Prosopis (Nesoprosopis) glacialis giresuna WARNCKE, 1992: 770–771 , . Turkey: Hakkâri.

Hylaeus (Dentigera) giresunus ( WARNCKE, 1992) – comb. et stat. nov.

Remarks: The female of H. giresunus (holotype) differs from H. glacialis by the clypeus almost completely concave throughout its length, while in the latter only the clypeus front edge is transversely impressed. Additionally, in the female the front margin of the clypeus has an arcuate tip. The outline of the head is sub-quadratic ( H. glacialis : trapezoidal) and the genae are thickened (normal in H. glacialis ). The habitus of H. giresunus is much more slender, especially the tergum 1, which is strongly shiny; the sculpture of the propodeum is less pronounced. The males are very similar, also in the terminalia, but the proximal extended apical lobes of sternum 7 may be important. H. giresunus is certainly a geographical parallel to the European H. glacialis , but the female appears to be discrete from it.

H. giresunus is a montane (at 1700–2400 m), sparsely recorded species (3 provinces).

Distribution: Turkey: Hakkâri, Giresun, Erzurum
