What Kind Of Cory Is This?

[mancin]

I bought 4 cories (which is all they had in this group) advertised as melini cories I know the first one is, but I'm not sure what the other 3 are. I thought the stripe just wasn't visible due to stress from the transport, but now that they have settled in and colored up (turns out they actually have dots) I don't think they are the same. Ideally I'd like to have 6 - 8 total and plan on adding to the group once I can find more.
 
Here's the melini (on the bottom):
 

 
Here are the unknowns:

They look like Delphax, can you get a better pic?

Yes I will try. That would not be great news as I was looking for cories that can sustain higher temps as they will be kept with Angelfish.

Sterbai thrive in higher temps & are commonly available

Broke out the nice camera:

That's originally what I went to the store for and two different LFS didn't have them. They said the melini would do well as they were being kept with discus and from what I could quickly look up on my phone that seemed to work so I bought them. But if these are indeed delphax (which they seem to be now that I googled the pic and compared it to the one above), that's not going to work.

If I recall correctly, the only other type of cory they had was a julii cory. Should I swap these for those? I just don't want to keep them in the wrong conditions, you know?

I'm no expert but they do seem to be delphax.
I'd double check the Julii in the Lfs actually are Julii as they're rarely seen, they're more likely to be trilineatus

True julii rarely show up in shops.  Trilineatus are more likely the ones the store has.
 
 
I'd second the 'delphax' ID.

Great. Thanks for the help!

Looks to me like it has a lot of the traits of Corydoras Agassizii with it's trade mark gold flash around the gill covers, the delphax that I've seen always had a very dark partial brown/black and quite long dorsal fin and similarly coloured head and eye band.

I can see why you'd say agassazi, but I still think delphax.

I've linked the profiles of both from planetcatfish... and let the OP decide.

I go with @Eaglesaquarium : Delphax to me.
