A new species of Haliclona (Flagellia) Van Soest, 2017 (Porifera, Demospongiae, Heteroscleromorpha) from the Gulf of St. Lawrence, Canada
Haliclona (Flagellia) Van Soest, 2017 is a recently erected subgenus characterized by the presence of flagellosigma microscleres which are often distinctive between species (Van Soest 2017). Members of the taxon also have normal sigmas within a confused skeleton formed by oxea megascleres. The subge...
