First record of two genera of Hoverflies (Diptera: Syrphidae)
from East Azerbaijan Province, Iran
Samad KHAGHANINIA, Abbas SHAKERYARI & Rüstem HAYAT
Based on collected specimens of hover flies (Diptera: Syrphidae) from East Azerbaijan province located in the northern west of Iran during 2010-2011, two species and genera, Ferdinandea cuprea SCOPOLI 1763 and Sphegina clunipes FALLÉN 1816, belonging to subfamily Milesiinae were determined as new records for the Iranian insect fauna. The photographs of the specimens are provided.
Key words: Fauna, Diptera, Syrphidae, New records, Hover flies, Iran.
Bei Durchsicht der in den Jahren 2010-2011 gesammelter Schwebfliegen (Diptera:
Syrphidae) aus der Provinz Ost-Aserbaidschan, stellten sich Ferdinandea cuprea SCOPOLI 1763 und Sphegina clunipes FALLÉN 1816, beide der Unterfamile Milesiinae angehörig, als neu für den Iran heraus.
© Entomofauna Ansfelden/Austria; download unter www.zobodat.at Introduction Hoverflies is one of the largest and most diverse families of the order Diptera which include about 200 genera and more than 6.000 described species over the world. These flies are common pollinators which is present wherever flowers are found, being absent only in truly arid areas and the Polar Regions. This group consists of small to medium flies 6-18 mm long which can be distinguished by the special venation of the wing (spurious vein) (KEVAN & BAKER 1983).
The species of the subfamily Milesiinae are the most common and conspicuous which contain about two thirds of hoverflies. Many species, being regular visitors of flowers, are important pollinators of various plants including vegetables, fruit trees (Asteraceae, Brassicaceae, and Rosaceae) and flowering plants (FAEGRI & van der PIJL 1979). In this subfamily humeri is hairy and head naturally sits well forward so that the humeri is clearly visible (MAIBACH et al. 1994).
One of the significant characters of these flies is the ability of them to keep the body motionless in the air for quite a period of time during flight. The adults mainly feed on nectar or pollen for proteins, lipids and vitamins (STUBBS & FALK 2002). Nearly most of Milesiinae members are generally seen around ponds, marshes and wet lands where there is a large amount of decaying vegetation, wood and rotting seaweeds. The larvae contribute to the purification of water by filtering out microorganisms as well as organic products. Some of them feed on plant materials and decaying organic matters (GILBERT 1981).
In the tribe Cheilosini the wide eye rim (zygoma) is not found in other Milesiinae, the rim consisting of a narrow strip bounded by the eye on one side and a groove on the other. In this tribe the face is fairly normal (with a knob) and very hairy species in Cheilosia and Ferdinandea (BEI-BIENKO 1988). In the tribe Chrysogasterini the presence of a concave face, smoothly leading to a projecting mouth margin, is characteristic of the tribe. The genus Sphegina is small, almost glabrous and slender flies. Larvae live in dead wood, in sap runs, in aquatic or subaquatic situations or in decaying vegetable matter (STUBBS & FALK 2002).
Recently the hoverflies fauna of Iran were studied by some taxonomists (DOUSTI 1999;
GOLDASTEH et al. 2002; GOLMOHAMMADI & KHIABAN 2004; GILASIAN 2005; DOUSTI & HAYAT 2006; GHARALI & REEMER 2008, 2010; KHAGHANINIA & BASHIRI 2011;
KHAGHANINIA et al., 2012; KHAGHANINIA and SHAKERYARI 2012; SHAKERYARI et al.,
2012) who shows no records of the Ferdinandea RONDANI 1844 and Sphegina (MEIGEN
1822) genera from Iran.
Material and methods
Studied specimens were collected from wetlands having long reed beds near to wood lands from Isperekhan and Mekidi valleys located in south and northern east of East Azerbaijan province, respectively, using common entomological sweep-net during 2010 and 2011 (Fig. 1). The samples were killed in a killing jar containing potassium cyanide and the voucher specimens were deposited at Insect Museum of Tabriz University. The © Entomofauna Ansfelden/Austria; download unter www.zobodat.at specimens were identified based on valid keys such as STUBBS & FALK (2002) and SPEIGHT (2008). The range and visited flowers of the recorded species are provided mostly from SPEIGHT (2010).

Genus Ferdinandea RONDANI 1844 Diagnostic c h a r a c t e r s : The black thoracic dorsum has grayish longitudinal stripes, rather like Helophilus MEIGEN 1822, but there are stout bristles along the lateral edges. The abdomen is brassy colored or bluish black. The wings have clouded inner cross-veins (SPEIGHT 2008).

Genus Sphegina (MEIGEN 1822) These hoverflies are on the whole larger than Neoascia WILLISTON 1886, with a conspicuously longer narrow waisted in both sexes. The outer cross-veins have rounded angles and lack infuscation. The front and mid femora are always pale with at most a slight incomplete dusky ring. The males have a yellow patch on tergite 3 and sometimes also on tergite 4 (COE 1953). The larvae occur in accumulations of decaying sap under bark in damp woodlands (BEI-BIENKO 1988).
