With the complexity of the family Phyllidiidae and the problems of identification in the Indo-West Pacific, the story of the Red Sea species continues to unfold. One new species and one new record are added to the Red Sea fauna, both belonging to the genus Phyllidiella. Phyllidiella amphitritesp. nov. is described from a single specimen from the northern Red Sea and clearly differs from all species of Phyllidiella in having pale yellow pigment on the tubercles. Phyllidiella zeylanica is newly recorded from the Red Sea with five specimen records and several photographed individuals; other than this, it has a western Indian Ocean distribution. Phyllidia schupporum was collected for the first time since its original description; because its distribution is now extended to the Persian Gulf, it is no longer considered endemic to the Red Sea. The distribution of the Red Sea endemic Phyllidia dautzenbergi is extended northwards to Hurghada, Egypt. A small specimen of the endemic Phyllidiopsis sinaiensis was found at 214–237 m depth just at the mouth of the Red Sea, which is a bathymetrical range extension from its previous shallow coral reef records. The identifications of other species are revisited. A new species of Paradoris is described as Paradoris hypocritasp. nov., differing from the well-known but localised West Pacific P. liturata which also resembles a phyllidiid. This new species was recorded many years ago by published photographs, and it is relatively common in the Red Sea, evidenced by several specimens and additional photographs. It is described herein, and is considered a Red Sea endemic, differing from both the unnamed Indian Ocean species and the named Pacific species.

红海 Opisthobranchia 6: Phyllidiidae 和它们的拟态拟态：新物种和新记录 (Heterobranchia, Nudibranchia, Doridina)

由于 Phyllidiidae 科的复杂性和印度-西太平洋的鉴定问题，红海物种的故事继续展开。红海动物群中增加了一个新物种和一个新记录，它们都属于 Phyllidiella 属。Phyllidiella amphitritesp。十一月 由来自红海北部的单个标本描述，与所有 Phyllidiella 物种的明显不同之处在于结节上具有淡黄色色素。Phyllidiella zeylanica 是红海新记录的，有五个标本记录和几个被拍照的个体；除此之外，它还有西印度洋分布。Phyllidia schupporum 自其原始描述以来首次被收集；因为它的分布现在扩展到波斯湾，它不再被认为是红海的特有种。红海特有的 Phyllidia dautzenbergi 的分布向北延伸至埃及的赫尔格达。在 214-237 m 深度的红海口处发现了一个地方性 Phyllidiopsis sinaiensis 的小标本，这是其先前浅珊瑚礁记录的测深范围扩展。重新审视其他物种的鉴定。Paradoris 的一个新物种被描述为 Paradoris hypocritasp。11 月，不同于众所周知但本地化的西太平洋 P. liturata，后者也类似于 phylliidid。这个新物种是多年前通过出版的照片记录的，它在红海相对常见，有几个标本和其他照片证明了这一点。它在本文中有描述，被认为是红海特有的，不同于未命名的印度洋物种和命名的太平洋物种。
