Andrena (Hoplandrena) rosae Panzer, 1801

Andrena (Hoplandrena) schoenitzeri Gusenleitner, 1998 syn. nov.

Remarks. Gusenleitner (1998) described A. schoenitzeri (type photographs available at https://www.zobodat.at/ belege.php) from eastern Turkey and Azerbaijan and diagnosed it against A. clusia and A. mordax due to its dark pubescence. However, this overlooks dark individuals of A. rosae . Structurally, there are no differences between the two taxa, with females displaying the same medially shining propodeal triangle, terga with at most short and scattered hairs, and densely punctate clypeus, with males sharing the same quadrate A3 (slightly shorter than broad, at most one quarter the length of A4), apically truncate S8 (not medially emarginate), and simple genital capsule. Andrena rosae is an extremely widespread species, but shows substantial colour variation across this range for both the terga and pubescence. In the Eastern Palaearctic for example, it shows the presence of white apical tergal hairbands ( ssp. alfkeni Friese, 1914 , e.g. Xu & Tadauchi 2005). In Turkey, the species is absent from the western part of the country (see map in Gusenleitner & Schwarz 2002), but reappears in the east where individuals are almost entirely black, though individuals with very dark red discs of T2 can be found, as is the case for one of the paratypes of A. schoenitzeri . These black individuals can be found from eastern Turkey, through the Caucasus and Iran to some parts of Central Asia where the more typical red form also occurs.

Distribution. Palaearctic, from Iberia to Japan ( Gusenleitner & Schwarz 2002).
