Catalogue of the spiders (Arachnida Araneae) of Sardinia

This catalogue summarizes and critically reviews araneological knowledge about Sardinian fauna. 140 publications from 1868 to 2012 were considered and about 4800 specimens belonging to 254 species were directly examined. The list report 495 species belonging to 229 genera divided into 43 families. For each species, literature, chorotype, regional distribution, and, where possible, habitats are indicated. Among the listed species Philodromus bosmansi Muster et Thaler, 2004 (Philodromidae) is new for Europe and the family of Prodidomidae with the species Zimirina brevipes P?rez et Blasco, 1986 is new for Italy. Also Setaphis parvula (Lucas, 1846) (Gnaphosidae), Centromerus succinus (Simon, 1884) and Hybocoptus corrugis (O. P.-Cambridge, 1875) (Linyphiidae) are new records for the Italian fauna and further 37 species are new for Sardinia. The genitalia of Phrurolithus corsicus (Simon, 1878), Zimirina brevipes, Drassodes luteomicans (Simon, 1878) and Zelotes dentatidens Simon, 1914 are illustrated

Media framing of spiders may exacerbate arachnophobic sentiments

1. Spiders are able to arouse strong emotional reactions in humans. While spider bites are statistically rare events, our perception is skewed towards the potential harm spiders can cause to humans. Nevertheless, there is still limited understanding of the role of the media in spreading (mis)information about them thereby promoting this distorted perception of risk. 2. We examined the human dimension of spiders through the lens of traditional media, by analysing spider-related news published online in Italian newspapers between 2010 and 2020 (n = 314). We assessed the accuracy, circulation and sensationalistic content of each article, and assessed how each of these features drove news' share on social media. 3. We observed a recent, exponential increase in the frequency of the news, particularly those focused on medically important spiders-the Mediterranean black widow Latrodectus tredecimguttatus and the Mediterranean recluse Loxosceles rufescens. The news quality was generally poor: 70% contained different types of error, 32% were sensationalistic, and in virtually none was an expert consulted. 4. The risk scenario depicted by the media reports was unnecessarily alarmist, especially with regard to L. rufescens. A conservative estimate would suggest that less than 10% of the bites reported in the media reports analysed here were delivered by the species described in the report. Moreover, two out of three casualties associated with a bite of the Mediterranean recluse were fake news, while the third was unverifiable. 5. Overstated news referring to spider bites was shared significantly more on social media, thus contributing to frame a distorted perception of the risk. This is important given that these negative sentiments may ultimately lead to lowering public tolerance towards spiders and reducing conservation efforts towards them. We discuss open questions and avenues for future research concerning the media coverage of widely feared animals, that will help bridge knowledge gaps regarding the role of traditional and social media in framing our perception of the natural world.Peer reviewe
