Inirida are spotted, similar to notatus, but have only 8 bars like rotkeil. Since other severums have 9 bars, that would normally be one of the giveaways for these two fish (inirida and rotkeil). Also, Inirida is a river in Columbia. I haven't seen anything where sp. inirida have been officially described yet, hence the "sp" in front of their name, which would go away if or whenever they're officially described as a separate species, as would (or should) two different fish being sold under the name-- if that's the case. But identifying them would seem to be fairly straightforward, a spotted severum with only 8 bars from a specific river, Inirida in Columbia. Beyond that I don't know what other fish would (or should) be called inirida. Not to say another fish hasn't been sold under the name, just that I don't know why that would be the case.
