I am inclined to agree with Richard, but there are other data that make me more cautious in general respect.
In this case, everything from the phenotypic aspect votes for nagyi. Not the dots in the ventrals only (as Richard points out correctly), but the whole ventrals which are very short with much shorter filaments than in alfredi. In fact the ventrals of nagyi are the strikingly shortest in all Licorice Gouramis. And finally it’s the stout appearance of the fish; nagyi are markedly stouter in their bodily shape than alfredi.
But although I am fairly sure from these phenotoypic arguments (and in this case related to that locations near Kota Tinggi in Western Malaysia), the newest general informations from the geneticists are really disturbing. Dr. Lukas Rüber (Bern) investigated a series of fish that all was sent as phenotypic linkei, but he found rather different genetic structures. Yes, I can remember that I have seen very different “linkei”: some with sivery body and fins and some with brownish body and fins, some with straight filaments of the ventrals and some with arrowed filaments, and some with many nice red dots around the black side-spots, and other without.
And the same holds for parvulus. We all remember Horst Linkes information of 2009/2010 that this species is the most widely distributed among all licorice gouramis. And there were small phenotypic differences, fish from Babugus looked different form fish from Tangkiling and other places. Now we learn from Lukas that he finds rather big genetic differences between his samples from different places. What does this mean? We don’t know presently.
All we can do at the moment is: wait and be cautious. The whole story of Parosphromenus has not been told already. There are surprises still possible. And that riddle around Kota Tinggi has not been solved, too. For if they are indeed nagyi: How is it possible that they occur there? Have they simply been overlooked formerly? And what happened to the alfredi? Are they still there? For all who love problems this is an exciting situation!
