Ircinia chupoensis, Sim et al., 2017 , pp. 101, 106, 107, Fig. 10.

Material examined. Chupodo, Yecho­ri, Chuja­myeon, Jeju-si, Jeju-do.

Remarks. Psammocinia chupoensis has been previously recorded in the genus Ircinia ( Sim et al., 2017) based on its skeletal structure, but P. chupoensis has cored primary and secondary fibres with sands throughout the sponge ( Fig. 6D, G ), whereas secondary fibres in genus Ircinia are not cored with sand. Therefore we reclassify Ircinia chupoensis to Psammocinia .
