Two new species of <i>Andinopanurgus</i> (Hymenoptera: Andrenidae: Panurginae), with a description of the female of <i>A. amyae</i>

Abstract

Two new species of Andinopanurgus Gonzalez &amp; Engel are described: Andinopanurgus chirosimpson Packer, new species, from northwest Argentina extends the range of the genus south by more than 2000 km and A. lynnae Packer, new species, from Peru. The new species seem to belong to Gonzalez &amp; Engel’s “guarnensis species group” but differ from it in the highly modified setae on S4, which are divided into two to four branches (in A. chirosimpson, the four-branched ones of which look like a thumbless hand and are the source of the specific epithet) to two to five branches (in A. lynnae). The female of A. amyae (Gonzalez &amp; Engel) is described for the first time.

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).…”
