Table 1. Comparison of mean (± SE) corallite and radial elements dimensions (mm) and counts among Pavona giannii sp. nov., Pavona chiriquiensis, and Pavona varians. Character names, measurements and counts for P. chiriquiensis and P. varians are derived from Maté (2003: table 6) retaining the original number of decimal places used therein.
