Cyberdiversity of Araneomorphae from Mexico

These pages provide high resolution images mainly of Araneomorphae spiders to allow species comparisons bewteen faunistic inventories for Mexico. These pages are also intended to: expedite the identification process by sharing them with other arachnologists, to provide evidence of species identification and to collaborate in species descriptions. The main purpose of these pages was Araneomorphae spiders although images of other arachnids groups have been included.

Applying standarized collecting protocols is crucial for inventories comparisons. Over the years the spider comunity have used the same collecting protocol with some minor variations. At its core, it basically consist in using the same unit of collecting effort for direct techniques (1 hour/person), and trace areas (of the size that fits you better) instead of transects. One hectare has been used as the standard plot area. If indirect methods are used, please give explicit measurments for the substrate sampled, for example, volume of siffted leaf litter with an aproximate volume of ground substrate procesed.

Please revise the References provided below for the names and codes for individual techniques such as beating, looking up, etc. Remmber that collecting all spider species in an area is impossible, however this protocol is the best the Arachnological comunity has developed. Please use it and, if you find improvements, share them.

All inventories' data sets can be downloaded at the respective Inventory pages. We use Excel to organize the data and produce the input format for the program Estimates. Special thanks to the developers of this program for making these variety of biodiversity statistics available to us (Colwell 2013, Gotelli and Colwell 2001, etc). For more specific information or other data formats contact the authors of individual inventories.

Please send your comments and species identifications to this email: fap@ciencias.unam.mx

Acknowledgements

We would like to thank all the arachnologist that helped with the identification process and recognition of new species, mentioned in each species page. Also thanks to my dear friend Sylvio Drouin for his help in setting up this website. These images were obtained in my laboratory and with the kind colaboration of Gustavo Hormiga's and Charles Griswold's labs. Special thanks to The George Washington University and The California Academy of Sciences (CAS) for sharing the equipment. Funding was provided by UNAM-DGAPA-PAPIIT projects IN213612 and IN214916, CONACYT-SNI and Facultad de Ciencias UNAM.

Instructions

The objective of these species pages is to distribute information, not specimens, to expedite the recognition of new species or ids for described taxa. Please contact us if: the images do not show the diagnostic features that you require, the images are of low quality or we misidentified a species. We will not take it personal, on the contrary, we will be very thankful to you for finding these and other mistakes.

Our cyberdiversity pages can be searched in three ways: Collection search, Comparative search and by Inventory. Select one of these options in the "Cyberdiversity pages" menu. "Collection search" will present the pages by taxon name. If the selected species is found in more than one inventory, then the specimen data and images of all inventories will appear consecutivelly. "Comparative search" will allow to compare simultaneously images of any two species. "Inventory search" will provide the images and data for the species found on the selected inventory.

In any search mode select a taxon from the Family menu to show the included species names, and to enter the species pages just click on any name. Click in the thumbnails to access the high resolution images that will pop-up on separate resizeable windows. This was done with the purpose of comparing images side by side after organizing them on the desktop.

If you retrived an individual page from Google, the link found under the species name will redirect you this web page. Then you can search using any mode described above.
