Other external morphology characteristics

Live specimens ranged in length from 10-29 mm and mean size was 14 mm.
    Anteriorly, each white ridge continues over each of the rhinophoral pockets to the anterior margin of the mantle. Three narrow, longitudinal black lines run between the ridges and the white marginal area. Small black spots occur along the white marginal areas.
    The rhinophores are white and each clavus possesses 12-14 lamellae (specimens greater than 15 mm).
    Ventrally, the hyponotum is white with small black spots along its margin. The gills, foot and oral tentacles are white. There are small isolated, black spots along the side of the foot. The fused white oral tentacles are small with indistinct lateral grooves.
    Etymology : The name for this species is derived from its type locally, the Phi Phi Islands, 48 km to the south east or Phuket, southern Thailand
