Guys, I was able to solve without changing Json's class, i used this code:
  
List<ConsultationBeneficiaryModels.JSON2Apex> results = 
  (List<ConsultationBeneficiaryModels.JSON2Apex>)
  JSON.deserialize(
    jsonString, 
    List<ConsultationBeneficiaryModels.JSON2Apex>.class
  );
I was doing this:
  
ConsultationBeneficiaryModels.JSON2Apex response = (ConsultationBeneficiaryModels.JSON2Apex) System.JSON.deserialize(resp.getBody(), ConsultationBeneficiaryModels.JSON2Apex.class);
