University of Nebraska State Museum: Entomology Papers
Abstract 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 assigning the taxa to the Dynastinae are provided. We discuss character states that support the monophyly of members of the genus Chalcasthenes, comment on the distribution and biogeography of species in the genus and provide a key to species. The genus includes four …

Ants of the genus Procryptocerus (Hymenoptera: Formicidae) are characterized by the protrusion of the clypeus forming a broad nasus and antennal scrobes over the eyes. The toruli are located directly posterior to the flanks of the nasus opposite to each other. The vertex is deflexed in most species. I present an in-group comparison of the external morphology focusing on the workers. I also present a general morphology for gynes and males. I analize previously mentioned characters as well as new ones, and clarify their character states in different species. For the metasoma I propose a new system of ant metasomal …
