The validity and position of the Indo Pacific genus Phestilla Bergh, 1874 (Fionoidea: Trinchesiidae) have been subject of some controversy as a result of several recent studies, which have sequentially synonymized or re-established it. At present, the genus includes eight valid species, the most of them described in the nineteenth and twentieth centuries, and all but one feeding on scleractinian corals of four genera: Porites Link, 1807 (Poritidae), Tubastraea Lesson, 1830, Dendrophyllia Blainville, 1830 (Dendrophylliidae) and Montipora Blainville, 1830 (Acroporidae). The discovery of an unknown Phestilla species feeding on Pavona explanulata (Lamarck, 1816) (Agariciidae) in Koh Tao, Thailand, motivates this work, in which this new species is described providing morphoanatomical and molecular characters. In addition, its systematic position and ecological significance as coral parasite are discussed.

来自泰国湾的一种新的以珊瑚为食的裸udi科动物(软体动物:腹足纲)

由于最近的几项研究的结果,印度太平洋属Phestilla Bergh,1874年(Fionoidea:Trinchesiidae)的有效性和位置受到了一些争议,并相继对其进行了同义词或重新建立。目前,该属包括8个有效种,大多数描述于19世纪和20世纪,除了一个属以外,其余的全部以4个属的巩膜珊瑚为食:Porites Link,1807年(Poritidae),Tubastraea Lesson,1830年,Dendrophyllia Blainville, 1830年(Dendrophylliidae)和Montipora Blainville,1830年(Acroporidae)。以Pavona explanulata为食的一种未知费斯蒂拉物种的发现(泰国,涛岛,Lamarck,1816年)(Agariciidae)推动了这项工作,其中描述了这种新物种,提供了形态解剖学和分子特征。此外,还讨论了其作为珊瑚寄生虫的系统地位和生态意义。
