Bombus pratorum santonae (Tkalců, 1985) It spreads mainly in some mountain ranges of the Iberian Peninsula, between 600 and 2152 m (up to 3300 m outside the Pyrenees), in forest biotopes as well as in areas of scrubland, meadows, pastures, gardens, roadsides and even in steppe zones (Castro & Ornosa 1985; Ornosa & Ortiz-Sanchez 2004; Vargas et al. 2013). In the Pyrenees, it has been collected in forest biotopes and meadows of altitude between 1310 and 2152 m (Fig. 7), on Buglossoides arvensis (L.) I. M. Johns., Centaurea scabiosa L., Epilobium angustifolium L., Lathyrus pratensis L., Lotus corniculatus L., Onobrichis vicifolia Scop., Ranunculus pyrenaeus L., Rhododendron ferrugineus L., Silene acaulis (L.) Jacq., Trifolium pratense L., Trifolium repens L. and Vaccinium myrtillus L. According to current records (Table 2), the Pyrenaean population of B. pratorum seems to suffer decline and exhibits greater elevational tendency (Fig. 7). It was relatively common in the past (Ornosa & Ortiz-S��nchez 2004) and it seems to maintain its Iberian distribution. Furthermore, there are recent records outside the Pyrenees, some of them new for the Iberian Peninsula (Castell��n: Fredes, VII-2011, 1 worker, IML leg., 1090 m, C.

Bombus confusus Schenck, 1859 Bombus confusus has a disjunct distribution in Europa and Central Asia (Ornosa & Ortiz-S��nchez 2004). The western population is spread across Europe, with the exception of Fennoscandia and the British Isles. It has already disappeared from large part of its range, and therefore, it is assessed as Vulnerable in the IUCN Red List of European Bees (Rasmont et al. 2006, Rasmont et al. 2015). In the Iberian fauna, B. confusus is a very rare (Fig. 5) and a threatened species that suffers regression (Table 3): eigth individuals were observed from 1 980 until 1991, at isolated points of the Pyrenees and Navarra (Fig. 5), from 600 to 1500 m, on cleared areas of Coniferae forest and alpine pastures. Rasmont (1988) found it in a higher altitude, 1800 and 2000 m, in some records of a couple of localities in the eastern Pyrenees. Nevertheless, several of the scarce Iberian records were based on individuals from 1900 or from 1980���s (Ornosa 2011), where it has not been collected again due to habitat transformation into cereal crops. In 2012, Castro (pers. comm.) found an individual outside the Pyrenees, further inside the Iberian Peninsula. The Pyrenean B. confusus was assessed as Endangered (EN) in the IUCN Spanish Red List (Ornosa 2011) (Table 3). Regardless, strict measures for the protection to this species are urgently required., Published as part of Ornosa, Concepci��n, Torres, F��lix & R��a, Pilar De La, 2017, Updated list of bumblebees (Hymenoptera: Apidae) from the Spanish Pyrenees with notes on their decline and conservation status, pp. 41-77 in Zootaxa 4237 (1) on page 65, DOI: 10.11646/zootaxa.4237.1.3, http://zenodo.org/record/322688, {"references":["Ornosa, C. & Ortiz-Sanchez, F.

Bombus terrestris terrestris (Linnaeus, 1758) It is considered a native subspecies in the eastern Pyrenees, where it reached an altitude of 2200 m. However, repeated introductions in greenhouses (in Barcelona and Almer��a provinces since the 80s) has led to its dispersion to other Iberian areas, where it is already naturalized and can be found at higher altitudes 2500���3400 m (Sierra Nevada, 27���30- VII-2010, 5 workers, P. Vargas leg., RBGM) (Ortiz-S��nchez 1992; Ornosa 1996, Vargas et al. 2013). It has now been collected in the Pyrenees (Table 2) in alpine grasslands and shrublands with scattered patches of subalpine shrub of Juniperus comunis nana Willd. and Calluna vulgaris (L.)

Bombus mocsaryi Kriechbaumer, 1877 Bombus mocsaryi is a wooded-steppes species that is spread throughout dry grasslands in Europe, on the Iberian Peninsula, the south of France, Hungary, Serbia, Romania, Poland, Belarus, Moldova, Ukraine, central Russia until central Asia to the east, and in the north of Africa. In this area it spreads from 690 to 1800 m (Ornosa & Ortiz- S��nchez 2004). At present, in the Pyrenees, it has been collected between 1138 and 1500 m, on Centaurea scabiosa L., Echium plantagineum (Nox.), Melilotus officinalis L, Reseda lutea L., Rubus ulmifolius Schott, Taraxacum officinale Wigg. and Trifolium pratense L. However, at inner territories of the Iberian Peninsula it was located at lower altitudes (Spain: Cantabria: ��liva, 1050 m, 17-VI-2006, 1 queen, C.

