We examined diversity, community composition, and wing-state of Carabidae as a function of forest age in Piedmont North Carolina. Carabidae were collected monthly from 396 pitfall traps (12×33 sites) from March 2009 through February 2010, representing 5 forest age classes approximately 0, 10, 50, 85, and 150 years old. A total of 2,568 individuals, representing 30 genera and 63 species, were co...

A new species of the genus Platynus Bonelli, Platynus daviesi, is described from specimens collected in the Appalachian Mountains. The species is structurally most similar to Platynus parmarginatus Hamilton but differs in having the coloration of the body dorsally darker on average, the elytra proportionally longer and wider, the vertex and disc of pronotum with well impressed microsculpture, t...

Stenolophus thoracicus Casey is revalidated. The species is redescribed based on a study of the syntypes and of several conspecific specimens from eastern North America. The species differs from the other eastern species of the subgenus Agonoleptus in having the metasternum shorter and the wings reduced to tiny stubs. The dorsal habitus and median lobe of the aedeagus, along with the structures...

While pitfall trapping is generally accepted as the standard method for sampling carabid beetles, this method has rarely been used in mountain ecosystems, mainly due to the high labour intensity it involves. As part of a research project in the German Alps, we investigated the phenologic appearance of adult carabid beetles in mountain ecosystems along with the consequences of possible reduction...

Cicindis Bruch is a monospecific genus of carabid beetles endemic to Argentina. In this contribution, Cicindis horni Bruch is re-described, with addition of new morphological features of male internal sac, female genital tract and elytral closure. New information on the species' habitat and distribution is also provided. The phylogenetic placement and relationships of Cicindis within the family...

during a faunistic study of the family carabidae in guilan province in summer 2011, beetle specimens were collected directly or by using pitfall traps and light traps. a species of ground beetles was identified and later confirmed by dr. r. felix (berkel enschot, the netherlands) as parophonus dia (reitter). this species is recorded from iran for the first time.
