in page 78.
The band in C. simutatus is confimed to the ridge of the back, and does not cross the sides. The true C simulatus is not often seen in the hobby and there will be more information about this to follow at a later date.
C16 is a species that can only be described as a long nosed C. melini, in fact there are several that could fall into this catagory.