Bombus hypnorum (Linnaeus, 1758) This species has a Palearctic distribution. Certain Nearctic records are errors (Williams et al. 2014). The species is assessed as Least Concern in the IUCN Red List of European Bees (Rasmont et al. 2015). In the Iberian fauna, it spreads from Sierra de los Ancares in Cantabrian Range and the Pyrenees, from 750 and 1600 m of altitude (Ornosa & Ortiz-S��nchez 2004). At present, it has been sampled in the Pyrenees in altitude forest meadows with patches of subalpine scrub, in forests of Pinus uncinata and mountain supraforestal, between 1290 and 2035 m (Fig. 7), on Buglossoides arvensis (L.)

Bombus ruderatus (Fabricius, 1775) It is a long-tongued bumblebee species, western Palearctic, introduced in New Zealand and Chile, from where it has spread to Argentina (Schmid-Hempel et al. 2014). According to Rasmont et al. (2015), the species has disappeared from most of its historic locations in the west- and central European lowlands, but despite this regional regression, is considered as Least Concern in the IUCN Red List of European Bees. It has also been found on Madeira and Azores, northern Africa and in the Iberian Peninsula, where it used to be very abundant, between 350 and 2200 meters of altitude (mostly below 1650 meters, but reaching 2800 meters of altitude in Sierra Nevada, Spain) (Castro 1993, Ornosa & Ortiz-S��nchez 2004, Vargas et al. 2013). It shows a slight preference for open areas in the Iberian Peninsula, but it has also been collected in forests, foraging on species of Apiaceae, Asteraceae, Boraginaceae, Fabaceae, Liliaceae, Oleaceae, Papaveraceae, Rosaceae, Ranunculaceae and Scrophulariaceae (Castro 1993, Ornosa & Ortiz-S��nchez 2004).

Bombus maxillosus Klug, 1817 Western Palearctic species, spread by Europe, Minor Asia and the North of Africa. Lecocq et al. (2011) and Rasmont et al. (2015) considerer it as a B. barbutellus subspecies. It is distributed on the Balearic Islands and all over the Iberian territory, except in lower levels of the southern third due to certain orophilus tendency. Its elevational distribution ranges from 870 to 3000 m, and it presents preference for Asteraceae and Fabaceae plant species (Castro 1988, Ornosa & Ortiz- S��nchez 2004, Vargas et al. 2013). B. maxillosus is social parasite on B. ruderatus. It has not been found in the Pyrenees, where it was locally abundant in the past (Table 3), however, there are two recent records in the southern Iberian Peninsula, in Sierra Nevada, on Cirsium vulgare (Savi) Ten.

Bombus subterraneus (Linnaeus, 1758) This is a large bumblebee species distributed in Europe and Central Asia, introduced in New Zealand (Michener 2007). It is considered as Least Concern in the IUCN European Red List (Rasmont et al. 2015). The Iberian population belongs to the subspecies: Bombus subterraneus tectosagorum Kruseman , 1958 It occured mainly in the Pyrenees, entering into inner areas of the peninsula, in the Cantabrian Range and the provinces of Salamanca and Teruel between 1100 and 1900 m, with preference for habitats with more or less open land, with Asteraceae, Boraginaceae, Fabaceae and Lamiaceae (Ornosa & Ortiz-S��nchez 2004). It is a rare subspecies that in recent samplings has not been located in the Pyrenees (Table 3), pointing to its declining poor state of conservation in this area. Only one recent record has been counted in the Cantabrian Range on Echium plantagineum (Nox.) (Le��n: Mara��a, 1275 m, 20-VI-2008, 1 queen, C.

Bombus sylvarum (Linnaeus, 1758) Palearctic species, distributed throughout Europe and Central Asia. Its status in the IUCN European Red List is of Least Concern (Rasmont et al. 2015). It has been collected in the Pyrenees in forest grasslands of mixed oak and pine wood, with patches of subalpine scrub, at 960, 1155, 1320 and 1882 m (Fig. 7), on Antirrhinum majus L., Centaurea scabiosa L., Eryngium bourgatii Gouan and Medicago sativa L. According to the current data this species is clearly in regression, as it was much more common and frequent in the past (Ornosa 1984, Castro 1994, Ornosa & Ortiz-S��nchez 2004).

