## Abstract

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.

## Body

## 1. Introduction

Araneae (spiders) is one of the largest orders of Arachnida, and they are found worldwide on all continents except Antarctica. They generally inject venom into other animals, including humans, to protect themselves or hunt their host [1, 2]. Spiders consist of 49937 species, classified into 130 families and 4239 genera [3]. Of these, four genera Loxosceles Heineken and Lowe, 1832 (Sicariidae), Latrodectus Walckenaer, 1805 (Theridiidae), Phoneutria Perty, 1833 (Ctenidae), and Atrax O. Pickard-Cambridge, 1877 (Atracidae), are the most medically important spiders that bite and are dangerous to humans. However, most cases of the spider bite effect are benign, and in some cases, it may lead to serious consequences. In the Asia-Pacific region, several medically important spiders may cause either malignant systemic clinical envenomation syndromes or significant local reactions [4].Recluse spider (Loxosceles spp.) envenomation is one of the most common health problems in Northern America, Mexico, and Brazil. The genus Loxosceles Heineken and Lowe currently consists of 140 species in the world [3]. In Iran, 763 species from 296 genera and 51 families have been reported, and Loxosceles persica Ribera and Zamani, 2017, L. rufescens (Dufour, 1820), L. turanensis Zamani, Mirshamsi, and Marusik, 2021 and L. coheni Zamani, Mirshamsi, and Marusik, 2021 have been introduced before from different parts of Iran [5, 6] (Figure 1).Figure 1

Moreover, latrodectism caused by Latrodectus cinctus bite was reported in southeast Iran [8].Studies show that the only species of recluse spiders occurring in Iran is the Mediterranean recluse spider,Loxosceles rufescens, which has been recorded from Fars, Hormozgan, Razavi Khorasan and Tehran Provinces so far [7]. According to studies conducted in Hormozgan Province, 49 species from 38 genera belonging to 16 families have been identified so far [6].


## 2. Objectives

Despite case reports of spider bites in Hormozgan Province [7] and other neighboring areas [8], so far no comprehensive study on the fauna of spiders has been conducted in Bashagard county. Given the Oriental climate and the occupation of most people in this region (animal farming and agriculture), the possibility of residents’ exposure to spiders will increase. Therefore, conducting such studies on medically important spiders in this tropical and lesser-known region seem completely necessary.


## 3. Materials and Methods

Bashagard county is located in Hormozgan Province, south of Iran (Figure2). The average altitude in this county is 2320 above sea level. This study was conducted from February 2017 to September 2018.Figure 2

Samplings were carried out at least four times in each area (two times in the day and two times in the night), covering up to a radius of 500 meters from the defined locations.Specimens were collected mainly from inside and surroundings of different ecosystems and residential areas, using various methods, including hand collection, pitfall trapping, and aspirator sampling. All collected samples were preserved in 70% ethanol for further studies.The epigyne of the female specimens was separated, cleared, and cleaned with 10% KOH solution. Illustrations were captured using an Olympus SC100 camera attached to an Olympus SZ61 stereomicroscope. All spiders were placed in the Entomological Museum of Shiraz University of Medical Sciences (EMSUMS). Nomenclature and global distribution data are according to the World Spider Catalog (2022), previous Iranian records are according to Zamani et al. (2021), and mentioned as “Iranian provinces” [3, 6].Mr. Alireza Zamani has performed the final confirmation of the morphological identification of all collected species.


## 4. Results

During the sampling period, 391 samples were collected from all defined locations of the county. Of all the collected samples, 127 identifiable specimens were considered for morphological identification. The rest of the samples were unrecognizable because they were juvenile or damaged; they did not have the required morphological characters. 11 species belonging to 9 genera and seven families were identified using valid taxonomic keys (Table1). Immature specimens were identified only at the family level (Table 2).Table 1

The most species richness was observed in Location 11 (Sardasht) with seven collected species. Furthermore, three species were also collected from locations 1 and 13 (Irmish, and Dargazan). Two species were collected in locations 2, 4, 9, and 15. Only one species was caught in other sites. Loxosceles rufescens (Figure 3), as one of the most medically important species, was collected only from the southwest part of the county in Gorichi (Location 14).Figure 3

## 5. Discussion

Based on our results,Plexippus minor Wesołowska and van Harten, 2010, is a new record for the spider fauna of Iran, and had the northernmost locality in the whole known distribution range. Moreover, in this study, we are reporting Eusparassus mesopotamicus Moradmand and Jäger, 2012, and Artema doriae (Thorell, 1881) for the first time from Hormozgan Province.One of the most important species of medical importance,L. rufescens (Dufour, 1820) from the family Sicariidae Keyserling, 1880, has been reported from Tehran province for the first time in Iran by Zamani and Rafinejad [9]. In addition, in Hormozgan province, this species has been reported from Kish Island, Bandar Abbas County, Hormuz Island, and Qeshm Island [10].Several cases of loxoscelism have been reported from different parts of Iran including Hormozgan Province that reflect these arachnids’ importance in public health [7, 11, 12].Recently, latrodectism was reported from the vicinity of Bashagard County (Zahedan, Sistan, and Baluchestan province) [8]. Although we did not catch spiders from this family in this study, the existence of this spider is probable due to its great climatic and geographical similarity with Sistan and Baluchestan province.In a faunistic study on the spiders of Kohgiluyeh and Boyer-Ahmad Province, 49 species belonging to 38 genera and 15 families were reported [13]. Considering that our study only covered one county, identifying 15 species of spiders is not far from expected. Although biodiversity was not high in our study area, identifying medically important species can be essential and alarming for the area’s general public and health policymakers.


## 6. Conclusion

In this study, we increased our knowledge of the geographical distribution of spiders in this lesser-known region. Although most of the specimens caught in this study were spiders with no medical significance,L. rufescens is a species with high medical importance. We report its presence from Bashagard county for the first time. Symptoms of loxoscelism ranges from skin necrosis to death. Therefore, it is suggested high-risk people such as farmers and ranchers should be trained on exposure routes and medical intervention after the bite of this spider. As the studied area (Bashagard county) is one of the areas that are difficult to access and does not have access to good connecting roads to transfer the patient to hospitals. In addition, there is not any specialized hospital near the county, it is crucial that health center staff should be trained on the symptoms of the bite and how to treat it. They should be alert about this species and warn high-risk residents about the potential consequences of this spider, especially where the spider was reported from (Location 14: Gorichi).
