We have found these in the Padangbai area and on the Liberty wreck at Tulamben. This group remains a bit of a puzzle, with some degree of intergrading in color patterns between Hypselodoris apolegma and what we are considering H. iba. One key external feature we have used to try to distinguish H. apolegma from similar species is the zone of speckles that runs between the purple or pink dorsal color and the wide white margin, essentially softening the border between those two colors. However, the extent of this zone appears to be somewhat variable between specimens. The first two photos clearly fit the description of H. apolegma, and the following two larger, brighter pink specimens seem to do so as well.
These two large individuals were mating next to the Liberty shipwreck.
This one was in the Padangbai area.
