Parasarus Ruz, 1993 comprises small black bees (3-5 mm long) endemic to xeric regions of South America, mainly along of the Andean Cordillera. Prior to this study, the genus included only the type-species P. atacamensis Ruz, 1993 (from northern Chile) which has mesoscutum strongly reticulated and inner hind tibial spur curved apically. In this paper, a taxonomic revision of Parasarus is presented and two new species are described: P. specularis sp. nov. (from central to northwest Argentina… 
DNA barcoding the bees (Hymenoptera: Apoidea) of Chile: species discovery in a reasonably well known bee fauna with the description of a new species of Lonchopria (Colletidae).
TLDR
The diversity of bees in the Chilean fauna is compared with that currently known from DNA barcodes using the BIN system informed by ongoing morphology-based taxonomic research to conclude that the bee fauna of Chile is substantially greater than the 436 species currently known.
Phylogeny and biogeography of the oil‐collecting bee subgenus Centris (Wagenknechtia) (Hymenoptera, Apidae)
TLDR
One most parsimonious tree is found corroborating the monophyly of this group of oil‐collecting bees, with the relationships among its species as follows.

Works including those by Brothers (1975), Brothers and Carpenter (1993), and Brothers (1999) deal with Aculeata phylogeny. Vespomorpha is considered to be a monophyletic clade, although robust

TLDR
A new subgenus of Protandrena Cockerell from South America, Andinopanurgus Gonzalez & Engel, subgen.
A new species of Protandrena Cockerell from Brazil (Hymenoptera, Apidae, Andreninae)*
TLDR
This species is unique within Protandrena for its well-developed pronotal lamella, similar to what is found in Pseudopanurgus and Parapsaenythia, and by its protuberant interantennal area.

TLDR
A biogeographic regionalisation of the Neotropical region is proposed as a hierarchical classification of sub-regions, dominions, provinces and districts that seeks to provide universality, objectivity and stability, such that it can be applied when describing distributional areas of particular taxa or comparing different biogeographical analyses.
Biogeographical transition zones: a search for conceptual synthesis
TLDR
The most heterogeneous places in terms of distributional patterns can be defined numerically on strictly geographical grounds by plotting the frequency of different distribution patterns on maps, and gradual changes in their relative contribution to a given area can be perceived.
