Phyllidia monacha
Photographed by: Ria Qorina Lubis
This small phyllidiid is characterised by 3, mid-dorsal, longitudinal ridges formed by tiny tubercles plus lots of small, simple tubercles on the flanks resembling those of Phyllidia coelestis. Colourwise the central area is orange and the crests of the ridges are white. On the flanks is a black line (either, simple and straight as in Indonesian specimens, or enlarged and wavy as in the animals from the Red Sea) outlined in white. These broad white halos/stripes are composed of large pigment granules resembling those of Phyllidia willani. The rhinophores are dark orange. This species is uncommon and it was previously only known from the Red Sea. There is a photo of a specimen from Flores in Debelius & Kuiter (page 270, middle of bottom row) -- Richard Willan
