Nearly one third of the described species of Cypholoba Chaudoir (Coleoptera: Carabidae) are known to inhabit the Republic of South Africa. A key and diagnostic notes are provided for their identification, as well as notes about way of life for some of the species based on observations in the Kruger National Park. Fifteen species and subspecies of the genus are recorded from the Republic of Sout...

Fossil elytra of a small trechine carabid are reported from the Oliver Bluffs on the Beardmore Glacier at lat. 85°S. They were compared with counterparts from the extant genera Trechisibus, Tasmanorites, Oxytrechus and Pseudocnides. The fossils share some characters but are sufficiently different to be described as a new genus and species. We named the new species Antarctotrechus balli in honou...

Phylogenetic relationships of the Antiperyphanes Complex of the genus Bembidion are inferred using DNA sequences from seven genes (two nuclear ribosomal, four nuclear protein coding, and one mitochondrial protein coding). Redefined subgenera within the complex are each well-supported as monophyletic. Most striking was the discovery that a small set of morphologically and ecologically heterogene...

A new tribe, genus, and species are recognized and described for the beetle family Carabidae. Xenaroswellanini new tribe, Xenaroswelliana deltaquadrant new genus, new species is known from a unique specimen found in 1974 at Lagoa des Pedras, west of the Rio Caña Brava, 160 km NE Brasilia, 15.067°S, 47.078°W, 492 m, Estado de Goiás, Brazil. While the species can be categorized within the Psydrif...

A new species of cave-dwelling Anillini (Coleoptera: Carabidae) Microtyphlus charon n. sp. is described from the “Surgencia de l’Orao” Cave (Valencia, East Spain). M. charon n. sp. is close to two troglobiomorphic species, M. infernalis and M. alegrei (new comb.), sharing the same aedeagus morphology. These three species constitute a monophyletic group that is hypothesized as originating in the...

A diagnosis of the South and Central American genus Cratocerus Dejean (Coleoptera: Carabidae) and a key to all species is provided. Eight species are recognized including six species that are newly described: Cratocerus sinesetosus sp. n. from French Guiana and Peru; Cratocerus multisetosus sp. n. from Costa Rica and Panama; Cratocerus tanyae sp. n. from Costa Rica, Guatemala, and Mexico; Crato...

The Migadopini are a small tribe of Carabidae with 47 species that occur in South America, Australia, and New Zealand, in the sub-Antarctic areas. In South America, most of the genera inhabit areas related to sub-Antartic Nothofagus forest except two monogeneric genera, the Ecuadorian genus Aquilex Moret and the Pampean genus Rhytidognathus Chaudoir. These two genera are geographically isolated...
