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 ...

Scorpions of the Horn of Africa (Arachnida: Scorpiones). Part XXXIV. Four new species of Neobuthus from Somaliland (Buthidae)

Abstract


New information about taxonomy and distribution of the genus Neobuthus Hirst, 1911 is presented, based on material recently collected in Somaliland. Four new species are described, N. dhobo sp. n., N. opatovae sp. n., N. osoli sp. n., and N. verae sp. n. (Somaliland). An updated distribution map of the genus Neobuthus is provided.
