Porites branneri is distinguished morphologically by the presence of pali
and the absence of a columella tubercle.
For quantitative and qualitative keys to distinguishing western Atlantic
and Caribbean Porites species using morphological characters see:
Jameson SC (1997) Morphometric analysis of the Poritidae (Anthozoa:
Scleractinia) off Belize. Proc 8th International Coral Reef Symposium,
(If anyone would like a reprint just send me a stamped self addressed
envelope and I'll pass one along.)
Regarding the species controversy: Using electrophoresis, fixed allel
differences were found among P. astreoides, P. porites, P. furcata, P.
divaricata, P. colonensis and P. branneri off Panama by Weil (1992)
confiming they are distinct species.
Using the genetic results of Weil (1992), Jameson (1997) shows these
valid species can be distinguished using various
morphological/morphometric techniques and discusses what characters are
reliable in morphological analysis.
