Andrena (Melandrena) metallescens Cockerell, 1906

Andrena (Melandrena) metallica Radoszkowski, 1876 nec. Fabricius

Andrena (Melandrena) metallescens Cockerell, 1906 nom. nov. for A. metallica

Material examined: CAUCASUS: Caucasus, 1♀, NHMUK (lectotype, by present designation); RUSSIA: Sarepta [Volgograd], 1893, 1♀, leg. Becker, OÖLM .

Remarks. Searches in the NHMUK collection unexpectedly uncovered a specimen of Andrena metallescens ( Figures 33A–D ) which is a replacement name for A. metallica Radoszkowski, 1876 (nec. Fabricius). The type depository for A. metallica is unknown ( Gusenleitner & Schwarz 2002; Osytshnjuk et al. 2008), as much of Radoszkowski’s collection has been dispersed between different museums and the location of type material is not always clear (e.g. Wood 2021a; Wood & Monfared 2022). Cockerell (1906: 166) gave no additional details as to whether or not he had examined material, and therefore it is not clear if he moved the specimen to London or it was moved by someone else. There is no accession number bearing the year that the specimen was integrated into the NHMUK collection, as is typically found on specimens (e.g. Figures 19A , 31A , 32A ). The specimen itself is clearly part of Radoszkowski’s original syntypic series as it bears ( Figure 33A ) the same printed “Cauca-sus” label as for A. assimilis Radoszkowski, 1876 (see Wood & Monfared 2022) and a golden disc of the sort that Radoszkowski typically used to demark his type specimens (see Rosa et al. 2015). The specimen also bears a label with Radoszkowski’s handwriting with the name Andrena metallica . The specimen conforms to Radoszkowski’s description and subsequent use by other authors (e.g. Osytshnjuk et al. 2008), and therefore it is hereby designated as a lectotype.

Distribution: Caucasus, southern part of European Russia, Kazakhstan ( Osytshnjuk et al. 2008; Proshchalykin et al. 2017).
