New records of Plagyrona Gittenberger, 1977 (Gastropoda: Eupulmonata: Valloniidae) from Europe and problems about specific determination

The genus Plagyrona Gittenberger, 1977, includes only two small species of terrestrial snail: Plagyrona angusta Holyoak and Holyoak, 2012, and Plagyrona placida (Shuttleworth, 1852). While P. angusta is known only from Portugal, P. placida has a vast but fragmented distribution: it is known from some of the Macaronesian islands (Madeira and the Canary Archipelago) and some European countries: Portugal, France (in Corsica only), Italy (including Sardinia and the Tuscan Archipelago), Albania, Greece (in the Ionian Islands only) and North Africa (Algeria). New research has led to redefine the distribution range of P. angusta, identifying new populations in Spain (Balearic Islands), continental France (Var department), southern Italy (Campania), Sardinia and Greece (Kerkyra Island) and to discover new sites of P. placida on Pantelleria island and of Plagyrona spp. in Zannone island and southern Italy. The specific determination of these and others populations by examination of recent literature from Sardinia, Campania and Calabria, was carried out on a morphometric basis, but, for some populations, the variability of the diagnostic characters and the limited number of available specimens, do not allow a precise assignment. On the other hand, the existence of two distinct species is not evident at all, at least in the Mediterranean countries.


Records of Ethiopian and Eritrean mammals in Italian literature and museums, with some taxonomic notes

Published and unpublished data on Ethiopian and Eritrean mammals, mainly deriving from Italian sources, including some natural history museums, in the present contribution are intended as an amendment to the landmark Catalogue of Ethiopian and Eritrean mammals produced by Derek Yalden and collaborators between 1974 and 1996. Additionally, a few taxonomic notes including the proposal of two new subspecific names are included. The paper highlights the importance of historical data for a number of scientific applications, such as taxonomy, conservation biology, and restoration ecology. Two ‘cryptozoological’ records are also included.


Data Papers

A data set on the distribution of Rotifera in Antarctica

We present a data set on Antarctic biodiversity for the phylum Rotifera, making it publicly available through the Antarctic Biodiversity Information facility. We provide taxonomic information, geographic distribution, location, and habitat for each record. The data set gathers all the published literature about rotifers found and identified across the Continental, Maritime, and Subantarctic biogeographic regions of Antarctica. A total of 1455 records of rotifers in Antarctica found from 1907 to 2018 is reported, with information on taxonomic hierarchies, updated nomenclature, geographic information, geographic coordinates, and type of habitat. The aim is to provide a georeferenced data set on Antarctic rotifers as a baseline for further studies, to improve our knowledge on what has been considered one of the most diverse and successful groups of animals living in Antarctica.
