Wolbachia bacteria infect approximately 20% of all insect species, and cause a range of alterations to host reproduction, including imposition of thelytoky. The incidence and phenotypic impact of Wolbachia remains to be established in many insect taxa, and considerable research effort is currently focused on its association with particular reproductive modes and the relative importance of the v...

Considering the turmoil and vast changes in the classification of the superfamily Scarabaeoidea during the last 20 years, particularly in North America, we were asked to provide an update for the readers of Scarabs wherein we offer our perspectives. Much of what follows is extracted from our scarabaeoid introduction in American Beetles (Jameson and Ratcliffe 2002). By the time this overview is ...

Restoration of ecological function to abandoned agricultural fields managed for forested ecosystems through afforestation can be measured in various ways. One underutilized method is to chart the progress of known predator-prey-parasitoid systems, and assess the development toward equilibrium of these systems across the forest restoration site. We study the development of the balancing selectio...

ThegenusBancousPic,originallydescribedintheHeteromera(Rhysopaussidae)andlatertransferred to Cucujiformia (incertae sedis), was found to be congeneric withRhamphideraSkelley (Erotylidae).Bancous is here placed in the family Erotylidae (Erotylinae, Tritomini) and Rhamphidera is moved into synonymy. This synonymycreates twonewcombinations:Bancousperplexus (Skelley) andBancous eureka (Skelley).Banc...

-Calaxius galapagensis, a new species, is described on the basis of two ovigerous females from coral rubble in shallow water at North Plaza off Isla Santa Cruz, Galapagos Islands. The species is compared with the eight previously described species of Calaxius Sakai & de Saint Laurent, 1989, and characterized by a strongly tridentate rostral apex, and by rows of corneous spine-like setae on pere...
