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 ...

On nine species of the genus Bowie (Araneae: Ctenidae) from China and Malaysia

Abstract

Nine species of the genus Bowie Jäger, 2022 are recorded from China and Malaysia, including seven new species described here. Five species are reported from Yunnan, China: Bowie achang Shang, Zhang & Wang, sp. nov. (male, female), B. dai Shang, Zhang & Wang, sp. nov. (male, female), B. lahu Shang, Zhang & Wang, sp. nov. (male), B. nangunhe Yang, Zhang & Wang, sp. nov. (male, female) and B. wa Yang, Zhang & Wang, sp. nov. (male, female). Additionally, B. tujia Shang, Zhang & Wang, sp. nov. (male) is described from Guizhou, China, and B. weiweii Shang, Zhang & Wang, sp. nov. (male, female) from Sabah, Malaysia. The previously unknown sexes of B. lishuqiang Jäger, 2012 (male, from Chongqing, Sichuan and Guangxi of China) and B. mengla Yao & Li, 2022 (female, from Yunnan of China) are described here for the first time. Photos of habitus, copulatory organs and a distribution map for all species are provided.
