It looks like for now all jurs are considered one genetic species but I am looking forward to reading more posts and opinions here and in other threads, especially those based on science, not so much guesswork.
Science moves at its own pace. There used to be just one giraffe catfish - Auchenoglanis occidentalis. As of a couple years ago, there is ~ a dozen species in that genus. Same with the electric cats - all used to be considered Malapterus electricus, now there is 19 of them.
