Bombus gelidus, (CRESSON, 1878), 2019

BOMBUS LAPPONICUS SUBSP. SYLVICOLA F. View in CoL GELIDUS ( CRESSON, 1878) COMB. NOV.

Holotype: One queen pinned ( Fig. 7). Labels: (1) red, printed with ‘ HoloTYPE 2638’; (2) white, written with ‘aleutian Islds Dau’; (3) red, printed with ‘HOLOTYPE’; and (4) white, printed with ‘Rasmont & Martinet 2018, Bombus (Pyrobombus) lapponicus sylvicola f. gelidus Cresson, 1878 ’. The type specimen is conserved in the Academy of Natural Sciences in Philadelphia (PA, USA).

Bombus gelidus appears as a very dark form of B. lapponicus sylvicola and should be considered as a form of that subspecies.

Further material: In the Smithsonian National Museum of Natural History, Massachusetts Agricultural College and United States National Museum, there are one queen, 14 workers and one male labelled ‘Cotype’ by Franklin (1912). All these specimens should not be part of the typical series and have been labelled erroneously. These specimens were collected later and in other areas than the only holotype described by Cresson (1878). After examination, we consider that these specimens have the typical colour form of B. lapponicus subsp. sylvicola .
