There are a couple of alternatives.

1) Create an alias of the parent's method and call it instead:

class Child < Parent
  alias parent_hello hello
  def _hello(name)
    parent_hello(name)
  end
end

2) use a method object to reference the parent's method:

class Child < Parent
  def parent_hello(*args)
    Parent.instance_method(:hello).bind(self).call(*args)
  end

  def _hello(name)
    parent_hello(name)
  end
end
