Please click on this link to download the Excel data set for this inventory. It includes the raw data for all analyses published in Álvarez-Padilla et al. 2020 "TUXV_2016_2018.xlsx".
This Spider Inventory of Araneomorphae includes 237 species documented with 2,514 compound images. Our results show a 83% of completeness based on several non-parametric and parametric species richness estimators that vary from 312 to 424.

Locality data and descritpion
Locality data: México, Veracruz, San Andrés Tuxtla, Estación Biológica "Los Tuxtlas". 18° 34' 56.1" N, 95° 4' 32.1" W, 192 m. Plot central coordinates. Tropical Wet forest, Lab. Aracnologia FC-UNAM. Follow this link to a Google Earth view of the one hectare polt.
Los Tuxtlas Tropical Biology Station is found at the northernmost distribution of the lowland tropical rainforest in the Neotropics. It comprises 647 hectares of tropical rainforest embedded in close to 155,123 ha which are part of the Los Tuxtlas Biosphere Reserve. This field station, founded in 1967, belongs to the Institute of Biology of the National Autonomous University of Mexico (UNAM). The main objectives of the field station are research and conservation of the tropical rainforest.
Los Tuxtlas field station has been operating for over 50 years and it is one of a few in the set of field stations in the Nootropic where long-term research has been carried out on biodiversity inventories, as well as studies on plant demography, natural regeneration of the forest, physiological ecology of plants, ecological interactions between plants and animals, primate ecology, avian, amphibian and reptile ecology, and forest fragmentation, among other major research areas. The diversity of invertebrates is immense and only through more inventories we will be able to document and describe all the new species found in the region.
These inventory pages also include seven species of Pseudoscorpiones documented with 70 images. A total of 443 specimens (174 immatures and 269 adults) were collected with Berlese funnels, cryptic searching and pitfall traps. These seven species represent a good estimate for one hectare of leaf litter, however other methods that cover their phoretic hosts are needed.
