Myxilla tarifensis sp. nov. (Porifera, Poecilosclerida), with remarks on the genus Myxilla in the Strait of Gibraltar (Iberian Peninsula)

“…For a few years, a multidisciplinary research project has been in progress in this zone and nearby areas in order to catalogue fauna. During this research the existence of little known species, including some species new to science, has been reported (Naranjo & Garcia-Gomez, 1993;Medel et al, 1993;Lopez de la Cuadra & Garcia-Gomez, 1993). However, knowledge of littoral sponges from the area is currently very scarce in spite of the efforts during the last few years, which include only a few general studies (Pansini, 1987;Maldonado, 1992;Carballo & Garcia-Gomez, 1994a,b;Boury-Esnault et al, 1994) and some of a more specific content (Rutzler, 1973;Carballo et al, 1994).…”
