All scientific names of Trachypachidae, Rhysodidae, and Carabidae (including cicindelines) recorded from America north of Mexico are catalogued. Available species-group names are listed in their original combinations with the author(s), year of publication, page citation, type locality, location of the name-bearing type, and etymology for many patronymic names. In addition, the reference in whi...

A key is presented for the identification of the four species of Anthia Weber (Coleoptera: Carabidae) recorded from the Republic of South Africa: Anthia cinctipennis Lequien, Anthia circumscripta Klug, Anthia maxillosa (Fabricius), and Anthia thoracica (Thunberg). For each of these species, illustrations are provided of adult beetles of both sexes as well as illustrations of male reproductive s...

While food abundance is known to limit bird populations, few studies have simultaneously examined both temporal and habitat-related variation in food abundance for ground-foraging birds. We surveyed ground-dwelling arthropods throughout the breeding season and in three forest harvest types (clearcut, selection, and shelterwood stands managed for spruce, fir and hemlock) at the Penobscot Experim...

Five new species of the genus Chydaeus Chaudoir, 1854 are described from China: Chydaeus fugongensissp. n. (Shibali, Fugong County, Yunnan Province), Chydaeus gutangensissp. n. (Gutang, Medog County, Xizang Autonomous Region [Tibet]), Chydaeus hanmiensissp. n. (Hanmi, Medog County, Xizang Autonomous Region [Tibet]), Chydaeus asetosussp. n. (NE of Fugong, Yunnan Province), and Chydaeus baoshanen...

The lancanjiang species group of the termitophilous ground beetle genus Orthogonius Macleay, 1825, is defined and reviewed. This group is characterized by the black and rather elongate body, dense punctation on head and elytra, long and slender appendages, thin fore tibiae, and elytral interval 3 without a subapical setiferous pore. To date, the lancanjiang species group is composed of four spe...

The genera Clivinopsis Bedel 1895 and Torretassoa Schatzmayr & Koch 1933 have been recorded in Iraq for the first time. New records of several species of Dyschirius Bonelli 1810 Dyschiriodes Jeannel 1941 (Dyschiriini W. Kolbe 1880) and Clivina Latreille 1802 (Clivinini Rafinesque 1815) are given. The identification key to the species of Dyschiriini from Iraq is provided.

The phylogeny of ground beetles of supertribe Trechitae is inferred using DNA sequences of genes that code for 28S ribosomal RNA, 18S ribosomal RNA, and wingless. Within the outgroups, austral psydrines are inferred to be monophyletic, and separate from the three genera of true Psydrina (Psydrus, Nomius, Laccocenus); the austral psydrines are formally removed from Psydrini and are treated herei...

Growing concerns about the environmental consequences of chemically based pest control strategies have precipitated a call for the development of integrated, ecologically based pest management programs. Carabid or ground beetles (Coleoptera:Carabidae) are an important group of natural enemies of common agricultural pests such as aphids, slugs, and other beetles. Alfalfa (Medicago sativa L.) is ...

Species richness and diversity of Carabidae (Coleoptera), as well as rates of endemicity, are studied along altitudinal transects in the páramo of Ecuadorian Andes, from 3500 to 5000 m. Whereas a global tendency to reduction of species richness is evident from 4200 m upwards, two zones of high diversity and high proportion of endemic species occur at 3800–4000 m and at 4200–4400 m. Species turn...
