F05587C4FFD09F66FCCA3F42FE54F8EB.taxon	discussion	Remarks.

F05587C4FFD29F60FF733F9CFEA9FB36.taxon	etymology	Etymology. This new species is named, massa, after the lumpy skeletal structure of the sponge.	en	Kim, Young A, Sim, Kyung Jin Lee and Chung Ja (2018): Psammocinian sponges (Demospongiae: Dictyoceratida: Irciniidae) from Korea. Journal of Species Research 7 (4): 340-347, DOI: 10.12651/JSR.2018.7.4.340
F05587C4FFD29F60FF733F9CFEA9FB36.taxon	discussion	Remarks. Psammocinia massa is similar to P. gageoensis in thick skeletal structure, but there is a big difference in the shape of the sponge. Primary and secondary fibres of this new species are lumped together in a thick mass through numerous areas. Branched secondary fibres in P. gageoensis have a very complicated fasciculate shape in skeletal structure.	en	Kim, Young A, Sim, Kyung Jin Lee and Chung Ja (2018): Psammocinian sponges (Demospongiae: Dictyoceratida: Irciniidae) from Korea.

F05587C4FFD49F60FCCA3CEEFBBEF91A.taxon	discussion	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. 6 D, G), whereas secondary fibres in genus Ircinia are not cored with sand. Therefore we reclassify Ircinia chupoensis to Psammocinia.	en	Kim, Young A, Sim, Kyung Jin Lee and Chung Ja (2018): Psammocinian sponges (Demospongiae: Dictyoceratida: Irciniidae) from Korea.

F05587C4FFD49F60FF733CE9FC23FB39.taxon	discussion	Remarks. Psammocinia vemis is similar to P. mosulpia in skeletal structure, but differs in size of cored sands in primary fibres.	en	Kim, Young A, Sim, Kyung Jin Lee and Chung Ja (2018): Psammocinian sponges (Demospongiae: Dictyoceratida: Irciniidae) from Korea.
