A New Species of Predatory Nudibranch (Gastropoda: Trinchesiidae) of the Coral Pavona decussata.

ABSTRACT: Some nudibranchs are predators of scleractinian corals, but little is known about their diversity. Here we describe Phestilla fuscostriata sp. nov., the first species of nudibranch that preys on Pavona decussata, a structure-forming agariciid species in the South China Sea. This new species has a white body with brown pigmentation on the dorsum and cerata, and exhibits excellent mimicry by matching the colour of its coral host. The nudibranch lays crescent-shaped egg masses on the coral surface, where the embryos develop and hatch in 2-3 weeks. This new species possesses a large number of cerata that are arranged in widely-spaced rows, with each row having one dorsal ceras and zero to several ventral cerata, which distinguishes it from all other congeneric species.
