I reckon I'm with you on this one Pak Boedhi. 
 
I only ever heard kelap lintah used by anybody for waved gonjos for years and years. 
 
Then a few years back I started to see all these other names in print, but all the people I knew still called all the waved gonjos of whatever type, "kelap lintah". 
 
I think that probably "kelap lintah" has become the generic---or maybe was always the generic, and those extremely knowledgeable experts---one of which I am not--- delight in using other names to distinguish one type of waved gonjo from another. Of course, this tends to become a little bit confusing when many of these experts are unable to agree on what is "correct", and what is not.
