International Society of Arachnology
The International Society of Arachnology (ISA) is the premier international scientific society devoted to arachnology. ISA focuses on all arachnid orders. Currently ISA has about 500 members from 70 countries. ISA's goals are to promote the study of Arachnology and communication of arachnological information among researchers via meetings and publications.
The ISA organizes the International Congress of Arachnology every three years. The Congress features symposia of current interest and contributed papers.
The society maintains a database of members including contact information and professional interests to facilitate communication among arachnologists.
Please support the society and become a member!

Faces of Arachnology
Catalina Romero Ortiz
My research focuses on pseudoscorpion taxonomy and systematics and on the evolution of sexually selected morphological traits. During my PhD I revised Withiidae male genitalia and compared their evolutionary rates with non-sexual traits. I now apply integrative taxonomy using UCEs to study diversification of multiple morphological structures.
