This is exactly why the scientific nomaclature system was developed.
Scientific or latin names are essential so as fanciers from different countries can understand what species they are dealing/talking about. It was devised by a Swedish scientist named Carl Linné. Every organism weather it be plant or animal has been classified acording to this system. Since I am interested in killifish I will explain in those terms.(but it holds true for whatever species you use.
The first word in the name is capalised and denotes the Genus of the organism, the second word which is in lowercase indicates the species. The species can be subdivided again, and the third word signifies the subspecies. Finally there is the location which is capatilised;
Fundulopanchax - gardneri - nigerianum - Misaje
Common names are often varied and misleading.
