Plots of morphometrical measurements of Lepidophyllia (Heterastraea) microcalix sp. nov. A Histograms of morphometrical measurements (calicular great diameter, calicular small diameter, thickness of the wall, distance from corallite to corallite, number of septa and septal density). B Morphospace plot of corallites from studied colonies computed with PCA (co-variance matrix) on the two calicular diameters (great and small), thickness of the wall and distance from corallite to corallite. Each dot color represents one colony. The two first principal components explain 92.9% of the total variance.
