Pseudoanthidium gregoriense

Pseudoanthidium gregoriense was described by Nobile (1990) as an island endemic from Sicily. Originally described as a subspecies of P. alpinum, Nobile later raised P. gregoriense to species status (1995). As mentioned above for Stelis leucostoma, Nobile (1995) draws parallels between P. gregoriense, P. leucostoma and P. lituratum . We examined four specimens of this taxon identified by Nobile (including one of his paratypes) and a photograph of the holotype, plus two other female specimens from Sicily. These specimens agree with our concept of P. stigmaticorne .
