Anthidiellum (Anthidiellum) beijingense Portman & Ascher nom. nov.

Anthidiellum (Anthidiellum) borealis Wu 2004: 775 (primary homonym of Anthidiellum boreale (Robertson)) .

Anthidiellum (Anthidiellum) boreale: Niu et al. 2016: 329 .

Etymology: This species is named for the type locality of Beijing.

Comments: The spelling of Anthidiellum borealis Wu, 2004 must be changed to boreale for purposes of gender agreement, as stipulated in Article 31.2 of the International Code of Zoological Nomenclature (ICZN). It is therefore a junior primary homonym of Anthidiellum boreale (Robertson) , and must be replaced, following the provisions of Article 60 of the ICZN. As there are no available and potentially valid synonyms, it must be given a new replacement name.

Distribution: Anthidiellum beijingense is currently known to occur in China ( Wu 2004; Niu et al. 2016).

Non-native species

Eleven species in Minnesota are considered non-native. The honey bee ( Apis mellifera ) is actively managed for and found throughout Minnesota. Andrena wilkella is commonly found throughout much of Minnesota, particularly in disturbed habitats, and can be locally abundant. It is thought to have been introduced into North America through ship ballast ( Giles and Ascher 2006). The earliest records of this species in Minnesota are from specimens collected in 1956 in Houston and Washington Counties. Two species of Anthidium ( Anthidium oblongatum , first detected in 2013, and Anthidium manicatum , first detected in 2008; Portman et al. 2019) are associated with city gardens and have thus far been found exclusively across the Twin Cities metropolitan area, but thus far they do not appear in contemporary surveys outside the metro counties. Similarly, the recently detected Pseudoanthidium nanum has only been documented from one specimen from Minneapolis ( Portman et al. 2019). Hylaeus leptocephalus was first documented in Rock County in 1913 and has been documented sporadically across Minnesota. Two species of non-native Lasioglossum ( Lasioglossum zonulus and Lasioglossum leucozonium ) are found in prairies and grasslands throughout the state and can be locally abundant. Megachile rotundata was first detected in Minnesota in 1951 in Ramsey County. Osmia caerulescens was reported in Mitchell (1962) but there are no specimens in UMSP nor any collected in the projects described above. Megachile sculpturalis was documented by photograph by Heather Holm from Carver County in 2016, but it does not appear to be established as recent surveys have not re-documented this species. Lastly, it is unclear whether Megachile centuncularis is exotic or not ( Giles and Ascher 2006, Zarrillo et al. 2016), so we are not including it in our total count.
