This appears to be the animal figured in Gosliner et al (2018) as Chromodoris sp. 5. Similar to Goniobranchus reticulatus, they differ in the changing pattern of reticulation in different parts of the dorsum, the distinct orange margin and the red edging to the gills. The few specimens we saw were smaller than typical G. reticulatus. The Bethlehem channel was a good place to see these.
