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 for...
