Ultrametric tree obtained with Beast using the combined sequence, excluding the Sardinian species. Black circles, well supported nodes (see Fig. 1, Additional file 3) constrained to be monophyletic. Numbers inside nodes, age estimate (MY), using the separation of Bathysciola zariquieyi from its sister (red node), with a prior age of 37.9MY (see text and Additional file 5).
