Custom entity model error

Hello,
I've added a creature model imported from blockbench, but when I launch the client I get this error:
error: cannot find symbol 
public class Modelphantomecorrompue<T extends phantome> extends EntityModel<T> {
public void setupAnim(phantome entity, float limbSwing, float limbSwingAmount, float ageInTicks, float netHeadYaw, float headPitch) { 
                         ^ 
 symbol: class phantome 
 location: class Modelphantomecorrompue<T> 
 where T is a type-variable: 
   T declared in class Modelphantomecorrompue
