Remarks: NOTTON & DATHE (2008) recognized during a revision of the Kirby collection that the previously widely-used name Hylaeus annularis had to be replaced by Hylaeus dilatatus . The type locality of Prosopis annularis elbursa WARNCKE, 1981 (a synonym of H. dilatatus (KIRBY) according to our understanding), is not the Elburs mountains in Iran, but the province Hakkâri (2600–3000 m) in Turkey. Here seven provinces are newly added to the recorded distribution. The species shows a sporadic distribution, recorded from sea level (Muğla) up to a main occurrence at high altitudes (2000–3000 m). Achillea millefolium , Cirsium arvense , Heliotropium europaeum and Onopordum sp. are noted as visited plants. H. dilatatus is collected moderately in Turkey (10 provinces).
