Bombus folsomiand the origin of Philippine bumble bees (Hymenoptera: Apidae)

摘要

AbstractThe type female ofBombus folsomi(Frison) is redescribed and synomymized withB.ephippiatusSay. It is concluded that the putative type locality ofB.folsomi, Mt Kinabalu in Borneo, is in error and that the genus appears to be absent from Borneo. This lends support to the hypothesis that bumble bees immigrated to the Philippines by an unusual northern route through Taiwan. More rigorous testing of this idea will require further cladistic analysis of the genusBombus.
