The photo used in this volume is credited to Newman and Andrew Flowers. The id section specifies that the color of the marginal band is yellow cream with a bright orange rim..
There are clearly a lot of undescribed polyclads out there. In a field this little known, questions of what constitutes color variation within a species (or not) are not always going to have hard and fast answers.
The distribution ranges initially given for recently described species will also require revision as new examples are found. (Remember when people thought Pygmy Seahorses (H. barbiganti) could only be found a few places in Eastern Indonesia?)
We're just beginning to understand the way that the Indonesian Throughput and other currents affect distribution of species, endemism and genetic exchange within the larger Indo-Pacific area.
TNC's Southeast Asia Center for Marine Protected Areas has recently come up with a list of 11 distinct ecoregions within the larger Indo-Pacific "Coral Triangle" (encompassing all of Indonesia and the Philippines, plus most of PNG and part of Malaysian Borneo). It's based in part on earlier work by Gerry Allen. Within these eco-regions, they are identifying highly inter-connected "functional seascapes" which in turn will help in macro-level planning for establishing MPAs. These schema can also be very useful to divers and u/w photographers in terms of thinking about the patterns of marine biodiversity in this region.
For me, all this is a big part of the excitement of the Indo-Pacific - you can't always just look it up. There's a real possibility of seeing (and photographing) a previously undescribed species on almost every dive.
