The checklist of Mysida and Lophogastrida of Greece was created within the framework of the Greek Taxon Information System (GTIS), which is one of the applications of the LifeWatchGreece Research Infrastructure (ESFRI) resuming efforts to develop a complete checklist of species recorded and reported from Greek waters. The objectives of the present study were to update and cross-check taxonomically all records of Mysida and Lophogastrida species known to occur in Greek waters in order to search for inaccuracies and omissions.

New information

The up-to-date checklist of Mysida and Lophogastrida of Greece comprises 49 species, classified to 25 genera.

The peracarid crustaceans Lophogastrida, Stygiomysida and Mysida were formerly grouped under the order "Mysidacea". Although these three monophyletic groups are now ranked as distinct orders of Peracarida (Meland and Willassen 2007, Meland et al. 2015), we have chosen to present mysids and lophogastrids under the same checklist, while no stygiomysids have been recorded so far from Greek waters. The most important contribution to the Greek records of the taxonomic group of "Mysidacea" has been made by Hatzakis (Hatzakis 1974, Hatzakis 1977, Hatzakis 1978, Hatzakis 1982) followed later on by Madurell and Cartes (2003) as well as Koulouri et al. (2013). "Mysidacea" constitute the dominant faunal component for the so-called hyperbenthos, which includes all swimming bottom-dependent organisms (mainly crustaceans) performing, with varying amplitude, intensity and regularity, seasonal or daily vertical migrations into the water column (Brunel et al. 1978). A large proportion of these animals are living within the benthic boundary layer (BBL) which is the portion of the sediment and the water column that is influenced by the sediment-water interface and characterized by strong gradients of flow as well as high concentrations of dissolved and particulate organic matter (Boudreau and Jørgensen 2001). Sampling these often highly mobile animals is not easy as they are caught occasionally by conventional benthic (e.g., grabs, corers) or pelagic (e.g. plankton nets) sampling gears (Eleftheriou 2013). Specially designed samplers, generally known as hyperbenthic or suprabenthic sledges, have been constructed, modified and used over the last 40 years for sampling these macrofaunal organisms, but there are still practical technical difficulties in the accessibility of this particular habitat (Mees and Jones 1997, Eleftheriou 2013, Koulouri et al. 2013). However, and when depth allows, these organisms can also be sampled by scuba diver operated "hunting" tools such as hand nets (e.g. Ledoyer 1968) or suction bottles (e.g. Chevaldonné et al. 2008).

A first attempt for creating a checklist of Mysida and Lophogastrida under the order of "Mysidacea" was carried out in the context of the “Greek Biodiversity Database” project (2005-2008), coordinated by the Department of Zoology, at the Aristotle University of Thessaloniki. The documented occurrence of these marine species in Greek waters was recorded in a database that was set up online in 2010. Although not completed, the database had not been updated since the closure of the project (2010). During the European project PESI, WoRMS/ERMS specially created the reference Koukouras (2010) for the list of marine species provided by the Greek Biodiversity Database. The aim of the present work was to present an updated checklist of Lophogastrida and Mysida of the Greek waters. For this purpose, older lists were updated and annotated according to the recent literature and current taxonomic status of the species.

Materials and methods

The Checklist of Mysida and Lophogastrida of Greece (Suppl. material 1​) was created within the framework of the Greek Taxon Information System (GTIS), one of the applications of the LifeWatchGreece Research Infrastructure (ESFRI), aiming at developing a complete checklist of all species reported from Greek waters (Bailly et al. 2016, this special collection). The general principles used for elaborating this Preliminary Checklist are given in Bailly et al. (2016). The checklist of Mysida and Lophogastrida of Greece was constructed based on the species records extracted from the dataset of WoRMS/ERMS for marine species. Then, all recent publications were reviewed and the species reported to date have been added to the list. The classification followed in the present checklist is the one proposed by the World List of Lophogastrida, Stygiomysida and Mysida (Mees and Meland 2012).

A total of 49 species, classified in 25 genera, makes up the updated checklist of Lophogastrida and Mysida of Greece. More specifically, the order of Lophogastrida comprises 2 species classified to 2 genera, while the order of Mysida comprises 47 species, classified to 23 genera. It is worth mentioning that Dactylamblyops corberai San Vicente & Cartes, 2011, a new mysid species was described from the deep Ionian Sea by San Vicente and Cartes (2011), revealing the limited sampling effort that has taken place for these particular taxa. It should also be noted that Chevaldonné et al. (2015) provided new molecular and distribution data on the poorly known cave mysid Harmelinella mariannae Ledoyer, 1989. A number of issues aroused during the thorough examination of the checklist of Mysida of Greece, specifically regarding the presence of the species Diamysis bahirensis (Sars G.O., 1877), Haplostylus magnilobatus (Bacescu & Schiecke, 1974) and Paramysis festae Colosi, 1921 in Greek waters. The material previously indicated as D. bahirensis by Hatzakis (1982) has been revised and assigned to D. lagunaris and D. bacescui (Wittmann and Ariani 1998, Wittmann and Ariani 2012). Therefore, further research is needed to verify the presence of this species in the Greek waters. The species H. magnilobatus has been included in the mysid species of the Aegean Sea according to Coll et al. (2010). However, the reference used for this record does not actually include this species in the Greek fauna (Hatzakis 1977). The species P. festae has been recorded in the Ionian coast of Sicily and in a brackish lagoon of Libya (Audzijonyte et al. 2008, Wittmann and Ariani 2011), but not yet in Greek waters. Moreover, further research is needed for the verification of the presence of the mysid species recorded by Koulouri et al. (2013) as Erythrops cf. peterdorhni Basescu & Schiecke, 1974 in the Greek waters. We should also note that when establishing the new rank Siriella gracilipes for part of what was called S. jaltensis, Wittmann and Wirtz (1998) reported the finding of S. gracilipes in the Aegean Sea. Finally, two provisional cryptic species of the complex taxon Hemimysis margalefi sensu lato were recorded from marine cave habitats from Corfu and Crete islands by using molecular techniques (Rastorgueff et al. 2014) and therefore, their taxonomic status needs to be further studied. As far as eastern Mediterranean is concerned, Mysida and Lophogastrida have received little attention mostly due to difficulties in sampling these particular taxa especially in oligotrophic shelf areas (Koulouri et al. 2013). However, it is expected that several species distributed in other Mediterranean regions will be recorded as elements of the Greek fauna in the future.
