Well that trader is very knowledgeable so I'm not sure it is a tradename. I know that most non-common fishes are not being imported from africa and can mostly only be found tank bred due to deteriorating conditions. I remember reading an article a month ago about there being many interesting fishes that have left the hobbist trade but can no longer be obtained due to dangerous conditions in africa.The fact that only one trader has had them on their stock list I would almost think it's a tradename that importer coined themselves. What I find interesting though, is that they say on that website the fish are tankbred from the Czech Rep. and there are no imports from Africa to Europe or the Americas. I even did a search in Czech, nothing.
The picture they have on their website looks a bit strange for a Pelvicachromis, maybe it's closer related to Nanochromis, Enigmatochromis or Wallaceochromis.
I don't even think it's misidentified proper, but rather just basically unidentified/unclassified.Anyway my tought is that it was a fish that had been obtained a while ago and captive bred but you might be correct and it is mis identified.
Quite possible. The article i mentioned above (should find the link) talked about a lot of different species of kribs and many unclassified fishes in the region as well as for the impossibilities for scientists to get into the area to study them due to safety issues.I don't even think it's misidentified proper, but rather just basically unidentified.
