The bee genusArhysosageBrèthes (Apidae: Andreninae: Calliopsini): new species, taxonomic notes and new distribution records from Brazil

Abstract

A new species, Arhysosage biguttulata sp. nov., is described and illustrated based on adult specimens collected in the Chaco region of Mato Grosso do Sul State, Brazil. This new species can be distinguished by its coloration pattern, pilosity and integumental sculpture. Field observations have revealed several aspects of its life history, such as mating behaviour (similar to other Arhysosage species) and its association with the host plant Opuntia sp. (Cactaceae). In addition, Arhysosage flava is recorded for the first time in Brazil, and type-specimen photographs of Arhysosage cactorum Moure, 1999 and Arhysosage melanothricha Moure, 1999 are provided, along with taxonomic notes.http://www.zoobank.org/urn:lsid:zoobank.org:pub:4E7C7FF9-44C0-4D77-8C78-B4E0F9C4831F

Phylogenetic Relationships of a New Genus of Calliopsine Bees from Peru, with a Review ofSpinoliellaAshmead (Hymenoptera: Andrenidae)

“…The tribe is monophyletic and consists of about 120 species grouped into six genera and multiple subgenera, particularly in the diverse genus Calliopsis Smith (table 1). Revisionary work on the tribe has been comparatively thorough relative to other New World Panurginae, with modern revisions and treatments for the genera Acamptopoeum Cockerell (Shinn, 1965;Compagnucci, 2004;Gonzalez, 2004), Arhysosage Brèthes (Engel, 2000;Ramos, 2013), and Spinoliella Ashmead Ruz, 1972a, 1972b;Rodríguez et al, 2001;Compagnucci, 2015). In addition, faunal revisions and treatments of individual subgenera for Calliopsis or Callonychium Brèthes are also available (Rozen, 1958;Shinn, 1967;Toro and Herrera, 1980;Danforth, 1994).…”
