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 ...

SPIDERS (ARACHNIDA, ARANEAE) FROM NORTHERN GREECE

Abstract
During the spring of 2019, 187 spider species were collected and identified from the north of Greece, in the regional units of Chalkidiki, Serres and Thessaloniki of the administrative region of Central Macedonia. A list of collected species is given. Siwa dufouri (Simon, 1874), Improphantes turok Tanasevitch, 2011, Phrurolithus nigrinus (Simon, 1878), Aelurillus m-nigrum Kulczyński, 1891, Euryopis dentigera Simon, 1880 and Tetragnatha intermedia Kulczyński, 1891 are reported as new for Greece. Some species could not be identified so far: Amaurobius sp., Pritha sp. and Zodarion sp. The female of Pelecopsis pavida (O. Pickard-Cambridge, 1872) is described for the first time.
