The Scientific Committee for the Italian Fauna is managing the new checklist of the animal species of Italy. The previous checklist was published in 1993-1995 and included both protozoans and Metazoa (more than 57,000 species); the new project, which includes only Metazoa, started in 2020 and is aimed at updating the former checklist (with more than 60,000 expected species) by on-line datasets and data papers. The new checklist includes marine species recorded in the Italian seas, divided into nine marine sectors, within the Italian Economic Exclusive Zone, and terrestrial and freshwater species recorded in administrative regions, as well as in the three macro-regions (northern continental, southern peninsular and insular - Sicily and Sardinia - macro-regions). Records from geopolitical units biogeographically related to Italy (i.e., Canton Ticino, CH; Corsica, F; San Marino Republic and Vatican City) are also included. Over 180 Italian and foreign taxonomists have so far participated to the first phase of this new project, providing datasets for taxa at different hierarchical level, from phyla to subfamilies and tribes. The list is intended to be a fundamental instrument not only for the faunistic knowledge of Italy, but also for biodiversity conservation strategies in the country and in the European Union. The new Checklist of the Italian fauna will be available from the LifeWatch Italy platform, and it will be progressively updated. Furthermore, data papers for taxa at different hierarchical level could be published with continuity in a special section of the journal Biogeographia – The Journal of Integrative Biogeography .

The introduction of species outside their native range contributes to the loss of biodiversity, alters the structure and functioning of ecosystems, and damages economy and human health. Insects are one of the taxa with the highest frequency of introduction due to their high diversity, biological properties, and close association with human activities. Here, the allodiversity of Italian entomofauna was analyzed, with a focus on Tuscany (Central Italy). A list of alien insects in Tuscany is included. The status of the alien entomofauna in Italy was updated. The number of alien insects amounts to 122 in Tuscany and 923 in Italy. An introduction rate of 98 species per decade was estimated in Italy. In Tuscany, alien insects belong to 10 orders, mostly Coleoptera (38%), Hemiptera (Sternorrhyncha and Auchenorrhyncha) (23%), and Hymenoptera (13%). They have been most often introduced through vegetable items (ornamental plants or crops). Most species come from the Nearctic region (26%) and are both phytophagous (63%) and amphigonic (80%). Differences and similarities in introduction patterns and in insect abundances across orders among regional, national, and European scales, also considering worldwide abundances, are discussed. Finally, a paucity of information regarding the negative impacts of many species, except for economic pests, phytosanitary threats, and vectors of disease, is underlined. A deeper understanding of the alien insects' ecological impact might help designate policies aimed at preventing further introductions and control the invasive populations of already established species.

The Biodiversity Heritage Library works collaboratively to make biodiversity literature openly available to the world as part of a global biodiversity community.

Published and unpublished data on the centipedes of Corsica (France) is summarised and critically reviewed in this paper. Thirty-three species are listed and discussed (1 Scutigeromorpha, 11 Lithobiomorpha, 4 Scolopendromorpha, 17 Geophilomorpha), one of which is new to the island: Henia (Pseudochaetechelyne) brevis (Silvestri, 1896). General geographical distribution, chorotype, exact localities and ecological notes (altitudinal range, habitats) are given for each species. Eight species are Corsican endemics. Taxonomic remarks are given for some species. General notes on the composition of the centipede fauna of Corsica and its zoogeographic affinities as well as remarks on the ecology of the species and their assemblages are also included.
