Six new species of the genus Taridius Chaudoir, 1875 (Coleoptera, Carabidae) are described from Vietnam: Taridius ornatussp. n., Taridius piceussp. n., Taridius fasciatussp. n., Taridius abdominalissp. n., Taridius coriaceussp. n., and Taridius disjunctussp. n.. The generic characters are redescribed, based on fresh material, with a key provided to all congeners.

Functional diversity is crucial to ecosystem functioning in agricultural landscapes. Intensive agriculture has led habitat homogeneity and thus a decrease biodiversity the disappearance of useful epigeic fauna. This study investigated how local types an landscape affect assemblage parameters (abundance, species richness Shannon–Wiener index) life history traits ground beetles (Coleoptera: Carab...

In this paper a new species of fossil ground-beetle, Calathus elpis n. sp. (Coleoptera, Carabidae) preserved in a piece of Baltic amber (Eocene) is described. A comparison with extant fauna is made, and paleobiology of the species is studied.

Two new species of Pterostichus Bonelli subgenus Pseudoferonina Ball, are described from the mountains of central Idaho: Pterostichus bousqueti Bergdahl [type locality = small tributaries of South Fork of Payette River watershed, ca. 1170 m (3840 ft), 44.0675°; -115.6822°, near Lowman, Salmon River Mountains, Boise County, Idaho, U.S.A.] and Pterostichus lolo Bergdahl [type locality = Cottonwoo...

We report on the species richness patterns of epigaeic beetles (Coleoptera: Carabidae and Staphylinidae) along a subtropical elevational gradient of Balang Mountain, southwestern China. We tested the roles of environmental factors (e.g. temperature, area and litter cover) and direct biotic interactions (e.g. foods and antagonists) that shape elevational diversity gradients. Beetles were sampled...

All genus-group names first proposed or made available for the first time in the third edition of Dejean's catalogue of his beetle collection are recorded. The following 18 names are made available for the first time in Dejean's third catalogue: Batoscelis Dejean [Carabidae], Laphyra Dejean [Carabidae], Sauriodes Dejean [Staphylinidae], Abrobapta Dejean [Buprestidae], Selagis Dejean [Buprestida...

The emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), a phloem-feeding insect from Asia, was identified in 2002 as the cause of widespread ash (Fraxinus sp.) mortality in southeastern Michigan and Essex County, Ontario. Most larvae overwinter as nonfeeding prepupae in the outer sapwood or thick bark of large trees. In a series of studies, we evaluated effects of grindi...
