Members of the nudibranch genus Phestilla are common predators of
scleractinian corals, but currently this genus has 10 described species
only. Here we describe Phestilla
goniophaga sp. nov., the first formally named predatory
nudibranch species of the stony corals from the genus Goniopora. The new species can be
distinguished from its congeneric species by the large number of long
cerata (up to 16 rows and 23 cerata per row), and white rounded hump on
the notum. The hump resembles the mouth of the coral poly, while the
cerata resemble the coral tentacles. The egg masses of P. goniophaga sp. nov. are unique
among Phestilla spp. egg
masses in being bright orange in color, and forming a coiled ribbon.
Analysis of the COI, 16S rRNA and H3 genes of P. goniophaga sp. nov. also showed
that this species is distinct from other congeneric species.
Key words: Coral, Coral-eating,
Corallivory, Mollusca, Phestilla.
