Welcome
Our laboratory documents the species diversity of Araneomorphae spiders from Mexico. The objective is to provide the best online documentation of their morphology to help other areas of biological research. We have approximately 1,000 species collected in various diversity inventories documented with 11,597 images.
Enter the Morphological Database and use the new relational fields search engine. The Araneomorphae from Estación de Biología Chamela IB-UNAM are also included.
Are you new to spider taxonomy?
The following resources provide a good introduction to the biology and diversity of Araneae.
The World Spider Catalog, the most relevant resource for taxonomy and diversity.
Biology of Spiders, 4th ed. (Foelix 2025).
Spiders of the World: A Natural History (Platnick, Hormiga et al. 2020).
Spiders of North America: An Identification Manual, 1st or 2nd edition (Ubick et al. 2005, 2017).
We hope that you find these data useful, and thank you for your visit.
