Ariamnes is a genus of comb-footed spiders (family Theridiidae) that was first described by Tamerlan Thorell in 1869.[2] Some species have greatly elongated abdomens, making them resemble a twig.

Life style[edit | edit source]

These spiders are mostly free-living, at least as adults, although a number have been found to occur as kleptoparasites on the webs of other spiders, at least facultatively. They are nocturnal. The egg sac is elongated. They are rare and little is known about them in South Africa.[3]

Taxonomy[edit | edit source]

Ariamnes was removed from the synonymy of Argyrodes by Agnarsson in 2004.[4]

Species[edit | edit source]

As of October 2025, this genus includes thirty species and one subspecies, found in Asia, Africa, South America, Oceania, the Caribbean, Costa Rica, and Mexico[1]


In synonymy:

  • A. approximatus O. Pickard-Cambridge, 1894 = Ariamnes attenuatus O. Pickard-Cambridge, 1881
  • A. gracillimus O. Pickard-Cambridge, 1894 = Ariamnes attenuatus O. Pickard-Cambridge, 1881
  • A. pulcher Soares & Camargo, 1948 = Ariamnes attenuatus O. Pickard-Cambridge, 1881
  • A. sinuatus Schenkel, 1953 = Ariamnes attenuatus O. Pickard-Cambridge, 1881
