Notophthalmus V. "subspecies"

[Kalessin]

Hi everybody!
I've searched a lot on this forum to check what are the "subspecies" that i own, but im not sure about what they are.
I've got 4 of them, and it seems that I have 2 couples that have same traits.
Checking the caresheet of this forum it seems that they are all N. v. v.
What i fear most, since i plan on breeding them this winter, is that those are already mixed with other subspecies, by who bred and sold them (all as N.v.v.) because of the differences of pattern and spots.

my adult female (she's usually much more brighter, just as much as the male, but i think its because i've moved them to a darker place in their room in the last 2 days):

here is a pic of them mating (the guy who gave me them tried to breed them without success)

as you can see the first little guy and the female are darker on the back and has a well defined black circle around the spots.
I hope that some experts will help me identifying them!
Thank you in advance for the help and sorry for the long post!

In my opinion they're all n.v.v. The spots seem to be way to prominent to be n.v.l., and they're definitely not n.v.p, or n.v.d.

I could see the pics when I clicked on them, but when I right click and open as a new tab or window the pics come up.

Yes, actually my doubt is about a pair being some Louisianensis and not v.v.

Right, usually the spots on Louisianensis are usually very small and sometimes barely noticeable. To me the spots on all of theem are too big and distinguished for them to be Louisianensis.
