Remarks. The molecular analyses ( Fig. 2 View Fig ) reveal one major clade containing all the Tubuca and Australuca species. Although the Australuca species do form a distinct subclade, their inclusion causes Tubuca , as presently conceived, to become paraphyletic. Thus, in order to maintain Australuca as a separate genus, we would have to further split Tubuca and this seems unjustified at this time. We therefore treat Australuca Crane, 1975 , as a junior synonym of Tubuca Bott, 1973 , as the latter has nomenclatural priority. This revised concept of Tubuca makes it the most speciose genus in the IWP, with 21 species. Although the genus is widely-distributed in the IWP, it does not extend as far as the eastern margin of Polynesia, where only Paraleptuca and Gelasimus species occur ( Poupin & Juncker, 2010; Fig. 4 View Fig ).

Fig. 2. A Bayesian inference (BI) tree of the family Ocypodidae and outgroups, based on the combined 28S, 16S and COI markers. The solid circle at the node means it is strongly supported by both BI (≥ 90) and ML (≥ 70); and the open circle means only one method is strongly supported. Name of species or genus quoted means it is suggested as a synonym in this study.
