ah ok i get what you mean the last genus i was working on had a similar situation particularly distinct groups of species got their sub genera and everything else was crammed together higgledy piggledy eventually they'll be no more new species being discovered and this job will be a lot easier i'm a political science student and this is similar to politics everyone has their different view of what is isn't appropriate classification and it is unlikely to ever be settled you have studies claiming that x is a species later revisions claiming x is a subspecies of y genetic tests proving x is distinct from y and then occular patterns and physical appearance showing x is related to y it goes on and on lds
