Spiders are the largest order of arachnids with some medically important species. Considering that no comprehensive research has been conducted on the fauna and distribution of Araneae in Bashagard County (Hormozgan Province) so far, the present investigation has been carried out on these essential issues in this deprived tropical region. Fifteen sampling locations were selected based on the extent of each area and considering climatic characteristics. Samplings were carried out at least four times in each region from February 2017 to September 2018, covering up to a radius of 500 meters from the defined locations. Specimens were collected using the hand collection method, pitfall trapping, and aspirator sampling. All collected samples were preserved in 70% ethanol and were identified using valid taxonomic keys. Of all the 390 collected samples, 134 identifiable specimens were considered for morphological identification. 11 species belonging to 10 genera and seven families were identified. Immature specimens were identified only at the family level. Wadicosa fidelis was the most distributed and abundant species in the area, with 13 localities and 84.33% of all identifiable samples. Plexippus minor is a new record for the spider fauna of Iran. Moreover, Loxosceles rufescens, a medically important species, Artema doriae, and Eusparassus mesopotamicus were reported for the first time from Hormozgan province. Despite collecting only one specimen, of L. rufescens, due to the lack of proper medical facilities and transportation systems in the area, health staff must be alert about this medically important species and warn residents about its potential dangers.
