One specimen. ZMBN117065, POD, 11 May 2014 , 16m, 32mm . Habitats. Subtropical rocky reef. Occurrences. Ponta do Ouro. Geographic distribution. Indo-west, central Pacific. Hawaii ( Brunckhorst 1993 ; Gosliner et al . 2008), French Polynesia ( Brunckhorst 1993 ), Japan , Papua New Guinea , Malaysia , Indonesia , Vietnam , Marshall Islands , Oman , Maldives (Gosliner et al . 2008), British Indian Ocean Territory ( Yonow et al . 2002 ), India ( Apte 2009 ; Remakrishna et al. 2010), Mauritius , Réunion Island ( Brunckhorst 1993 ) and Mozambique . Remarks. This species has several pink longitudinal ridges formed by rounded tubercles. The foot sole is grey and the oral tentacles are pale grey ( Brunckhorst 1993 ). This species resembles P . zeylanica but it can be distinguished in the field by its ventral colouration and smooth tubercles. This species is likely to be part of a species complex as the ridges are more frequently interrupted in Pacific Ocean specimens than in Indian Ocean animals (Gosliner et al . 2008). The collected specimen exhibited two mid-dorsal ridge interruptions posterior to the rhinophores.
