There is not as much difference between C. facet uni, C. autochthon, 

 and C. ohlongum as there is between a large series of either Crenicichla 

 lepidota or Geophagus hrasiliensis. The only difference is a free or an 

 interrupted fold, and there are all stages between these two extremes. 

 These species are found in the same localities. Several other species 

 of cichlids have both a free fold and an interrupted fold. In view of 

 all this these names must be considered as synonyms.
