Bibliographic checklist of the Algerian spider fauna (Araneae)

Abstract

The present checklist of the spiders (Araneae) of Algeria is based on literature items published from 1846 to 2022. Altogether 876 species belonging to 51 families are listed. Taxonomic references are mentioned for each species, with indication of synonymous usage or taxa changes. Information about species distribution in the Algerian provinces is also provided, revealing significant disparities in knowledge about each province. Linyphiids present the highest number of known species (155) and the highest endemic richness (54 species). Eight families are represented by a single species. 227 species are known exclusively from Algeria. Moreover, a comparison was executed between the results reported in Algeria and those reported in the neighboring countries (Tunisia, Morocco, and Libya).

Ground spiders (Chelicerata, Araneae) of an urban green space: intensive sampling in a protected area of Rome (Italy) reveals a high diversity and new records to the Italian territory

“… Palliduphantes arenicola (2♀, 3♂) ( Linyphiidae ) is a species associated with open grasslands and dry meadows, previously reported from France and Switzerland ( Denis 1964 , Pozzi and Hänggi 1998 ). Furthermore, we found some interesting and rare species of ground spiders, such as: Zangherella algerica (1♀), already known from central Italy and possibly with a distribution in the Mediterranean wider than previously assumed ( Brignoli 1981 ); Silhouettella loricatula (2♀, 2♂), a small oonopid found mostly in southern Europe in litter and under stones ( Roewer 1942 , Blick et al 2016 ); Orchestina longipes (5♀, 1♂), a rare litter species known only from a few localities in Latium, Tuscany and Veneto ( Brignoli 1967a , Ballarin and Petri 2021 ), in Corsica ( Déjean 2024 ) and Portugal ( Wunderlich 2023 ); Argenna subnigra (11♂), which, up to now, was only recorded in northern Italy ( Pantini and Isaia 2019 ); Micaria pallipes (1♀), a rare ant-mimicking Gnaphosidae with a Turano-Mediterranean distribution ( Tuneva 2007 , Branco et al 2019 , Pantini and Isaia 2019 , Benhacene et al 2023 , Danışman et al 2024 ); Palliduphantes byzantinus (5♂), mostly known from east Europe ( Brignoli 1979c , Blagoev et al 2018 , Danışman et al 2024 ) and recorded for Italy only from southern areas ( Ijland and Van Helsdingen 2016 ); Scutpelecopsis krausi (4♀, 1♂), only found in the Balkans ( Schröder et al 2010 , Blagoev et al 2018 , Blick 2018 ) and in north Italy ( Hansen 1995 ); Euryopis dentigera (1♀), a small and rare Theridiidae only known from a few localities in Europe ( …”
