Preheat the oven to 350°. Combine the crabmeat, garlic, jalapenos, Monterey Jack cheese, Worcestershire sauce, hot sauce, salt and mayonnaise in a medium-size mixing bowl. Toss gently to mix. Spoon the mixture into a medium-size shallow baking dish. Sprinkle the Parmigiano-Reggiano evenly on the top of the crabmeat mixture.
