PAGENAMEBASE
This template returns the current {{PAGENAME}} minus (text in parentheses) or the final set of parentheses where more than one set exist.
{{PAGENAME}}
e.g. {{ PAGENAMEBASE }} on page Chiton (genus) returns Chiton
{{ PAGENAMEBASE }}
Can also pass an optional page parameter:
{{PAGENAMEBASE|foo (bar)}}
{{PAGENAMEBASE|foo bar}}
It is not to be confused with {{BASEPAGENAME}} , which is a magic word that strips subpages, not parentheses.
