This appears to be Trapania sp. 6 in Gosliner et al (2015). Specimens have been found on two southern Kwajalein lagoon pinnacles. Each time, small groups of 3 or 4 individuals were on entoproct covered thin red sponge that was growing over colonies of Millepora coral that died during a bout of coral bleaching a couple of years previously. The largest specimens measured a bit more than 10mm.