Bombus gerstaeckeri Morawitz, 1875 Mountain species distributed by the Carpathians, Balkans, Alps and the Pyrenees. The species is considered threatened and is listed as Vulnerable in the IUCN Red List of European Bees (Rasmont et al. 2015). In the Iberian Peninsula it appeared in the Pyrenees (Fig. 6), Cantabrian Range, Picos de Europa and Sierra de Mampodre, between 1100 and 2200 m (Obeso 1992, Ornosa & Ortiz-S��nchez 2004, Castro 2006). This species has not been recorded in the present samplings (Table 3). The total number of collected Pyrenean individuals, from 1971 to 1991, was 88 (Ornosa 1991, Bosch 1999, Castro 2006), but only two of them were collected between 1991 and 2004 (Bosch 1999, Castro 2006). This fact, together with the latest known information (Castro 2006, Ponchau et al. 2006, Ornosa & Castro 2011), indicates an alarming conservation state.

Bombus pascuorum (Scopoli, 1763) It is a western Palearctic species, very common and polytypic, represented in the Pyrenees by two subspecies (Ornosa & Ortiz-S��nchez 2004). It is ubiquitously present in many types of habitats, even in human altered landscapes. Therefore, its status in the IUCN European Red List is of Least Concern (Rasmont et al. 2015)., Published as part of Ornosa, Concepci��n, Torres, F��lix & R��a, Pilar De La, 2017, Updated list of bumblebees (Hymenoptera: Apidae) from the Spanish Pyrenees with notes on their decline and conservation status, pp. 41-77 in Zootaxa 4237 (1) on page 62, DOI: 10.11646/zootaxa.4237.1.3, http://zenodo.org/record/322688, {"references":["Ornosa, C. & Ortiz-Sanchez, F.

Bombus pascuorum maculatus Vogt, 1909 This is a mountain subspecies, spread from the Pyrenees until the Cantabrian Range, between 600 and 2300 m high. Hybrid forms have been observed in the Iberian System, Sierra de B��jar and Sierra de Guadarrama (Ornosa & Ortiz-S��nchez 2004). Castro (1994) considered it a hybrid form of B. pascuorum freygessneri and B. pascuorum dusmeti. At present it has been collected in temperate oceanic Pyrenean forests and supraforestal pastures between 960 and 1992 m (Fig. 7), on Antirrhinum majus L., Buxus sempervirens L.

Bombus sichelii Radoszkowski, 1859 Disjunct species with borealpine distribution, which spread in the Pyrenees, Alps and Balkan mountains in southern Europe and through northeastern European and Asiatic Russia and northeastern Turkey, Iran and the Caucasus, in Asia. The species is considered Least Concern in the IUCN Red List of European Bees (Rasmont et al. 2015)., Published as part of Ornosa, Concepci��n, Torres, F��lix & R��a, Pilar De La, 2017, Updated list of bumblebees (Hymenoptera: Apidae) from the Spanish Pyrenees with notes on their decline and conservation status, pp. 41-77 in Zootaxa 4237 (1) on page 53, DOI: 10.11646/zootaxa.4237.1.3, http://zenodo.org/record/322688

Bombus mesomelas Gerstaecker, 1869 This mountain species spreads in southern Alps, the Caucasus, Turkey and Elburs. On the Iberian Peninsula it occurs in Cantabrian Range, Sierra Cebollera and Sierra de los Ancares and in the Pyrenees, between 1200 and 2900 m of altitude, in open areas and forest areas cleared of fir, oak and beech (Ornosa & Ortiz-S��nchez 2004). At present it has been collected in the Pyrenees in forest pastures, with patches of subalpine and temperate-oceanic Pyrenean forest, between 1440 and 2800 m (Fig. 7) on Asarina procumbens Mill., Centaurea scabiosa L., Cirsium acaule (L.) Scop., Cirsium monspessulanum (L.) Hill, Eryngium bourgatii Gouan, Lotus corniculatus L., Medicago sativa L., Origanum vulgare L., Rhododendron ferreugineum L., Taraxacum officinale Wigg., Trifolium pratense L., Trifolium repens L. and Vicia cracca L. According to the current data, this species exhibits greater elevational tendency (Fig. 7) and the most of the samples were collected above 1650 m. It seems to be locally abundant and it is not regarded as being scarce or threatened (Table 2). In the IUCN European Red List it is considered as Least Concern despite the regression observed in lower mountain regions of central Europe (Rasmont et al. 2015). New records.
