International Society of Arachnology

The International Society of Arachnology is the premier international scientific society devoted to arachnology. ISA focuses on the arachnid orders Amblypygi, Araneae, Opiliones, Palpigradi, Pseudoscorpiones, Ricinulei, Schizomida, Scorpiones, and Uropygi, but not Acari, as other societies dedicated to acarology exist. Currently ISA has about 600 members from 66 countries. ISA's goals are to promote the study of Arachnology and communication of arachnological information among researchers via meetings and publications (printed or electronic).
