Species Account:

        Phestilla sp. 3 was photographed and collected by Atsushi Ono from beneath a head of Pavona coral* in the waters off Gahi Island, one of a series of islands in the Kerama Islands Group, which are located 30 ~ 40 kilometers west of the Okinawa capitol, Naha. The above image is used with Atsushi's kind permission. Atsushi reports (pers. comm.) collecting only the above single specimen but has seen in excess of ten animals from the Keramas.

Phestilla sp. 3 is similar to Phestilla sp. 2 depicted in Gosliner, Behrens, and Valdés (2008, p. 372). In reference to the photos by Atsushi on these pages, Gosliner (pers. comm.) believes these are juveniles of Phestilla sp. 2 (2008, p. 372). In addition, I've added a second page showing five additional individuals on Pavona coral.

        Previously, three described Phestilla species have been featured on these pages, as well as two previously unknown Phestilla species. These species are:

  • P. lugubris
  • P. melanobrachia
  • P. minor
  • P. sp. 1
  • P. sp. 2
  • * Pavona coral: a member of the family Agariciidae. Most species of Pavona corals are widespread in the Indo-Pacific.
