Anthidium astilleroi

The type series of A. astilleroi includes 11 females described from Morocco. No males were described. The authors describe A. astilleroi as similar to both ‘ lituratum ’ (= P.nanum ) and ‘ ferrugineum ’ [= Icteranthidium ferrugineum (Fabricius, 1787) ] based on the colour of the metasoma yet different from ‘ ferrugineum ’ in the shape of the scutellum. They conclude that A. astilleroi is more similar to A. lituratum but also mention that there are no two identical specimens in the series but rather a series of ‘modifications’. The type material should thus be carefully examined to determine to which taxon the name should be applied, as well as to verify that the type series does not include multiple taxa. We include this taxon here in the discussion because it was synonymized with P. stigmaticorne by Warncke (1980) but we have not examined the type series.
