The AFRICAN ARACHNOLOGICAL SOCIETY (AFRAS) is a scientific society devoted to the study of spiders, scorpions and other arachnids in Africa. It was initiated in 1986 in Pretoria and was first called "The Research Group for the Study of African Arachnida". At the 5th African Arachnological Colloquium (November 1996), the name was changed to the African Arachnological Society.
The purpose of the American Arachnological Society is to further the study of Arachnids, foster closer cooperation and understanding between amateur and professional arachnologists, and to publish the Journal of Arachnology.
The Australasian Arachnological Society aims to promote interest in the ecology, behaviour and taxonomy of arachnids in the Austalasian region, loosely defined as Australia, New Zealand, South-east Asia, Oceania and the Pacific Islands.
