Many of these were observed on Avrainvillea algae on the black sand slopes of several Tulamben sites. These are similar to but not quite a match for the ones we are calling Costasiella vegae from the Marshall Islands, but are tentatively identified as such by the blue spots on the cerata. It may in fact be a variation of one of the color forms of Costasiella kuroshimae in Gosliner et al (2018).
Those below were from Puri Jati.

This one may not be the same species as it lacks the black and blue spots on the cerata.
