Carabus United States Gulf States distributions


New collection efforts led to re-discovery of Carabus (Carabus) vinctus (Weber) in Louisiana after the first record in 1874. The presumed range of the species in Louisiana is confined to the bottomland forests of the Lake Pontchartrain hydrological system including the lower flows of incoming streams. New locality extends the range of the species in the Gulf States almost 100 miles to the west and represents the most southwestern point of the whole range. Morphologically specimens from Louisiana are close to the Alabama specimens and belong to the var. georgiae Csiki.
