Species trees of Dongsha Atoll Sinularia clades 4 and 5C. Cloudograms illustrate the best species delimitation models (DAPC+ 1) for both clades inferred from bi-allelic SNP data [a clade 4: 6,236 SNPs and b clade 5C: 8,022 SNPs); m0.75 datasets] using SNAPP species tree analyses. The maximum clade credibility tree and congruent trees are in blue. Trees with different topologies are in red and green. Posterior probabilities at internal nodes > 95% unless indicated
