Phylogeny of the beetle supertribe Trechitae (Coleoptera: Carabidae): Unexpected clades, isolated lineages, and [...]

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.

By David R. Maddison
Annals of Carnegie Museum, Vol 77 No 1 pp.147-193, 2008
Full title: "Systematics of the north american beetle subgenus Pseudoperyphus (Coleoptera: Carabidae: Bembidion) based upon morphological, chromosomal, and molecular data"

A masterful treatment of this immensely difficult group of Bembidion species, with desciption of four new species, detailed illustrations of external morphological characters as well as characters of the aedeagus, discussion on range and habitat preference, and notes on future problems that remain to be solved.

Species of Anillinus Casey (Coleoptera: Carabidae: Trechinae) described from Brazil and their Relation to North American [...]
By I.M. Sokolov & C.E. Carlton
The Coleopterists Bulletin 66(3):245-249, 2012
Full title: "Species of Anillinus Casey (Coleoptera: Carabdae: Trechinae) described from Brazil and their Relation to North American Representatives of the genus.

The authors conclude that two species of Anillinus described from Brazil by Zaballos and Mateu (1997) - A. minor and A. magnus - were based on mislabeled specimens that were actually collected in the state of Georgia, USA. They place A. minor in synonymy with A. steevesi Barr, and move A. magnus to the genus Serranillus. The aedeagi of three Serranillus species are figured (S. jeanelli, S. septentrionis, and S. magnus).
