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 ...

A new species of the genus Sarax Simon, 1892 (Amblypygi, Charinidae) from China

Abstract

A new species of the whip spider genus Sarax Simon, 1892 collected from Guangdong Province, China is diagnosed and described based on morphological characters: Sarax quinquespinus sp. nov. (♂♀). With this third Sarax species recorded in China, the geographical gap in its distribution between Yunnan to Fujian is filled. In addition, a distribution map and the photos of living male and female, copulatory organs and other structures are provided.
