Macaronesian islands as promoters of diversification in amphipods: The remarkable case of the family Hyalidae (Crustacea, Amphipoda)
The north‐east Atlantic (NEA) is an important and complex biogeographic region with a very rich marine fauna. However, little is known about the role of the Macaronesian islands in the evolutionary history and diversification of marine inver-tebrates in the NEA. Among the amphipods, the members of t...

The north‐east Atlantic (NEA) is an important and complex biogeographic region with a very rich marine fauna.
