Abstract

A new species of Longitarsus Latreille, 1829, Longitarsus cohongorooto Konstantinov, new species, with the type locality of Plummers Island, Montgomery Co., Maryland, USA is described. It is illustrated and compared to dark-colored Longitarsus species known to occur in the eastern United States. A key for species identification is proposed. Mertensia (Boraginaceae) is reported as the host plant for flea beetles (Alticini) for the first time. Variability of female genitalic characters is illustrated. The lectotype of Longitarsus traductus Horn, 1889 is designated.
