"Comment from Nathalie Yonow: Possibly. Normally in Phyllidiella rudmani the black lines do not meet in front of the rhinophores, but I can’t think of any other species except Phyllidiella krempfi, which has that distinctive line in front of the rhinophores. However, Phyllidiella krempfi usually has more black. The black frontal line and compound tubercles seem to me more like Phyllidiella krempfi but the all black rhinophores are NOT Phyllidiella krempfi. "
