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.

Agricultural intensification and expansion has been suggested to be a major driver of the loss biodiversity associated ecosystem services. Recent studies have shown that landscape-level effects in addition on-site management are significant importance for insect declines. We here compared carabid beetle (Coleoptera, Carabidae) assemblages wet meadows among three pairs highly fragmented ‘modern’...

A new species of flanged bombardier beetles is described from Jiangxi and Sichuan, China, Paussus (Scaphipaussus) zhouchaoi sp. n. (Coleoptera, Carabidae, Paussinae, Paussini). All the type specimens were collected from colonies of the host ant Pheidole sp. (Hymenoptera, Formicidae, Myrmicinae). Important morphological characters of the new species are illustrated by color plates.

Cretorabus rasnitsynisp. n., belonging to the extinct subfamily Protorabinae of Carabidae, was described based on a well-preserved specimen from the Lower Cretaceous Yixian Formation of Yangshuwanzi, Inner Mongolia. The diagnostic characters forCretorabus are revised, and the key to species of the genus was presented. The fossil record of Protorabinae was summarized. Sinocarabus Hong, 1982 and ...

A new species of the genus Laelaspis Berlese, Laelaspis elongatus sp. n. is described based on adult female and male specimens collected in association with Pheidole pallidula (Nylander) (Hym., Formicidae) in Ahwaz, Khuzestan Province, southwestern Iran, and also Acinopus (Acinopus) picipes (Olivier) (Col., Carabidae) in Bam, Kerman Province, southeastern Iran.
