Revision of the genus Byrsopolis Burmeister, 1844 (Coleoptera: Melolonthidae: Rutelinae: Rutelini), with the description of six new species endemic to Brazil and Paraguay

ABSTRACT

The genus Byrsopolis Burmeister, 1844 is revised and six Brazilian species are described as new: Byrsopolis angeloottatii sp. nov. (Três Lagoas, Mato Grosso do Sul), B. schmidti sp. nov. (Barreiras, Bahia), B. burmeisteri sp. nov. (Cantareira, São Paulo), B. vazdemelloi sp. nov. (Barra do Bugres, Mato Grosso), B. ohausi sp. nov. (Grão Mogol, Minas Gerais) and B. blanchardi sp. nov. (Encruzilhada, Bahia). Lectotypes are designated for B. castanea Burmeister, 1844, B. laticollis Burmeister, 1855, and B. cribricollis Ohaus, 1912. A new synonym is proposed: Byrsopolis aenescens Ohaus, 1926 = B. chassaini Soula, 2010 (syn. nov.). The genus is diagnosed, and all the species are illustrated and compared. The previously published key to genera of Areodina has been updated with the new diagnosis after the revision of Bysropolis. Additionally, an identification key to species of Byrsopolis is provided, with similar characters we made species groups to better identify them, as well as an up-to-date checklist of South American Areodina. A distribution map is also provided and the genus is reported from Paraguay for the first time.
