Fig. 4

Examined material. IRAN, Tehran province: 1 ♂, Kuhhaye Tochal, 35°53′N 51°25′E, 2000–3000 m, Reshtehye Kuhhaye Alborz ( Elburz Mountains Central ), 29–30.vi.1973, Exp. Nat. Mus . Praha [ NMPC].

Remarks. Neoascia annexa can be distinguished from other Neoascia species by the following combination of characters: metapleuron closed, with a complete bridge behind hind coxae; protarsomeres 4–5 yellow; wing without transverse brownish stripe along veins M1 and dm–cu; abdominal tergite 2 with a pair of yellowish-orange maculae mediolaterally; tergite 3 with a wide transverse yellowish-orange stripe that evenly reaches the lateral margin; tergite 4 without yellow maculae laterally; abdominal sternite 8 (pregenital segment) in male with blackish pile; hypandrium wide in lateral view (narrow in N. inexpectata Hauser, 1998 ); surstylus without distinct extension anteriorly. Although the yellow pattern on tergite 2 differs from that represented in Barkemeyer & Claussen (1986: figure 6), the male genitalia components match exactly those illustrated in Barkemeyer & Claussen (1986: figure 8) and in Claussen & Hayat (1997: figure 7). This species was collected on the southern slopes of central regions of Elburz Mountains. It is widely distributed in Europe eastwards to Russia and Transcaucasia ( Krpač et al. 2001; Sarıbıyık 2014).
