PROSHCHALYKIN & DATHE, 2012: 23.

Material examined: Erzurum: Oltu, Çamlıbel , 22 km WSW of Oltu, 1700 m, 40°28N 41°47E, 23.06.2001, ; 02.07.2001, ; 30.07.2003, , leg. J.G. Rozen, H. Özbek (coll. AMNH) . Muğla: Köyceğiz , 10.06.1987, , leg. P. H. v. Doesburg.

Remarks: H. pectoralis is recorded in Turkey for the first time. The species is well known as a user of vacated galls of the chloropid fly Lipara lucens MEIGEN in reed stems ( Phragmites australis ). It nests in the abandoned galls and is therefore confined to wetlands with stands of reeds. The collecting site in Erzurum is a narrow valley containing pastureland, through which a stream flows, a branch of the river Çoruh, beside which are small Phragmites patches.

In agreement with the general situation for this species, H. pectoralis shows a limited, disjunctive distribution in Turkey. Hitherto, H. pectoralis has been found at four places in Erzurum and Muğla only. It is rarely recorded in Turkey (2 provinces, Figs 16.7 , 17 .IV).

Distribution: Transpalaearctic from the Pyrenees to Japan, but because of its specific ecological requirements only locally recorded. Turkey: Erzurum and Muğla. New to the Turkish fauna.
