This is a known bug:
http://comments.gmane.org/gmane.emacs.auctex.devel/3692
This thread also suggests a fix:
#+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
