This paper provides data on distribution of 9 long-legged fly species (Diptera, Brachycera, Dolichopodidae) belonging to 6 genera from Fars province, southern Iran. Four species, Asyndetus albifrons Loew, 1869, Asyndetus chaetifemoratus Parent, 1925, Medetera media Parent, 1925 and Sciapus adumbratus(Becker, 1902) are newly added to the Iranian insect fauna. In addition, available information for each species and comments on geographical distribution and taxonomy are also included.
Key words: Dolichopodidae; Iran; Fars; new records
Introduction
Iranian entomological fauna is receiving an increasing interest in the last few years, compensating for the long dated lack of knowledge. The family Dolichopodidae (Diptera, Brachycera) is not the exception, with a number of papers published in the last years. Most of these studies have been conducted in northern (e.g. Khaghaninia, Gharajedaghi, & Grichanov, 2014; Kazerani, Khaghaninia, & Grichanov, 2014; Kazerani, Khaghaninia, Talebi, Persson & Pollet, 2017) or central parts (e.g. Ahmadi, Gheibi, Ostovan, Hesami, & Grichanov, 2016; Ahmadi, Gheibi, Ostovan, Hesami, & Grichanov, 2017) of Iran, and so far practically no studies have been conducted in southern parts of the country. The Fars province (coordinates 27°01'-31°51'N, 50°27'-55°45'E) is located in southern Iran (Fig. 1). It is the fourth largest province of the country, covering an area of 122,400 km2. The climate in the province varies across counties. The north and northwest areas experience mild summers and moderately cold winters, whereas the weather is hot and dry in the south and southeast. The central region and the surrounding areas have hot dry summers and relatively rainy mild winters. Information on Dolichopodidae of the Fars Province has not been available before our investigation. The aim of current study was to increase our knowledge regarding Iranian long-legged flies, studying Dolichopodidae from southern Iran.
Material and methods
The specimens were collected by Malaise traps in four different localities of the Fars province (South Iran). Sampling localities are briefly described below and shown in Figures 1 and 2.
Loc. A): IRAN, Fars, Dalin, 52°07'54.7"E, 30°02'15.0"N.
Dalin is a small village in Hamaijan rural district, Sepidan County. Dalin is located in the west of Fars province, having a cold and mountainous climate with green and breezy summers and snowy winters. Diverse rivers favour the cultivation of, for example, apple (Maluspumila Miller), plum tree (Prunusspp.) and walnut (Juglansregia L.) orchards.
Loc. B): IRAN, Fars, Shiraz County, Jannat garden, 52°28'9.147"E, 29°36'52.373"N.
The climate has distinct seasons, and is overall classed as a hot semi-arid climate, though it is only a little short of a hot-summer Mediterranean climate. Shiraz contains a considerable number of gardens. Jannat garden has a large number of fruit trees and ornamental plants including walnut, pomegranate (Punicagranatum L.), pine (Pinusssp.) and cypress trees (Cupressus sempervirens L.).

Loc. C): IRAN, Fars, Dasht-e Arzhan, 51°59'3.439"E, 29°39'39.047"N.
Dasht-e Arzhan is a village in Arzhan rural district, Shiraz County. This village lies in an ecologically important zone that is Arzhan and Parishan protected area. The area is included into the southern Zagros, characterized by rocky ground, predominately formed by Quercusspp., together with Astragalusspp. and herbaceous plants.
Loc. D): IRAN, Fars, Larestan, 54°26'1.36"E, 27°31'55.4"N.
Larestan is located in the south of Fars province and has a very hot and desert climate, with hot and dry plains, water shortages and many salt domes. The vegetation includes eucalyptus (Eucalyptus spp.), acacia (Acacia spp.), jujube (Ziziphusspp.) and olive (Oleaspp.). The pastures are mostly covered with milk vetch (Astragalusspp.).
The general species distribution is given after Negrobov, Selivanova, Maslova, & Chursina (2013) and Grichanov (2017, 2018). Type localities are provided, and country lists (in zoogeographical regions) are arranged alphabetically. Photos of some species newly recorded from Iran and habitat photos are provided. The specimens in ethanol have been studied with a ®Zeiss Discovery V-12 stereomicroscope and ®AxioCam MRc5 camera attachment. They will be deposited in collections of the Zoological Museum of Moscow State University, Moscow, Russia (ZMUM), the Zoological Institute of the Russian Academy of Sciences, St. Petersburg (ZIN) and the Department of Entomology, Jahrom Branch, Islamic Azad University, Jahrom, Iran.

Discussion
As a result of 2018 survey conducted in Fars Province, a new material of Dolichopodidae was collected and identified, belonging to 6 genera and 9 (including 4 unnamed) species listed above. The present research gives new records from the southern Iran, including Asyndetus albifrons, A. chaetffemoratus, Medeteramedia and Sciapus adumbratus found for the first time in Iran. In this small collection, we found two undescribed species and four species newly recorded for Iran. Such a large proportion of new species and new records indicates that the Iranian Dolichopodidae fauna is largely unknown and needs more extensive investigation. As a result of our study, the number of reported dolichopodid species from Iran includes now about 155 species. Grichanov, Ahmadi, & Kosterin (2017) suggested that the total number of Iranian species can reach to 400-500 species.
