This study presents a taxonomic review of the Argentinean species of Bombus. Keys to identify female and male specimens at the species level [including the Palearctic species, Bombus (Megabombus) ruderatus] are given. Three subgenera are recognized: Fervidobombus, the most diversified, with six different species; Coccineobombus and Robustobombus each with one species. For each taxon, queen, worker and male descriptions are given, as well as the following information: morphological variation, comparative comments and geographic distribution. Also, for each taxon SEM photographs of male genitalia and drawings of female sting capsule are provided.

As pollination is a critical process in both humanmanaged and natural terrestrial ecosystems, pollinators provide essential services to both nature and humans. Pollination is mainly due to the action of different insects, such as the bumblebee and the honeybee. These important ecological and economic roles have led to widespread concern over the recent decline in pollinator populations that has been detected in many regions of the world. While this decline has been attributed in some cases to changes in the use of agricultural land, the effects of parasites could play a significant role in the reduction of these populations. For the first time, we describe here the presence of Nosema ceranae, an emerging honeybee pathogen, in three species of Argentine native bumblebees. A total of 455 bumblebees belonging to six species of genus Bombus were examined. PCR results showed that three of the species are positive to N. ceranae (Bombus atratus, Bombus morio and Bombus bellicosus). We discuss the appearance of this pathogen in the context of the population decline of this pollinators.

A total of 382 bumblebee specimens were examined: Bombus atratus (n = 310), Bombus morio (n = 42), Bombus bellicosus (n = 16), Bombus opifex (n = 8), and Bombus tucumanus (n = 6). Prevalence, abundance, and intensity of mite infestation for each Bombus species and for each caste were recorded. The different mite species infesting bumblebee specimens were: Kuzinia laevis (Dujardin), Kuzinia americana (Delfinado and Baker), Scutacarus acarorum (Goeze), Pneumolaelaps longanalis (Hunter and Husband), Pneumolaelaps longipilus (Hunter), Tyrophagus putrescentiae (Schrank), and Parasitellus fucorum (De Geer). Numbers of mites varied enormously and ranged from 1 individual to over 200 per bumblebee. Kuzinia mites were represented by the phoretic forms (hypopi). Only nymphs of P. fucorum were recorded. Only female mites were recorded for the other mite species. T. putrescientiae, P. longipilus, S. acarorum, and P. fucorum were less abundant, while K. laevis, K. americana, and P. longanalis were the most abundant. These records of T. putrescientiae, P. fucorum, K. laevis, K. americana, P. longipilus, and S. acarorum are the first for Argentine bumblebees.
