FIRST RESULTS ON THE DIVERSITY AND DISTRIBUTION OF SPIDERS (ARTHROPODA: ARANEAE) IN THE DEPARTMENT AMBATO, CATAMARCAMorales FL, Barrios Montivero AE, Salas LBBiodiversity Center. Faculty of Exact and Natural Sciences UNCA. E-mail: frankomorales017@gmail.comSpiders are very diverse and abundant chelicerate arthropods. They occupy different ecosystems and they play an important role as controllers of insect populations. Few species in Argentina, can cause accidents to man. The arachnofauna of the province of Catamarca is still little known. The objectives of this research were: know the diversity and distribution of spiders in four locations in the Ambato department, Catamarca province and list the species of sanitary importance. The biological material was collected in La Puerta, Las Juntas, Los Varela, and El Rodeo, in the Ambato department. In each locality, an environment corresponding to the Chaco Serrano ecoregion was selected, in which two transects were plotted with north-south orientation; East West, 50m long × 2m wide, on which 10 pitfall traps were placed, with ethylene glycol solution (1:9). The traps remained active for 28 days, renewed every seven days. The collected organisms were determined up to the family taxonand and genus for spiders of sanitary importance. Morotypes were recognized in each family. 630 individuals from 33 families were collected. More abundant were: Lycosidae (16.03%), Salticidae (13.97%), Thomisidae (12.22 %), Araneidae (11.11%), and Lyniphidae (6.83%). The most diverse families were: Salticidae (12 morfotypes), Araneidae (8 morfotypes), Theridiidae (5 morfotypes), and Lycosidae (5 morfotypes). The genera of sanitary importance were Latrodectus sp. and Loxosceles sp. The data obtained is the first for the Ambato department, thus contributing to the knowledge of the rich spider fauna of Catamarca.
