“…Because Bombus dahlbomii Guérin-Méneville is an endangered and conspicuous species (Morales et al, 2016), they were only collected to take into account the relative abundance and after the one hour sampling period they were all released. All specimens collected were identified using existing keys (Toro & Ruz, 1969;Sielfeld, 1973;Toro & Moldenke, 1979;Ruz & Toro, 1983;Chiappa, Rojas & Toro, 1990;Roig-Alsina, 1991;Roig-Alsina, 1999;Toro & Rodríguez, 1998;Rojas & Toro, 2000;Rojas, 2001;Vivallo, Zanella & Toro, 2003;Durante, Abrahamovich & Lucia, 2006;Vivallo, 2009;Vivallo, 2013;Vivallo, 2014;González-Vaquero & Galvani, 2016;Monckton, 2016;Ferrari, 2017). Later, this list was compared to previously published works done in the same location regarding native bee species between 1979 and 1981 (Arroyo, Primack & Armesto, 1982;Camousseight & Barrera, 1998).…”

High-altitude ecosystems are found in mountain chains and plateaus worldwide. These areas tend to be underrepresented in insect biodiversity assessments because of the challenges related to systematic survey at these elevations, such as extreme climatic and geographic conditions. Nonetheless, high-altitude ecosystems are of paramount importance because they have been seen to be species pumps for other geographic areas, such as adjacent locations, functioning as buffers for population declines. Moreover, these ecosystems and their biodiversity have been proposed to be fast-responding indicators of the impacts caused by global climate change. Bees have been highlighted among the insect groups that have been affected by these problems. This work used bees as a proxy to demonstrate and reinforce the importance of systematic surveys of high-altitude ecosystems. Here, field collections were undertaken and an updated review was conducted for the native bee biodiversity of the high-altitude ecosystem found at the Andes system of central Chile, including the phenological trends of these insects during the flowering season. Of the 58 species that have been described for this location, we were able to confirm the occurrence of 46 of these species as a result of our sampling. In addition, thanks to these recent collections, a new species of Xeromelissa Cockerell is described in the present work. These findings highlight the need for further high-altitude insect surveys of this biome, which include both temporal and spatial complexity in their design, to allow for accurate assessment of bee species diversity and compositional changes in these mountain regions.

Megachile is treated here as a single genus combining Megachile with Chalicodoma. In the Americas the genus occurs from Alaska and Canada to southern Chile and Argentina, and is well represented in the tropics. Despite their economic and ecological importance as pollinators, the biology of few species has been studied in detail largely because they are difficult to identify. The 419 species in the catalogue are allocated to 28 subgenera (including 10 Old World species introduced to the region and one species dubiously recorded from the New World). Summaries of information on each species’ classification, biology and geographical distribution are given.

El presente estudio describe las abejas nativas en la Provincia Puna de la Región Andina, en la Reserva Nacional de Salinas y Aguada Blanca en Arequipa, Perú. Los muestreos se realizaron durante siete meses en tres zonas representativas del bosque de Polylepis y del ecosistema Yaretal entre los 3900-4300 m. s. n. m. utilizando dos métodos de colecta: red entomológica y platos amarillos. En total se colectaron 545 especímenes pertenecientes a 26 morfoespecies, diez géneros y cuatro familias. La familia Halictidae presentó la mayor abundancia de individuos 475 (87,1 %), seguida de Megachilidae con 43 individuos (7,7 %), Colletidae 21 individuos (3,8 %) y Apidae con seis individuos (1 %). El género más abundante y diverso fue Caenohalictus con ocho morfoespecies y 466 individuos. Adicionalmente, se colectaron dos especies cleptoparásitas: Acanthopus y Sphecodes. Las áreas de muestreo por debajo de 4100 m.s.n.m. mostraron una mayor riqueza de especies, mientras que el muestreo por encima de 4100 m. s. n. m. mostró una disminución en la diversidad. El muestreo por red entomológica fue el método más efectivo en riqueza de especies (21; 81 %) y el muestreo de platos amarillos en abundancia de individuos (485; 89 %). Los resultados muestran que existe una considerable riqueza de especies de abejas en las áreas altoandinas y resaltan la necesidad de realizar más estudios de abejas en esta y otras ecorregiones del Perú.
