New synonymies and notes on North American Loxandrus LeConte (Coleoptera: Carabidae)
By Yves Bousquet
The Coleopterists Bulletin 60(2):145-157, 2006
A very useful publication, establishing several new synonymies and defining several 'species groups' for the North American fauna. These informal groups are characterized, and identifying characters are also given for select species.

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).
