This Phyllodesmium is known from several specimens found under rocks on the tops of Kwajalein Atoll midlagoon pinnacles. Two were found on a on 21 November 2010, three more on 11 April 2011 and an additional three on 9 October 2012. The first two specimens at rest measured 25 and 23mm. It is similar in some respects to Phyllodesmium poindimiei, but there appear to be significant differences in color.
Below are two of the specimens found on 11 April 2011, which were also under a rock on a large midlagoon Kwajalein Atoll pinnacle. The three individuals, these two and one very small one, were clustered together. The medium-sized specimen below had a more golden yellow color.
Below is one of the animals found on 9 October 2012. It was carrying a copepod commensal just behind the rhinophores.
