A key to the studied species along with their diagnostic characters, geographical distribution and supplementary figures are given. Key words: Chloropidae, Meromyza, Iran, Shabestar, New records. Introduction The family Chloropidae, commonly named grass flies, has 204 genera and more than 2500 described species belongs to 4 subfamilies (Siphonellopsinae, Rhodesiellinae, Oscinellinae, Chloropinae) are a fairly large family of Acalyptratae flies (Nartshuk 2012). The frit flies of the genus Meromyza Meigen, 1830 belong to the subfamily Chloropinae which has 95 species in the Holarctic region, 67 of which are identified from Palaearctic and 23 of them are from Nearctic Region and the rest are found in other zoogeographical regions. Larvae of this genus are Bi considered as pests of several species of poaceus plants, including the wheat, rye, and barley (Nartshuk & Fedoseeva 2011a). The main characteristics of these flies are as follow: yellowish and greenish elongated body, except of the subgenus Nippomera Fedoseeva et Nartshuk, 1983 which has a completely black body; the mesonotum with black, brownish or rufous longitudinal Citation as online first paper: Biharean Biologist (on-first): art.151206 stripes; head square with short setae; ocellar triangle with a black ocellar tubercle and black spots; the hind femur is thickened with two rows of black spines ventrally, the hind tibia is curved accordingly; wing veins R2+3 and R4+5 are curved sharply towards its anterior margin in g (Nartshuk et al. 1988, Nartshuk & Fedoseeva 2011a, Nartshuk & Andersson 2013). The presence of a wide phenotypic plasticity in the genus like seasonal as well geographical colorations make pr oo f some difficulties in their identifications (Nartshuk & Fedoseeva 2011a). In the nearest studies, Ozerov (2009) described Meromyza filippovi Ozerov from the European part of Turkey, Nartshuk & Fedoseeva (2011a, b) reviewed the genus Meromyza in the Palaearctic region, Nartshuk (2011- 2012) studied the chloropids of Turkey and described the Ac ha r ce ea pt n ed Bi o pa lo pe gis r- t un til Meromyza turcica Nartshuk. Nartshuk & Andersson (2013) published a comprehensive book entitled “The Frit Flies (Chloropidae, Diptera) of Fennoscandia and Denmark” about this family and, Safonkin et al. (2013) studied the distribution of the genus Meromyza in Vologda Oblast and East Poland. Before this study 19 species of the genus Meromyza had been identified from Iran (Behdad 1982, Rajabi et al. 1997, Nartshuk & Fedoseeva 2011b, Khaghaninia & Gharajedaghi 2013, Khaghaninia et al. 2014). Faunistic study on this genus has not been carried down in Shabestar region so far, therefore this study was conducted in this. Materials and Methods Materials were collected by sweeping the poaceus plants’ heads using entomological net Bi from Shabestar region in East Azerbaijan province- Iran during 2013- 2014. Shabestar region is located in the northern east of East Azerbaijan province with X from 45˚5ʹ to 46˚9ʹ E, Y from 37˚5ʹ to 38˚24ʹ N, and varying in altitude from 1275 m to 3195 m a.s.l. The collected specimens were killed in a potassium cyanide jar. In order to dissection of the male genitalia, the postabdomen was removed and soaked in boiling 10% KOH solution for about 10 minutes. The Citation as online first paper: Biharean Biologist (on-first): art.151206 specimens were kept in 75% ethanol in glass vials. These Collected specimens were stored in both the Insect Collection of Professor Hasan Maleki Milani, Tabriz, Iran (ICHMM) and Czech University of Life Sciences collections (CULS). The species were identified according to in g Nartshuk et al. (1988), Nartshuk & Fedoseeva (2011a), and Nartshuk & Andersson (2013). The distributions of the studied species mostly were provided from Nartshuk & Fedoseeva, (2011b) pr oo f and Nartshuk & Andersson (2013). Results In this study, eight species of the genus Meromyza from the Shabestar region were collected and identified which among them, M. filippovi Ozerov, 2008 and M. ornata Ac ha r ce ea pt n ed Bi o pa lo pe gis r- t un til (Wiedemann, 1817) as well as M. curvinervis Zetterstedt, 1848; M. facialis Fedoseeva, 1962 and M. pluriseta Péterfi, 1961 are newly reported from Iran and the East Azarbayjan province, respectively.

Comment: The spring and summer forms are found from fields near the Orumieh Lake with in g about 1300 m latitude and mostly from Mishov mountainside with about 1700 m altitude, respectively. pr oo f Host: Larvae develop in different cereals: wheat, barley, rye and many wild grasses: Aegelops sp., Elytrigia repens, E. tenerum, Agropyron cristatum, Lolium perenne, Arrhanatherum elatius, Phleum pratense, Hierochloe odorata and Calamagrostis epigeios. Therefore, this species is a pest of cereals (Nartshuk & Andersson 2013).

R. Namaki Khamneh. Host: This species feed on Phleum phleoides and also can feed on cultivated cereals. (Nartshuk in g & Andersson 2013, Safonkin et al. 2013). Distribution: This species is distributed in Europe, Afghanistan and Iran (Khaghaninia & Discussion pr oo f Gharajedaghi 2013). Shabestar region with special situation, between Urmiyeh salty lake in the south and the Mishov mountain in the north, has diverse environments with very rich flora and subsequently insect Ac ha r ce ea pt n ed Bi o pa lo pe gis r- t un til fauna like frit flies. Species of the genus Meromyza are found in forest, open habitats such as grasslands, steppe and less frequently, in floodland meadows, on pastures, on roadsides and in fields (Nartshuk & Fedoseeva 2011b). The results show the species M. nigriventris has a large frequency among the other species which followed by M.saltatrix. The species M. nigriventris, one of the most important pests of cereals is collected more significantly from the wheat and barley fields than grasslands, evidently this species prefer the cereals as host more than the grasslands (Nartshuk & Andersson 2013). As the species of this genus could be serious pests of the cereal thus in order to know the fauna of this genus in the other parts of Iran, further studies are necessary. References: Bi Behdad, E.
