I don't know the scientific name of the dwarf, the whole Pyxicephalus species is messed up.
Yes they both species have the same appearance as babies bust you can tell them appart. They 2 outside green stripes of the young edulis are not as long as the adspersus. They stripes reached not the eyes. But a big differens of the edulis and adspersus is that the adspersus (babie and adults) have a sort of eyebrow above the eyes. The edulis don't have them.
Edulis babies are getting more brouwnish/grey when get bigger but the adspersus babies becomes more and more green when they get bigger.
I put some pics of a edulis babie growing in 3 months
