Three new bee species of Rhophitulus Ducke (Hymenoptera, Apidae, Protandrenini) from Argentina and Brazil

Abstract

This work describes three newly discovered species of Rhophitulus Ducke, 1907: R. labiosus n. sp. from Minas Gerais (Brazil), R. mimus n. sp. from Salta (Argentina), and R. xenopalpus n. sp. from Catamarca and Tucumán (Argentina). Photographs of the holotype of Rhophitulus steinbachi (Friese, 1916) are provided, and modifications in the morphology of a female of R. xenopalpus n. sp. when parasitized by Strepsiptera are recorded for the first time for the genus.

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

“…Malvaceae and Solanaceae are the families with most records and are likely pollen sources for these species. Regardless, the discovery of X. imponticula and those species of Spinoliella described here, along with the numerous other new and fascinating andrenids described in recent years from South America (e.g., Ascher et al, 2006;Gonzalez et al, 2013cGonzalez et al, , 2014Ramos, 2014;Ramos and Rozen, 2014), highlight how the diversity of these groups in the region has been underappreciated and overlooked.…”

Three new genera of Protandrenini bees from South America (Hymenoptera, Apidae, Andreninae)

“…The Protandrenini species diversity in many areas of South America remains largely unexplored and underrepresented in collections. The study of museum specimens from distinct regions has been revealing numerous fascinating new taxa in the tribe in recent years (Gonzalez and Engel, 2011;Gonzalez et al, 2013;Ramos 2014;Ramos and Rozen, 2014;Ramos and Ruz, 2015;Sharifi et al 2019;Aguiar and Ramos, 2020;Packer, 2021).…”
