Updated list of bumblebees (Hymenoptera: Apidae) from the Spanish Pyrenees with notes on their decline and conservation status Author Ornosa, Concepción Author Torres, Félix Author Rúa, Pilar De La text Zootaxa 2017 4237 1 41 77 journal article 36439 10.11646/zootaxa.4237.1.3 a084a6c4-252b-4a5d-9dd4-af6c3515d7a7 1175-5326 322688 9F7D6E46-B32D-4790-841F-6B7F83DB8D30 Bombus muscorum (Linnaeus, 1758) This bumblebee species has a Eurosiberian distribution. Due to a significant reduction of its distribution range, it is considered as Vulnerable in the IUCN European Red List (Rasmont et al. 2015). In the Iberian Peninsula it can be found in the northern half and at isolated areas in more southern points. Elevational distribution ranges between 410 and 1800 m ( Castro 1994 , Ornosa & Ortiz-Sánchez 2004 ). At present it has been sampled in the Pyrenees foraging in forest pastures and open areas with scrub between 1280 and 1660 m ( Fig. 7 ), on Centaurea scabiosa L., Digitalis purpurea L., Echium vulgare L. , Eryngium bourgatii Gouan , Lotus corniculatus L., Prunella vulgaris L., Silene acaulis (L.) Jacq. Trifolium pratense L. , and Trifolium repens L. It is clearly a declining species in the Pyrenees ( Table 2 ), as well as the entire Iberian Peninsula, where it needs special attention and assessment and very likely, protection. According to the current data, this species exhibits greater orophilous tendency ( Fig. 7 ). New records. Spain : Huesca : Chía , Mirador , Valle de Benasque , 14-VII-2011 , 7 workers , C.
