Abstract
SchwarziaelizabethaeBossert,sp. n., a previously unknown species of the enigmatic cleptoparasitic genusSchwarziaEardley, 2009 is described. Both sexes are illustrated and compared to the type species of the genus,SchwarziaemmaeEardley, 2009. The male habitus ofS.emmaeis illustrated and potential hosts ofSchwarziaare discussed. Unusual morphological features ofSchwarziaare examined in light of the presumably close phylogenetic relationship to other Biastini. The new species represents the second species of Biastini outside the Holarctic region.
Highlights
Biastini (Apidae, Nomadinae) is a small tribe of cleptoparasitic bees with just 13 described species in four genera (Ascher and Pickering 2019)
Four species were treated by Warncke (1982), and B. popovi Proshchalykin & Lelej, 2004 has been described since
The aim of this study is to describe the new species and provide new insights on the classification and morphology of the genus
Summary
Biastini (Apidae, Nomadinae) is a small tribe of cleptoparasitic bees with just 13 described species in four genera (Ascher and Pickering 2019). Biastes Panzer, 1806 is Palearctic and has five described species. Four species were treated by Warncke (1982), and B. popovi Proshchalykin & Lelej, 2004 has been described since. Neopasites Ashmead, 1898 has five described species restricted to the Nearctic; they are morphologically similar to Biastes and the genera were synonymized by certain authors (e.g., Warncke 1982).
