Fig. 1. A in Systematics Of The Indo-West Pacific Broad-Fronted Fiddler Crabs (Crustacea: Ocypodidae: Genus Uca)

Fig. 1. A Bayesian inference (BI) tree of the Indo-West Pacific (IWP broad-fronted (BF) fiddler crabs (subgenera Austruca, Paraleptuca and Cranuca) and the comparative taxa (the American Minuca and Leptuca, the eastern Atlantic Afruca, and IWP narrow-fronted Tubuca, Australuca and Gelasimus), based on the combined 16S rRNA, cytochrome oxidase subunit I genes (COI) and 28S rRNA. For the details of specimens see Table 1. Probability values at the nodes represent support values for BI and maximum likelihood (ML). The doted lined block means the Uca lactea complex. For the clade of "Minuca & Leptuca", the species names with gray block belong to the subgenus Minuca, and the remaining species belong to the subgenus Leptuca.
