Two ncw species of the family Pterastericolidae which inhabit starfish arc dcscribcd. Pterastericola bergensis sp.n. from thc oesophagus and cardiac stomach of Psilaster andromecla has posterior gonopore and lateral vitellaria. Pterastericola asamushii sp.n. from the pyloric caeca of Astropecren scopurius has unciliated epithelium postcriorly and an anterior gonopore. A cladistic analysis of thc phylogcny of the Pterastcricolidae is presented. The withdrawal of the genus Trilohorhynchus is proposed.
