Synopsis of the Argentinian scarab genus Pseudogeniates Ohaus (Coleoptera, Scarabaeidae, Rutelinae)

A new cryptic species and review of the east-Andean leaf chafer genus Mesomerodon Ohaus, 1905 (Coleoptera, Scarabaeidae, Rutelinae)

The Neotropical scarab beetle genus Mesomerodon Ohaus (Scarabaeidae: Rutelinae: Rutelini) is distributed in the western (lowland) Amazonian region from Colombia to Bolivia. Based on our research, the genus includes three species including a new cryptic species from Ecuador. We use niche modeling to predict potential suitable habitat and identify environmental factors associated with the distrib...

A Synopsis of the Genus Areoda (coleoptera: Scarabaeidae: Rutelinae)

Synopsis of the genus Pharaonus (Coleoptera: Scarabaeidae: Rutelinae), with descriptions of new taxa.

An overview of the genus Pharaonus Blanchard, 1851 is presented. Pharaonus farsensis new species and P. adelphus new species are described from Iran, P. lederi turcmenius Ohaus, 1941 is recognized as new synonym of P. lederi (Reitter, 1888), and the subgenus Tamerlanius new subgenus is proposed for the two central-Asian species. New distribution records and systematic notes are presented: P. ca...

Evolution and phylogeny of the scarab subtribe Anisopliina (Coleoptera: Scarabaeidae: Rutelinae: Anomalini)

The subtribe Anisopliina (Scarabaeidae: Rutelinae: Anomalini) is associated with grasses, and its species are distributed in the Palaearctic, Oriental, Ethiopian, Nearctic and Neotropical biogeographical regions. Phylogenetic analysis of adult morphological characters was conducted to examine the monophyly and classification of the group, as well as to examine characters associated with grass p...

REVISION OF THE SOUTHERN SOUTH AMERICAN ENDEMIC GENUS AULACOPALPUS Guérin-Méneville WITH PHYLOGENETIC AND BIOGEOGRAPHIC ANALYSES OF THE SUBTRIBE BRACHYSTERNINA (COLEOPTERA: SCARABAEIDAE: RUTELINAE: ANOPLOGNATHINI)

Phylogenetic analyses were performed on the 17 taxa in the subtribe Brachysternina (Coleoptera: Scarabaeidae: Rutelinae: Anoplognathini) as a means of resolving classification conflicts and of identifying monophyletic groups. Results demonstrated that the subtribe is monophyletic and is composed of three monophyletic genera: Aulacopalpus Guérin-Méneville (nine species), Brachysternus Guérin-Mén...
