Polymastiidae (Demospongiae: Hadromerida) with ornamented exotyles: a review of morphological affinities and description of a new genus and three new species
All polymastiid sponges displaying ornamented exotyles are reviewed and their morphological affinities are reconsidered. The study embraces all known species of Proteleia , Sphaerotylus , Trachyteleia and Tylexocladus as well as several species of Polymastia . A new genus, Koltunia , is established...
