Tentative representation of Madracis species diversity in the Caribbean and West Atlantic, including phylogenetic relationships (topology based on coalescent-based SNAPP analyses), in situ images of colony shape, SEM-images of corallite details, plus several diagnostic life history and ecological traits. Figure includes recognized Madracis species (names in black and colourful boxes in full line stroke) and putative new species (names in white and dashed line stroke) emerging from the present analyses. The accepted Madracis pharensis from the Mediterranean Sea (MED SEA) is added as reference. Corallite data from Mediterranean Sea Madracis pharensis (MED SEA) obtained from Benzoni et al.67, and symbiont type and depth distribution from Goodbody-Gringley et al.92. Reproductive period and symbiont acquisition strategy for Caribbean Madracis are based on pers. obs. (P. R. Frade and P. Bongaerts) and refer only to Curaçao. Relative position of candidate new species within Madracis pharensis in the Madracis tree are based on the Neighbour-Joining tree. For the “deep” Madracis pharensis lineage 2, only the Bermuda form is shown; the Curaçao form has substantially different corallite dimensions (see Fig. 3). Underwater photos by Pedro R. Frade.
