A systematic revision of Operclipygus Marseul (Coleoptera, Histeridae, Exosternini)
This monograph presents a comprehensive taxonomic revision of the hyperdiverse Neotropical beetle genus Operclipygus Marseul. Operclipygus occurs almost throughout the Americas, but there are few species that extend beyond the diverse tropical regions.ÿ The genus was originally defined very narrowly, for just a single unusual species (the type species O. sulcistrius). However, evolutionary considerations have led to a much broader conception of the genus, and it is now one of the largest in the entire family Histeridae, containing 177 species. In this paper 138 species are described as new. Identification keys are presented to allow identification of all the species, and most species are il...
A systematic revision of Baconia Lewis (Coleoptera, Histeridae, Exosternini)
This monograph presents a comprehensive taxonomic revision of the genus Baconia Lewis (Histeridae: Histerinae: Exosternini). Previously, Baconia contained 27 species. We move four species into Baconia from other genera, and describe 85 species as new, bringing the total to 116 species. Identification keys are presented to allow identification of all the species, and most species are illustrated by color photographs and drawings of diagnostic characteristics. The species mainly occur in the Neotropical region. But several species are known from the U.S., and there are even species occurring in eastern and southeastern Asia. Many of the species of Baconia exhibit brilliant metallic coloration, a feature of as yet unknown significance. Many are also strongly flat-tened, an adaptation for a life under the bark of dead trees, where they are believed mainly to prey on bark beetles and their larvae.
Contributions to Systematics and Biology of Beetles
This volume is dedicated to Professor Igor Konstantinovich Lopatin in celebration of his 80th birthday. Igor Konstantinovich is a renown taxonomist, prolific author, innovative biological explorer, and respected teacher who trained hundreds of students and during his professional life was (and still is) an inspiration and a mentor for scores of taxonomists. His tireless enthusiastic work shaped generations of Belarusian zoologists, brought a wide and steady respect of systematics into a local scientific community. But most important, he taught us that collecting and studying beetles, small and.
