Alona weinecki Studer, 1878

Originally described from Kerguelen ( Studer 1878), Rühe (1914) showed that Ekman’s (1905) Falkland Island record of Alona bukobensis v. subantarctica was in fact A. weinecki . Similarly, the records of A. rectangula from South Georgia and the South Orkney Islands ( Dartnall and Heywood 1980) refer to A. weinecki ( Paggi 1987; Frey 1988). It was then supposed that this species was restricted to the subantarctic islands, but Dumont and Martens (1996) have subsequently recorded it from Easter Island, and South Island, New Zealand. The morphology of the specimens examined in this study, especially the shape and armature of the post-abdomen ( Figure 10 ) and size, 0.5 mm, corroborate that they do belong to this species.
