Fallacies based on correlatives are:
The false dilemma or false correlative. Here something which is not a correlative is treated as a correlative, excluding some other valid possibility.
The fallacy of denying the correlative, where an attempt is made to introduce some other invalid option into what is a true correlative.
The fallacy of suppressed correlative, where the definitions of a correlative are changed so that one of the options includes the other, making one option impossible.
