A comparison of adhesive performance among six cursorial spider species

  A comparison of adhesive performance among six cursorial spider species Abstract The ability to adhere to surfaces is particularly relevant for cursorial predatory arthropods like hunting spiders, which often traverse relatively complex environments characterized by large variation in substrate properties. Here, we evaluated the adhesive performance of six hunting spider species that are common in eastern temperate North America and lack specialized tarsi for climbing smooth or inclined surfaces [Lycosidae: Pardosa lapidicina Emerton, 1885 and Rabidosa rabida (Walckenaer, 1837); Oxyopidae: Oxyopes salticus Hentz, 1845; Pisauridae: Pisaurina mira (Walckenaer, 1837); Dolomedidae: Dolomedes triton (Walckenaer, 1837), and Dolomedes scriptus Hentz, 1845]. We tested adhesion performance as shear load resistance (g) on a glass plate, and as the angle of failure (°) when the plate was gradually inclined relative to horizontal. Average angle of failure and shear resistance differed among ...

New records of spiders (Arachnida: Araneae) from Azerbaijan, including the first record of Nephilidae from the Western Palaearctic

Abstract
New faunistic data on spiders of Azerbaijan are presented. Thirteen species are recorded from this country for the first time: Araniella villanii Zamani, Marusik & Šestáková, 2020 (Araneidae), Cesonia aspida Chatzaki, 2002, Civizelotes solstitialis (Levy, 1998), Cryptodrassus hungaricus (Balogh, 1935), Gnaphosa cumensis Ponomarev, 1981, G. ukrainica Ovtsharenko, Platnick & Song, 1992, Micaria atropatene Zamani & Marusik, 2021, Trichothyse senilis (O. Pickard-Cambridge, 1872), Turkozelotes attavirus Chatzaki, 2019 (all Gnaphosidae),Trichonephila clavata (L. Koch, 1878) (Nephilidae), Neottiura uncinata (Lucas, 1846), Paidiscura pallens (Blackwall, 1834)(both Theridiidae), and Xysticus edax (O. Pickard-Cambridge,1872) (Thomisidae); the genera Cesonia Simon, 1893 and Trichonephila Dahl, 1911 are newly recorded from the Caucasus. The record of T. clavata represents the first documented introduction of this family in the Western Palaearctic.
