| ABSTRACT Paroxystoglossa is a solitary, ground-nesting bee genus. It was revised in 1960 and currently includes nine species from Argentina, Brazil and Paraguay. The objectives of this contribution are to provide a morphological phylogeny for the group and to describe two new species: P. levigata n.sp. and P. mourella n.sp. Paroxystoglossa is monophyletic and three species groups are recognized, jocasta species group: (P. mourella n.sp., (P. brachycera, (P. jocasta, P. barbata))), transversa species group: (P. transversa, P. levigata n.sp.), and crossotos species group: (P. mimetica, (P. crossotos, P. seabrai, (P. andromache, P. spiloptera))). The crossotos and transversa species groups were considered as sister groups. Interestingly Paroxystoglossa... |

| ABSTRACT The Augochlora clade includes four genera: Augochlora Smith, Augochlorella Sandhouse, Ceratalictus Moure, and Pereirapis Moure. This is one of the richest and most widespread groups of Augochlorini bees. There are about 150 species, which occur from Argentina to Canada. The species of Augochlora clade are considered solitary to facultatively social, except Ceratalictus for which nothing is known. Wood nesting behavior arose once in the clade, in Augochlora sensu strictu. The objective of this study is to describe four new species and to present a revised phylogenetic analysis of the Augochlora clade for the placement of these species. The morphological matrix comprised 77 characters and 42 terminals, and resulted in two most parsimonious trees.... |

| ABSTRACT We describe a new species of the bee genus Xenochlora Engel, Brooks & Yanega, 1997, X. meridionalis sp. nov., based on a single female collected in the coastal forests of southeastern Brazil, in the state of Espírito Santo. The disjunct distribution exhibited by Xenochlora, with species in northern South America and in the Atlantic Forest of eastern Brazil, is discussed in light of current knowledge about other taxa with similar distribution pattern. |

| Entre los grupos basales de la tribu Augochlorini, se encuentra el género de abejas Halictillus Moure, con sólo dos especies descriptas y ninguna revisión sistemática hasta el momento. En este trabajo, se describen cuatro especies nuevas de Halictillus de la Argentina y Chile. Las especies nuevas son: H. amplilobus sp. nov. (de Buenos Aires, Córdoba y Río Negro), H. peninsularis sp. nov. (de la Península de Valdés, Chubut), H. badiclypeus sp. nov. (de Mendoza, La Rioja y Catamarca) y H. reticulatus sp. nov. (de las zonas occidentales de Chubut, Neuquén y Río Negro en la Argentina, y las regiones de La Araucanía y Los Lagos en Chile). Se presenta una clave para la determinación de las seis especies que componen el género, así como descripciones detalladas,... |
