The auctex developers have fixed the issue, which will be available in
the next version of emacs (since reftex is bundled).

In the meantime, they suggested to add the following in a configuration
file:

#+begin_src emacs-lisp
(with-eval-after-load 'reftex-parse
  (defun reftex-using-biblatex-p ()
    "Return non-nil if we are using biblatex rather than bibtex."
    (if (boundp 'TeX-active-styles)
	;; the sophisticated AUCTeX way
	(member "biblatex" TeX-active-styles)
      ;; poor-man's check...
      (save-excursion
	(re-search-forward "^[^%\n]*?\\\\usepackage.*{biblatex}" nil t)))))
#+end_src

Best,

Alan
