Due to the complexities caused by the ambiguous meaning of the term warbler, which at the moment includes 5 separate scientific families, I give below a further clarification of some terms as used on this site, other sites may use different terminology.
Sylviid-warblers = all warblers of the category - Warbler Sylvia
Sylviid-warblers+ = Sylviid-warblers plus all other species in the Family Sylviidae = all Warbler5 = Sylviidae
This is in keeping with the usual way Families are headlined in English, eg for the present Family usually written...
Sylviidae - Sylviid-warblers and allies - and which on this site is written as...
Sylviidae - Sylviid-warblers+
which I think is a very convenient way to indicate a family group in English by adding a + to the usual characteristic sub-family member, and is worthy of widespread use because of its simplicity and clarity, to make clear the reference to both the sub-family and the full scientific family in English rather than Latin.
The other categories are self explanatory.
