A new species and new records for two other exotic species of Dirrhagofarsus Fleutiaux, 1935 (Coleoptera: Eucnemidae: Melasinae: Dirhagini) in the United States

摘要

New records for a new species and other exotic Dirrhagofarsus Fleutiaux (Coleoptera: Eucnemidae:Melasinae: Dirhagini) species are reported from throughout much of the northeastern and southern areas of the United States. Dirrhagofarsus brevis, new species, is hereby described in this study. Two other exotic species, Dirrhagofarsus modestus (Fleutiaux) and Dirrhagofarsus unicolor (Hisamatsu), new country records, are redescribed and diagnosed as they were compared with other Dirrhagofarsus species present in the Nearctic region. All Dirrhagofarsus species in this study are imaged, highlighting essential character states to facilitate better diagnosis in conjunction to the new identification key provided in this study.
