In this study, we focused on Acropora cytherea and A. hyacinthus , which have one of the highest potentials for interspecific fertilization. Using sequences of a nuclear intron, we performed phylogenetic and nested clade analyses (NCA). Both species were polyphyletic in molecular phylogenies, but the NCA indicated that they constitute statistically distinguishable lineages. Phylogenetic analysis using an intergenic region of the mitochondrial DNA (mtDNA), was inconclusive because of low levels of variability in this marker. The position of these two species differed between the nuclear DNA (nDNA) and mtDNA phylogenies and was also at odds with a cladistic analysis based on morphology. We conclude that despite the potential for high levels of hybridization and introgression, A. cytherea and A. hyacinthus constitute statistically distinguishable lineages and their taxonomic status is consistent with the cohesion species concept.</style></abstract><issue><style face="normal" font="default" size="100%">8</style></issue><notes><style face="normal" font="default" size="100%">Addresses:Marquez LM, Inst Venezolano Invest Cient, Ctr Ecol, Apartado 21827, Caracas 1020, VenezuelaJames Cook Univ N Queensland, Townsville, Qld 4811, Australia</style></notes><label><style face="normal" font="default" size="100%">6140</style></label></record></records></xml>
