Phylogeny of Anolis roquet and associated species. This Bayesian tree shows the Barbadian species, A. extremus, is the sister lineage to central Martinique and is nested within the phylogenetically deeper divisions of A. roquet from the precursor islands, which are now in secondary contact. The terminal node numbers are the locality codes for Martinique in Thorpe & Stenson (2003) and Barbados in Thorpe et al. (2005b), which are followed by alphabetic codes for individual replicates, with E denoting A. extremus, and additional localities 93, S1 and S2 (located at UTM zone 20 coordinates E-720425/N-1630450, E-733300/N-1599225 and E-732157/N-1594585, respectively).
