During the 2005 leg of the MEDITS trawl survey, benthic anthropogenic debris around the Maltese Islands (central Mediterranean) was quantified for the first time, with the aim of studying its abundance and distribution in the area. 357 items were sampled from 3.5 km2 of swept area. Each item was recorded, measured and its planar and surface areas were estimated. Plastic (47%), metal and glass (13% respectively) were the most prevalent types of litter in terms of number. Limestone slabs, sacks and fabric were the items with the highest planar and surface area per item. This suggests that it is also important to consider the size of debris items as well as numerical abundance in assessing impact of litter on benthic organisms. An attempt was made to correlate anthropogenic and environmental variables, including fishing activities and wave parameters, to litter abundance and distribution but no interpretable correlations were found, implying that litter abundance and distribution depends on factors other than those considered.

A sesiid species, Tinthia tineiformis (Esper, 1789), is reported for the first time from the Maltese Islands, central Mediterranean. This new record represents the first species belonging to the subfamily Tinthiinae in Malta. The specimen was identified through morphological and genetic analyses. Observations of the live specimen revealed the use of jumping strategies by this species.

The MARCOS cruise, which took place in the South Central Mediterranean Sea on board the RV ‘Urania’, resulted in the collection of 27 species of Echinodermata from shallow to bathyal depths, many from around Malta (the Fisheries Management Zone). The fauna is represented by common to rare taxa already reported from the Mediterranean with the exception of the amphi-Atlantic ophiuroid Ophiotreta valenciennesi rufescens (Koehler, 1896), recorded from the Mediterranean Basin for the first time. Odontaster mediterraneus (von Marenzeller, 1893) and Luidia sarsi Lutken, 1858 are also first records for the Maltese Islands.

The occurrence of Pachygrapsus maurus and Pachygrapsus transversus is reported from the Maltese Islands for the first time on the basis of one specimen of P. maurus collected in 1990 and numerous recent specimens, and the distribution of the two species is mapped. The controversial presence of P. maurus in Italy is confirmed and two new sites for this species are reported, including the first for the mainland of Italy. The examination of the historical specimen of P. maurus from the Genova area revealed a misidentification of P. transversus; this record could be a result of ship-mediated transport. First notes on the habitat of P. maurus in the central Mediterranean Sea are given. Updated maps of the distribution of P. maurus and P. transversus in the Mediterranean are provided and the zoogeography of these species is revisited.

The heterokont benthic multicellular algae Schizocladia ischiensis E.C. Henry, K. Okuda et H. Kawai (Schizocladiophyceae), Hecatonema terminale (Kützing) Kylin and Striaria attenuata (Greville) Greville (Phaeophyceae) are reported for the first time from the waters around the Maltese islands in the central Mediterranean. They were identified through algal isolation from incubated natural substrata, coupled with DNA barcoding targeting the biomarkers COI and rbcL plus the RuBisCO spacer. For three additional brown algae, Colpomenia sinuosa (Mertens ex Roth) Derbès et Solier, Asperococcus bullosus J.V.Lamouroux and Sphacelaria sp., DNA sequences confirmed previous morphology-based records from Malta. This paper also provides an updated literature-based species list of the marine macroalgae present in Malta.

Critical Literature

The Maltese Islands are situated in the Central Mediterranean basin having a total land area of c. 316 km2. A diverse ant fauna is present in this archipelago, which is increasingly threatened by habitat degradation and invasion of alien species. The myrmecofauna of the archipelago has received considerable attention by researchers since 1893, bringing the total number to 59 species (Gómez 2017, Salata and Borowiec 2018), 11 of which are non-native. Confirmation of some already reported species, e.g. Messor structor (Latreille, 1798), Tapinoma nigerrimum (Nylander, 1856), Tetramorium caespitum (Linnaeus, 1758), is required in the light of recent taxonomic changes. Based on a critical literature review, older unpublished data (1995–1997) by one of us (DM), and newly collected ant material (mainly between 2015 and 2019) we provide an updated list of 70 ant species from the Maltese Islands. The specimens were collected by different techniques (e.g. direct sampling, sifting, MSS-traps, Malaise traps). Two ant species were recorded for the first time in the Maltese Islands and for five species we provide the first verified records. Seven morphospecies with unspecified taxonomic status were also collected and require further studies.
