This unknown Rostanga is known from five specimens found in Halimeda patches on Kwajalein's eastern lagoon reef at depths of 9-10m and ranging in size from 8 to 19mm. The first one figured below measured 15mm in length. The top photo was taken in the field using a Nikon DS80. The lower one was shot with a Dino-Lite digital microscope using LED lighting. This species may also include the one figured under Rostanga sp. e403. An animal very similar to this is in Gosliner et al (2008) as Doris sp. 7.
These two specimens were found in a lagoon Halimeda patch at a depth of about 8m on the night of 30 August 2008.
The specimen below was found on 25 May 2009 at a depth of about 8m in a Halimeda patch on a Kwajalein Atoll lagoon reef. It laid the orange egg mass in captivity.
