Unlike the adolfoi, this cory has a almost black dosal fin, in addition to the reddish/pinkish patch behind the gills.
This wild caught species were also seen in the last few months in both North and South Asian markets. There are also real adolfoi mixed in the shipment. So they may be sympatric.
I thought it was more like a Corydoras sp. cf burgessi, but the shop I bought it from indicated that it was shipped in labeled as Corydoras sp. cf adolfoi. The discussion we had was that it was probably because black dosal patch (like those on the C burgessi) was not very consistent through out the specimens but the thin black line along the dosal ridge (like the adolfoi) was very prominent. Anyway, that's just speculation during our chit chat and nothing conclusive came out of it.
Let's see what Ian has to say about this fish.
Cheers,
