There is probably no real difference between A. bitaeniata "Bauana" and "Cacadola". These names only refer to collecting locations. Do not expect all Bauana to be as red as yours. Most specimens from the Rio Bauana are more blue.
Good to see another apisto collector from Hong Kong here, welcome, Mr. Apistoworld(HK) ^.^
I reckon that Mike is right with which the collecting
locations are just presented for collectors' reference.
In addition, it is a kind of branding/labeling practice to
entice hobbyists to buy. We all know that the same species
collected in the same location can show significant differences,
e.g., for A. paucisquamis, we have different color morphs
in the same locality... ^.^ So, the use of collecting location
need not be a good way to differentiate these fish...
but is very popular nowadays in the market...
