that's easy!

FibI = fun
  (X,_) when X<1 -> throw(badarith);
  (1,_) -> 1;
  (2, _) -> 1;
  (X,FibI) -> FibI(X-1,FibI)+FibI(X-2,FibI)
end,
Fib = fun(X) -> FibI(X, FibI) end,
Fib(10).


it produce correct result -- 55.
So, you just should pass it to itself, and if you must use one-arg fun (for example, to pass it to somewhere), make additional fun that will call real fun with additional arg.
