ABSTRACT. – Ahermatypic corals are mostly distributed in the greater depth region in comparison with shallow areas while inter-tidal zones are representing very limited species diversity. The family Caryophylliidae harbors the maximum species of ahermatypic corals including a maximum of azooxanthellate corals also. Polycyathus chaishanensis Lin, Kitahara, Tachikawa, Keshavmurthy & Chen, 2012 is an endemic zooxanthellate caryophylliid coral of inter-tidal habitats of Taiwan. This present paper deals with a new distributional record of P. chaishanensis from a tidal pool of Andaman and Nicobar Islands as a new addition to Indian waters.
