“…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).…”

“…This is a matter especially important, due to the current global pollinator declines and conservation needs (Potts et al, 2010). For instance, in the case of Chile, a country with a biodiversity hotspot in its central region (Myers et al, 2000), most recent information comes from original species descriptions and has been contributed by a rather scarce number of researchers (e.g., Ferrari, 2017;González-Vaquero & Galvani, 2016;Monckton, 2016;Packer & Dumesh, 2014;Roig-Alsina, 1991;Roig-Alsina, 1999;Rojas, 2001;Rojas & Toro, 2000;Ruz & Toro, 1983;Toro & Moldenke, 1979;Toro & Rodríguez, 1998;Toro & Ruz, 1969;Vivallo, 2009;Vivallo, 2013;Vivallo, 2014;Vivallo, Zanella & Toro, 2003, among others). Also, within Apoidea, some taxonomic groups receive more attention than others.…”

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.

“…Some types of antennal sensilla in females provided better discrimination. We observed nine types of sensilla on the proximal flagellomeres (F1-3) (Wcislo 1995;Galvani et al 2008Galvani et al , 2012González-Vaquero et al 2016). An interesting result, similar to that of González-Vaquero et al (2016) for Corynura Spinola, 1851, is the absence of sensilla basiconica on the antennae of females.…”

Lasioglossum is a large genus of halictid bees with high species diversity in morphologically rather cryptic species groups. With more than 1900 described species, the taxonomy of the genus is complex and largely unresolved in many regions. For practical reasons, systematic reviews are restricted in scope either geographically or to particular species groups. In this study we focus on the subgenus Dialictus of the genus Lasioglossum from the Yucatán Peninsula in Mexico. In previous studies we identified members of the genus as important pollinators of cash crops in the region, and genetic analyses suggested the existence of seven molecular taxonomic units (mOTU). Based on additional morphological differences, we here describe these mOTUs as novel species, Lasioglossum (Dialictus) yucatanense Landaverde-González sp. nov., L. (D.) paxtoni Landaverde-González sp. nov., L. (D.) ameshoferi Landaverde-González sp. nov., L. (D.) aureoviride Landaverde-González & Husemann sp. nov., L. (D.) paralepidii Gardner sp. nov., L. (D.) milpa Landaverde-González sp. nov. and L. (D.) nanotegula Landaverde-González & Husemann sp. nov., and provide keys and images to assist in their identification.

“…Sensilla length was measured using the Image ProPlus 4.5 program (Ravaiano et al , ). We chose to study the dorsal surface of the antennae of T. fiebrigi because, as previously reported for other bees, sensilla are present in higher numbers and are more diverse on the dorsal surface of the appendage (Ravaiano et al , ; González‐Vaquero & Galvani, ; Carvalho et al , ; Galvani et al , ). In our case, there were fewer sensilla (two types of both sensilla trichodea and sensilla placodea) on the ventral surface of the antennae than in the dorsal surface, and only one subtype of sensilla trichodea on the pedicel of all classes of individuals of T. fiebrigi (Fig.…”

The antennae of the insects have cuticular structures called sensilla that play a pivotal role in the perception of stimuli and in communication. The morphology of antennal sensilla has been characterized in eusocial bees; however, there is little information on bees of the genus Tetragonisca. Using scanning electron microscopy, 11 types of antennal sensilla were identified in Tetragonisca fiebrigi: trichodea (ST, subtypes I-VI), placodea, basiconica, coeloconica, ampullacea, and campaniformia. The largest diversity of sensilla was observed in females. The STI was the most abundant, followed by the placodea and the STII. The STI and the sensila placodea were more abundant in males than females, while the STII were more abundant in workers. Significant differences were found in the length of the different types of sensilla among the classes of individuals, with these differences being greater for the STI in males and the STV in queen; for the STII, STIII, and STIV in queen and workers; and for sensila placodea in queens, workers, and soldiers. Multivariate analysis (PCA and UPGMA) showed that the soldier subcaste was separated from the other females. This study advanced our understanding of sensilla morphology, including the number and distribution of sensilla across sexes and castes, and the sensory structures of T. fiebrigi. The results presented provide relevant information for elucidating the communication mechanisms of social insects.
