The World Amphipoda Database: history and progress

We provide an overview of the World Amphipoda Database (WAD), a global species database that is part of the World Register of Marine Species (WoRMS). Launched in 2013, the database contains entries for over 10,500 accepted species names. Edited currently by 31 amphipod taxonomists, following WoRMS priorities, the WAD has at least one editor per major group. All accepted species are checked by the editors, as is the authorship available for all of the names. The higher classification is documented for every species and a type species is recorded for every genus name. This constitutes five of the 13 priorities for completion, set by WoRMS. In 2015, five LifeWatch grants were allocated for WAD activities. These included a general training workshop in 2016, together with data input for the superfamily Lysianassoidea and for a number of non-marine groups. Philanthropy grants in 2019 and 2021 covered more important gaps across the whole group. Further work remains to complete the linking of unaccepted names, original descriptions, and environmental information. Once these tasks are completed, the database will be considered complete for 8 of the 13 priorities, and efforts will continue to input new taxa annually and focus on the remaining priorities, particularly the input of type localities. We give an overview of the current status of the order Amphipoda, providing counts of the number of genera and species within each family belonging to the six suborders currently recognized

Taxonomy based on science is necessary for global conservation

On the mysid crustacean genus Deltamysis (Mysidae: Heteromysinae), with a new species and a new record from Australia

The genus Deltamysis, in the tribe Mysidetini (Mysidae: Heteromysinae), previously contained a single species, D. holmquistae, before two additional species, D. nana and D. songkhlaensis, were transferred from Heteromysoides of the related tribe Heteromysini. A new member of the genus, D. lowryi sp. nov., found at the mouth of the Clarence River, New South Wales, in 1988, is described here from the Australian Museum collection. The collection also contained two specimens of D. holmquistae from the eastern Australian coasts of the Coral Sea and the Tasman Sea, not previously recorded from Australia. Deltamysis lowryi sp. nov. differs from the other three species of the genus by the structure of the telson, which has a wide, shallow cleft, armed with a number of spinules, and notably shortened subterminal spiniform setae. The diagnosis and the generic composition of the tribe Mysidetini, and the diagnoses of the genus Deltamysis and all its four species are updated. Deltamysis has so far been the only genus of the marine subfamily Heteromysinae diversifying in brackish estuarine water. The genus has a clear western Indo-Pacific natural occurrence, but has been introduced also to the Eastern Pacific and more recently to the Atlantic coasts of North America
