Full title: Phylogeny of the beetle supertribe Trechitae (Coleoptera: Carabidae): Unexpected clades, isolated lineages, and isolated lineages.
Abstract: Using data from two nuclear ribosomal genes and four nuclear protein-coding genes, we infer a well-resolved phylogeny of major lineages of the carabid beetle supertribe Trechitae, based upon a sampling of 259 species. Patrobini is the sister group of Trechitae, but the genus Lissopogonus appears to be outside of the Patrobini + Trechitae clade. We find that four enigmatic trechite genera from the Southern Hemisphere, Bembidarenas, Argentinatachoides, Andinodontis, and Tasmanitachoides, form a clade that is the sister group of Trechini; we describe this clade as a new tribe, Bembidarenini.

Complete title: An annotated checklist of ground beetles (Insecta: Coleoptera: Carabidae) occurring in the state of Sonora, Mexico with descriptions of new species and notes about some collection localities.
An annotated checklist of ground beetles in the family Carabidae from the state of Sonora in Mexico is presented with notes including number of specimens examined, municipios, habitat, vegetation, elevation, and collection dates. The checklist includes 388 taxa, of which 270 are described taxa (included are 19 subspecies and 1 hybrid) and 118 are unnamed morphospecies, in 92 genera representing 35 tribes. Dot maps display where specimens were collected. Three new species are described, with corrected keys and images: Calathus mcclevei, new species (type locality: Mexico, Sonora, Municipality of Yécora, 10 km south of Yécora, ca. 28.278° N 108.926° W); Calathus tigrinus, new species (type locality: Mexico, Sonora, Municipality of Nacozari de García, Rancho El Tigre, 28.3 km (by air) WNW Bavispe, Sierra El Tigre, 30.58988° N 109.20811° W); and Amblygnathus balli, new species (type locality: Mexico, Sonora, Municipality of Fronteras, Rancho Capulín, 23.5 km (by air) WSW Fronteras, Sierra Buenos Aires, 30.76167° N 109.82361° W).
