Laboratorio de Aracnología Facultad de Ciencias UNAM


Our laboratory studies the diversity and taxonomy of Araneomorphae spiders. The tools we use are species inventories documented online with high resolution images organized as standard views and the descriptions of those new species.

These websites were created to compare undescribed taxa from different inventories. They also have been useful for identification of complicated taxa and the description of new species. With enough time we hope to provide the best online documentation of Mexican araneomorph spiders.

The following books provide a good introduction to the biology of the Order Araneae: Biology of Spiders 3ed (Foelix 2011), Spiders of North America an identification Manual 2ed (Ubick et al. 2017) and Spider Families of the World (Dippenaar-Schoeman & Jocque 2006).

We hope that you find these data useful and thanks for your visit. Please cite this web site as follows:

Biodiversity Inventories UPDATES!

We have 6,819 images for approximately 570 species of Araneomorphae from Mexico. Please visit our spider inventory websites and enjoy!

🕷 The process for inventory online documentation has been automated. The many bugs in the first versions of BIOINV have been fixed in V2.2 and a small web site example included.

🕸   The spider inventory for Los Tuxtlas Biological Station is done. 237 species were collected and documented with 2,514 standard views, the ecological data was also published and the data set is available here.

🔬   We were able to take 200X images with the same equipment, look for the smallest species in Los Tuxtlas inventory.

🖳   Inventory Comparative Search is back.
