“…The carinate pronotum evident in these bees may also serve to protect the sensitive areas between the head and pronotum from biting (Pabalan et al, 2000). Similar modifications of the head and pronotum are evident in many halictid bees (Engel et al, 2012;Gibbs et al, 2012a).…”

Abstract.A new species from Colima, Mexico, Lasioglossum (Eickwortia) hienae Gibbs & Dumesh, new species, is described and illustrated. Lasioglossum hienae is distinguished from related species based on a combination of morphological, geographical, and molecular evidence. A species distribution model is used to predict the potential distribution of the known species of L. (Eickwortia). An identification key is provided.

“…These observations suggest that the types of S. karhadra are nothing more than large specimens of S. rufiventris, principally in terms of head width (head widths of S. karhadra are 2.8 mm in the holotype male and 2.2 mm in the allotype female, while in smaller S. rufiventris these measurements are 2.1 mm and 1.8 mm in the male and female, respectively, but intermediates are known). Intraspecific variations in body size, particularly in the head and often resulting from allometry, are not unusual across bees (e.g., Sakagami and Moure, 1965;Danforth, 1991;Packer et al, 2003;Engel, 2008;Engel et al, 2012). Therefore, it is likely that the ventrally divergent compound eyes as well as the clypeus basally more pronouncedly convex are perhaps modifications related with a large body size.…”

“…Although regional taxonomic revisions and species descriptions have been made in recent years (see Dalmazzo and Roig-Alsina 2011;Engel et al 2012;Genaro 2016;Gonçalves 2020a, 2020b), the subgeneric classifications were not properly evaluated. In the present study we describe a new species bearing a mosaic of morphological characteristics found in both subgenera and explore the morphological variation within Augochlora, in order to propose a phylogenetic hypothesis for its main extant lineages.…”

Augochlora Smith, with 127 valid species, is the most widespread genus of Augochlorini bees, ranging from Argentina to southern Canada, including the Caribbean islands. The genus is divided into three subgenera, Augochlora s. str., Oxystoglossella Eickwort, and the fossil Electraugochlora Engel. The extant subgenera were traditionally diagnosed by their nesting substrate, social behavior and morphology. However, accumulating evidence suggests that these features are not reliable for their separation, especially with the discovery of an enigmatic species sharing characteristics from both subgenera. Our objective is to provide a phylogenetic hypothesis to evaluate the monophyly of the extant subgenera and to place a new species, Augochlora (Augochlora) intermedia sp. nov. For this purpose, we compiled 110 unordered characters for 40 species of Augochlora plus seven outgroup species and analyzed under parsimony and Bayesian inference. Topologies were very similar under both frameworks, allowing us to consistently characterize a few major lineages. Our results demonstrate that the extant subgenera correspond to monophyletic groups and the new species is sister group to remaining Augochlora s. str. species. Both subgenera are widespread in the Western Hemisphere, with species groups differing in range and distributional patterns. Our interpretation is that Augochlora arose in South America, subsequently colonizing Mesoamerica, the Caribbean and North America several times. Facultative social behavior can be found in both subgenera and in most lineages, indicating that the exclusive solitary behavior found in Augochlora pura is an exception. Based on morphological clues we interpret that the habit of nesting out of the soil arose once in Augochlora s. str.
