Arthropods are the representatives of taxon diversity and evolution, and participate in key roles in the ecosystem. However there is a lack of general knowledge about their distribution and abundance. The aim of our study was to determine the diversity of walkers arthropod in the Las Flores gully, San Juan province. Pitfall traps were used to capture, which were planted during the spring-summer seasons. The traps were removed at the end of each month and collected for further analysis. In the laboratory were identified and counted the fish caught. For walkers arthropod diversity index was calculated Simpon (D = 0.411) and Margalef index (l = 4.01). The most abundant group was Hymenoptera with 22 different species were found 6 species of Coleoptera, 2 species of Orthoptera, 7 species of Araneae, 1 species of scorpion, 1 species of the Order Solifugae, 1 species of the order Phasmatodea, order Acariina 3 species and 1 species of springtail order. While the data reported so far are for a single month, the results would indicate a high diversity of arthropods to the place, also representing new records of the same presence and distribution of the species found. The high diversity of species of Hymenoptera can be attributed mainly to extreme weather conditions; high socialization ants play a critical role in ensuring the survival of individuals in the group. Future studies should consider using harvesting techniques that incorporate flying arthropods.
