"I hesitate calling this one Phyllidiella pustulosa, partly because of the obviously pink-edged anal opening. The way the middorsal pink pustules are set in circles around black centers resemble Phyllidiella annulata, although it not as distinctly annulated as specimens figured Brunkhorst's 1993 review of the Phyllidiidae. But Phyllidiella lizae might be closer than either of those other possibilities. I think I'd go with Phyllidiella lizae."
