The species of Colletinae (Hymenoptera: Colletidae) in the Brazilian state of Minas Gerais

Abstract

The Brazilian state of Minas Gerais is a species-rich territory about as large as France, which houses the headwaters of some of the most important rivers in Brazil, as well as a variety of phytogeographic domains, with a poorly known insect fauna. Here, a synopsis of the bee species included in the genera Colletes Latreille, 1802 and Rhynchocolletes Moure, 1943 (Colletidae: Colletinae) occurring in this state is presented, including synonymies, diagnoses, redescriptions and identification keys to females and males of the eight recognized species, including one described as new. These species are Rhynchocolletes albicinctus Moure, 1943; Colletes altimontanus Ferrari& Silveira sp. nov.; C. argentinus Friese, 1908 stat. rev., C. meridionalis Schrottky, 1902; C. ornatus Schrottky, 1902; C. petropolitanus Dalla Torre, 1896; C. rufipes Smith, 1879; and C. rugicollis Friese, 1900. Colletes extensicornis Vachal, 1909 is here proposed to be a junior synonym of C. meridionalis.

Key environmental determinants of global and regional richness and endemism patterns for a wild bee subfamily

“…The final dataset included the entire distributional range of Colletinae but geographic coverage varied considerably because comprehensive faunistic data were available only for a few regions. For the Neotropical Realm, except for a single regionally restricted review (Ferrari and Silveira 2015) Colletes data were especially patchy due to the lack of taxonomic revisions, particularly for the species rich areas of NW Argentina and Mexico (Michener 1979(Michener , 2007. In order to maximize the number of species recorded from this region without making duplicates, records of described but unrevised Colletes species of uncertain taxonomic status only known from the type material were excluded.…”

A tribute to Fernando A. Silveira and his contributions to bee research

“…Two decades after Abelhas Brasileiras was published, this book has received over 1,000 citations (Google Scholar, accessed 03 November 2023). Fernando's contributions to taxonomy, phylogenetics, and biogeography extended well beyond exomalopsine bees, having encompassed other taxa of Apidae, as well as Colletidae, Halictidae, and Megachilidae (Azevedo & Silveira 2005;Ferrari et al 2016Ferrari et al , 2017Ferrari & Silveira 2015;Freitas et al 2018Freitas et al , 2019Freitas et al , 2023Freitas & Silveira 2017;Moure & Silveira 1992;Santos Júnior et al 2015, 2022Santos & Silveira 2009;Silveira 2009Silveira , 2007bSilveira & Martines 2009;Vélez & Silveira 2006;Zama et al 2019), totaling 22 new species and five new family-group taxa (Appendix). His contributions to bee biology were also important and considerably improved our knowledge of Brazilian bees (e.g., Cardoso & Silveira 2012;Carmo et al 2004;Martins et al 1999;Pompeu & Silveira 2005;Silveira 1991Silveira , 2002Simeão et al 2015), and put their conservation on a solid foundation (Machado et al 2008;Pinheiro-Machado et al 2002b;Pires et al 2008Pires et al , 2014aSilveira 2008;.…”

The effects of landscape structure and crop management on insect community and associated ecosystem services and disservices within coffee plantation

“…We sampled wasps (Hymenoptera: Vespidae: Polistinae and Eumeninae), bees (Hymenoptera: Apoidea: . Captured insects were preserved in 70% ethanol and identified to the lowest taxonomic level possible using available identification keys for each of the three insect groups: Michener (2007) and for the bees (family level classification follows , whereas genus-and species-level taxonomy follows Moure et al (2012), complemented by Almeida (2008); Aguiar and Melo (2011), Moure (1994, 1996), Ferrari and Silveira (2015), Freitas and Silveira (2017), Nemésio and Ferrari (2011); Andena and Carpenter (2012), and Santos Junior et al (2015) for Polistinae; , Giordani Soika (1978), Willink…”
