A faunistic spider list of the ANP Medanos de Samalayuca is provided with a total of 77 species, 51 genera and 21 families. The most diverse families are Salticidae, Thomisidae, Gnaphosidae and Philodromidae. We include information of thirteen new spider records; five are for Mexico and eight for Chihuahua State. Sixteen families, 27 genera and 31 species are reported for the macrophile desert shrub and 15 families, 28 genera and 37 species for the sandy desert vegetation. Complementarity between both types of vegetation was 84%. Thirteen families and 43 species and 11 families and 31 species were captured in vegetation and soil strata, respectively with a complementarity of 95%. Both strata shared three species.
