The Dynastine Scarab Beetles (Coleoptera: Scarabaeidae: Dynastinae) of Chile

The scarab beetle tribe Pentodontini (Coleoptera: Scarabaeidae: Dynastinae) of Colombia: taxonomy, natural history, and distribution.

Pentodontini is the most diverse tribe of Dynastinae (Coleoptera: Scarabaeidae), and most of the genera are restricted to a single biogeographic region. In this work, the taxonomic composition of the Pentodontini in Colombia was determined, and genera and species were diagnosed based on external morphology and male genitalia. Records of 1,580 specimens from 31 departments and 398 localities in ...

Associations of scarab beetles (Insecta: Coleoptera: Scarabaeidae) with dung of four species of mammals in Khao Yai National Park, Thailand

To determine if dung from various species of native mammals are attractive to species of Scarabaeidae differentially in a seasonal evergreen forest in Thailand, we used pitfall traps baited with fresh dung of four species (barking deer, sambar deer, Asian elephant, pig-tailed macaque) and an unbaited control. The pitfalls were deployed in Khao Yai National Park for 24 hours in March 2010. All t...

Revision of the genus Chalcasthenes Arrow (Coleoptera: Scarabaeidae: Dynastinae: Oryctoderini) from the Solomon Islands

The genus Chalcasthenes Arrow (Dynastinae: Oryctoderini), a scarab beetle genus endemic to the Solomon Islands, is reviewed. Based on examination of type specimens, the genus Strehlia Frey (Rutelinae: Rutelini: Parastasiina) is a new junior synonym of Chalcasthenes. The historical classification of these genera (either in the subfamily Dynastinae or Rutelinae) and character-based criteria for a...

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...
