Template:GetCategory4

The template is a subtemplate of Template:CategoryMembers2a and a different version of Template:GetCategory. It uses 2 parameters, e.g.

{{Template:GetCategory4|Cotton leaf curl Gezira virus|Begomovirus (genus)}}

and returns the category name only if the found category is not equal to the 2nd parameter. That means in the above example it returns "Cotton leaf curl virus" (a subcategory of "Category:Begomovirus (genus)"). However, for "Abutilon mosaic virus" it returns this parameter because the page is directly under "Category:Begomovirus (genus)".
