I'd pull them and incubate them so they can hatch in a separate tank. You'll have better survival. guide: http://www.corydorasworld.com/the_fish_house/egg_hatching_fry_raising
In terms of knowing which species? Can't. Not from the eggs, at least. Most cory eggs look the same, with a few exceptions in size.
Thanks for posting this. I let it totally slip my mind that Ian Fuller is the most successful breeder of Corydorus. I believe he has bred over 120 different species of just Cory alone. His website I can only imagine is a invaluable wealth of knowlege. The next time I witness a spawn I may just jump in and subcribe to his site.
In the meantime, I dug up an old interview that Frank Falcone recorded with him back in 2009. He discussed in enough detail about how to handle the eggs and raise the young that I felt confident that I could handle this no problem.

I decided it would be best for the time being to keep them in the the tank they were spawned until they reach such a size that would be safe to retank them. I am preparing a 5 gallon that will be used to grow them out for a few month until they are to large to be considered as food.
Speaking of food, i am mixing it up between hikari first bites, artemia nauplii, crushed shrimp pellets, and frozen emerald entree.
Best I can tell there are at least five young in the net. Hard to tell how many because the net is complicated with hiding places, however I have seen five simultaneously.
So... So far so good, I will keep updating as things progress.
