A new species of soldier flies (Diptera: Stratiomyidae), Adoxomyia begreliensis sp. nov., based on a male and a female from the Gevne Valley in Turkey is described. The new species characterized by bicolored legs and the species-specific male terminalia is illustrated and compared with related species. Adoxomyia palaestinensis Lindner, 1937 is recorded from Turkey for the first time. An identification key to all East-Mediterranean species of Adoxomyia has been constructed and is presented.
The family Stratiomyidae belongs to the brachycerous Diptera and comprises more than 2600 world-wide species within 375 genera (Woodley 2001). The genus Adoxomyia belongs to the subfamily Clitellarinae and contains about 35 world-wide species according to Woodley's catalog. Hauser (2002) added one new species, A. socotrae, from Socotra Island, Yemen in the Afrotropical Region. Nartshuk (2003) described a new species A. transcaucasica from Azerbaijan and Armenia, and also confirmed that the Palaearctic A. portschinskii is a mere synonym of A. dahlii. In the Palaearctic Region Adoxomyia is represented by 15 species found mainly in south-eastern Europe, Transcaucasus, Near East, Central Asia and China (Rozkošný 1983; Rozkošný & Nartshuk 1988; Nartshuk 2004; Üstüner & Hasbenli 2011).
The adults of Adoxomyia are medium sized dark flies covered mostly with silverish or golden hairs. The antenna is elongated, the antennal flagellum consists of 8 flagellomeres including a more or less thickened last flagellomere (stylus) (Lindner & Freidberg 1978; Rozkošný 1983).
The Adoxomyia fauna of Turkey has been insufficiently studied, and only the following 4 species have been recorded from Turkey (Üstüner & Hasbenli 2011): Adoxomyia aureovittata (Bigot, 1879), A. cinerascens (Loew, 1873), A. obscuripennis (Loew, 1873) and A. sarudnyi (Pleske, 1903). During our investigations of the Turkish Stratiomyidae in Begreli Village (Gevne Valley), Konya-Hadim Province of southern Turkey, I discovered 2 species that represent interesting additions to the Adoxomyia fauna of Turkey. One of them is a new species distinctly differing from A. palaestinensis Lindner, 1937, A. sarudnyi (Pleske, 1903) and A. cinerascens (Loew, 1873). The other species, A. palaestinensis, is recorded in Turkey for the first time.

KEY TO THE EAST MEDITERRANEAN SPECIES OF ADOXOMYIA
The following key (based partly on Lindner 1937) is completed by the inclusion of the new species,. The male of A. hermonensis and the female of A. palaestinensis are unknown.
1. Legs completely black 2
— Legs bicolored or mainly yellow.
2. Antenna entirely black 3
— At least basal half of antennal flagellum red A. ruficornis (Loew, 1873)
3. Scutellar spines short, slender and bare, basal 3–4 flagellomeres in female unusually broad 4
— Scutellar spines longer, thickened and haired, basal 3–4 flagellomeres not as broad A. obscuripennis (Loew, 1873)
4. Female eyes black haired, postocular band wider than scape is long; male unknown A. hermonensis Lindner, 1975
— Female eyes white haired, postocular band as wide as scape is long A. transcaucasica Nartshuk, 2003
5. Legs entirely yellow A. sarudnyi (Pleske, 1903) ♂
— Legs bicolored, at least femora black 6
6. Antenna black 7
— Antenna partly brownish orange 8
7. Body coarse and plump, abdomen with golden yellow hair patches A. aureovittata (Bigot, 1879)
— Body slim and delicate, abdomen with silverish white hair patches A. palaestinensis Lindner, 1937
8. Scutellar spines black, third segment of antenna dark brown to black A. dahlii (Meigen, 1830)
— Scutellar spines yellow, third segment of antenna orange 9
9. Antenna 1.5 times as long as head, male flagellum cylindrical, female first three flagellomeres twice as broad as scape is long Adoxomyia begreliensis sp. nov.
— Antenna about as long as head, male and female flagellum distinctly swollen in middle A. cinerascens (Loew, 1873)
DISCUSSION
Adoxomyia begreliensis is a slender species like A. palaestinensis and A. sarudnyi, while A. obscuripennis, A. dahlii, and A. cinerascens are distinctly stouter. The terminal segment of the antenna of A. begreliensis is relatively thicker than those of A. obscuripennis and A. dahlii. The male of A. begreliensis resembles the male of A. palaestinensis. The main differences in diagnostic features of Adoxomyia begreliensis sp. nov. and A. palaestinensis are summarized in Table 1. A. begreliensis differs from A. sarudnyi by having much darker legs and from A. obscuripennis and A. dahlii by having a much thinner flagellum.

Adoxomyia palaestinensis is recorded for the fauna of Turkey for the first time, and this is the first record outside the borders of Israel.
