Which Neka book is that Jean?
At your prompt --- ie, your mention of "the Neka book" (saved me searching) --- I opened up "Keris Bali Bersejarah", page 126, and I cannot find any mention of varying terminology in Bali & Lombok. That is not to say there is not, of course. There could be varying terminology if we walk from one side of the road to the other.
The KBB explanation of difference between Kusia & Kocet-kocetan is that Kusia does not have tusks & its face looks like the head of a butterfly, whilst the Kocet-kocetan has a face that looks like an insect with tusks or a horse with tusks.
Neka produced a few books, so maybe his explanations change depending on what he had for breakfast.
Actually, these forms do not represent bugs, or completely developed insects, they represent pupa or chrysalis, the stage before a bug becomes a bug, as such they represent change, what that change is can be interpreted in a number of ways.
