Full title: Phylogeny of the beetle supertribe Trechitae (Coleoptera: Carabidae): Unexpected clades, isolated lineages, and morphological convergence.
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.

First records fo the Palearctic species Trechus obtusus Erichson from the Appalachian region of the Southeastern United States By Curt W. Harden, Michael S. Caterino, Thomas E. Malabad
The Coleopterists Bulletin 76(1): 61–69, 2022
Abstract:
The Palearctic species Trechus obtusus Erichson is reported for the first time from eastern North America. Recent collections in Virginia and North Carolina (new state records) indicate the establishment of the species in the Appalachian region. DNA was extracted from six individuals, and the COI barcoding region was sequenced. All but one of the COI barcode haplotypes were identical to those of T. obtusus collected in western North America. No matches were found with available Palearctic sequences. Individuals of T. obtusus were collected from caves and forest leaf litter, both habitats used by native trechine species.
