Limenandra Haefelfinger and Stamm 1958是风蝗科的一个小属，在本文之前仅有Limenandra nodosa Haefelfinger and Stamm 1958和Limenandra fusiformis Baba 1949两种。虽然最近大多数作者认为Limenandra是Baeolidia Bergh 1888的初级同义种，但最近的分子研究已经证明了它的单系地位，并拒绝了模式种L. nodosa的热带分布。本文对已知的Limenandra物种进行了回顾和补充形态学资料，并描述了三个新种：来自印度太平洋的Limenandra barnosii sp. nov和Limenandra rosanae sp. nov因其鲜艳的色彩图案而很容易与其他Limenandra物种区分，而来自印度太平洋的Limenandra confusa sp. nov与大西洋和地中海的L. nodosa非常相似。这五个物种在颜色、角状体的大小和纹饰、鼻乳头、生殖系统的细节和唾液腺的数量上都有所不同。此外，根据根状和半花托形态的差异，可以很容易地将Limenandra与其他aeolidides科区分开来。
Limenandra Haefelfinger and Stamm 1958 is a small genus within the Aeolidiidae with, until this paper, only two species: Limenandra nodosa Haefelfinger and Stamm 1958 and Limenandra fusiformis Baba 1949. Although most recent authors have regarded Limenandra as a junior synonym of Baeolidia Bergh 1888, recent molecular studies have demonstrated its monophyletic status and have rejected the circumtropical distribution attributed to the type species, L. nodosa. The present paper reviews the previously known species of Limenandra with additional morphological data and describes three new species: Limenandra barnosii sp. nov. and Limenandra rosanae sp. nov. from the Indo-Pacific are easily distinguished from all other Limenandra species by their vivid and bright colour patterns, while Limenandra confusa sp. nov., also from the Indo-Pacific, is very similar to the Atlantic and Mediterranean L. nodosa. The five species differ in colouration, the size and ornamentation of the cerata, the rhinophorial papillae, details of the reproductive system and the number of salivary glands. Additionally, Limenandra can be easily distinguished from other Aeolidiidae based on differences in the radular and receptaculum seminis morphology.
