Scientific Name: Bombus johanseni Sladen, 1919
Common Name: Johansen s Bumble Bee
Bombus sylvicola var. johanseni Sladen, 1919: 30g [â™€]
Holoytpe â™€. CANADA, Northwest Territories, Bernard Harbour, 3 July 1916 [3 July 1915], Canadian Arctic Expedition, by F. Johansen [CNC no. 2029].
Bremus silvicoloa johanseni Criddle 1926: 107 [lapsus calami]
Bombus (Pyrobombus) interacti Martinet, Brasero, and Rasmont, 2019: 611 [â™€, â™‚] [synonymy by Sheffield et al. 2020: 65].
Holotype â™‚. USA, Alaska, Toolik field station, 68°37′32.9″N 149°35′48.8″W, 725m, 28 July 2015, by Martinet and Rasmont, on Epilobium angustifolium [Royal Belgian Institute of Natural Sciences].
The type locality of B. johanseni is in northern Nunavut; Northwest Territories was originally indicated in by Sladen (1919), and subsequently by Sarazin (1986), but Nunavut officially separated from the Northwest Territories on 1 April 1999 via the Nunavut Act.
Though the specimen is labelled as a “Lectotype”, designated by H.E. Milliron in 1960, we cannot find any published account of this designation, though it was not required as Sladen (1919: 30g) clearly indicate the “type” as a single queen collected on 3 July 1916 [1915 in Sladen 1919), the only specimen with that collection information.
Though Sladen (1919) originally described and treated his taxon as a variety of B. sylvicola s. str., which was done so by subsequent authors (e.g., Frison 1927a, 1927b; Hurd 1979) we consider this name valid as according to Article, 22.214.171.124 of the ICZN Code (International Commission on Zoological Nomenclature 1999), an infrasubspecific name (i.e., under Article 45.6.4) is considered subspecific from its original publication use if, before 1985, it was either adopted as the valid name of a species or subspecies, which was done so by Lutz and Cockerell (1920) who treated it as a subspecies of B. sylvicola s. str.
The DNA Barcode Index Number (BIN) for this species is BOLD:ABA8452.
