That said, the U-chin is a classical madagascariensis trait that isn't found in baroni. I'd say the fact that the offspring have it, is pretty indicative that they have at least some madagascariensis lineage.

There definitely are documented naturally occurring hybrid individuals.

There isn't a published genome for madagascariensis and baroni, right? If you have access to a PCR machine, this would actually be a pretty easy/cheap thing to validate in the lab lol.
I think you're gravely underestimating the ease and costs of DNA sequencing. Having a PCR machine in the lab (which we obviously do) does not help for sequencing on its own, you need a separate machine for that. There's also no need to sequence the whole genome, this is unnecessary as we can use some specific genes for species identification. Published data is available for these genes, so that would greatly help identification.

These are two animals that were already picture in the opening post, but here is the previous shot with the belly and eye shots together:
D auratus panama special, costa rica
E anthonyi, E tricolor
T corticale, M baroni, A dorsalis
