Hi Bill,
Here are some photos of Rostanga lutescens from Enewetak Atoll, Marshall Islands, to add to the Rostanga collection. These animals were all small, ranging from about 12 to 19 mm. The few specimens found were all living under chunks of dead coral on shallow subtidal lagoon reefs at depths from about 2 to 5 meters.

I hadn't realised from your description (Johnson & Bertsch, 1985) just how translucent this species is. These photos are a very useful addition to the Forum
Best wishes,
